Best bike torque wrench overall

1. Pedros Demi torque wrench II

Best bike torque wrench overall

Specifications

Torque range : 3-15Nm
Drive size : 1/4"
Bits included : 8 bits included
Calibration : +/- 4%

Reasons to buy

+
Useful soft tool roll and selection of bits included
+
Will torque left or right-hand threaded fasteners
+
Included bits will cater for most jobs on the bike 

Reasons to avoid

-
Microscale on adjuster could be more accurate 
Buy it if

You want included bits: The wrench comes with more included bits than others. It comes in a protective tool roll with a range of hex and torx bits, including longer ones and a bit holder.

You are regularly installing brake hoses: The 7/8mm crow's foot adapter is perfect for torquing hydraulic brake hose nuts to spec.

Don't buy it if

You want to torque past 15Nm: A lot of bike components dont need high torque rates, but if you do its worth noting this torque wrench only goes to 15Nm. You will likely need another for things like cassette and disc lockrings.

You regularly torque below 3Nm: some components have a 2Nm torque rating, which this wrench won't cover.

The Pedros Demi Torque wrench is our best overall pick, and it brings a lot to the table if you're shopping for a torque wrench.

The wrench itself is a compact and lightweight unit that covers a torque range of 3-15Nm. This will have you covered for the majority of common maintenance tasks on the bike.

You'll be able to torque all of your handlebar and stem bolts, seatpost clamp, and most component bolts like derailleurs and brakes, not to mention a range of accessories and computer mounts.

The wrench comes with 15 included bits, including 2.5, 3, 4, 5, 6 (25mm) hex bits, 4 & 5mm, longer 50mm hex bits and T10, T15, T20, T25, & T30 (25mm), T25 (50mm) Torx bits.

A standout feature of the Demi Torque wrench for me is the included crow's foot 7/8mm adaptor, essential if you're torquing off hydraulic brake hose nuts on shifters or brake levers, a common job on road bikes due to internal cables, particularly for shop mechanics these days.

This torque wrench will comfortably have you covered for torquing things like handlebar controls and saddle and seatpost bolts, but the included bits mean you can do a lot more with it, too, if you need to.

The tool roll it comes in is handy for storage and protection, and there's even a rubber bit holder on the body of the tool to keep common bits close at hand.

Best budget option

2. M Part torque wrench

Best budget torque wrench

Specifications

Torque range : 3-15Nm
Drive size : 1/4"
Bits included : 7 bits included
Calibration : ISO 6789

Reasons to buy

+
Hard case and seven bits included 
+
Competitive price 
+
Nice, loud click off

Reasons to avoid

-
Not as premium feeling as some other units 
Buy it if

You want a good quality, affordable torque wrench: You don't need to spend a lot of money on a torque wrench to work on your bike, and this is an excellent option that is also calibrated to the ISO 6789 UK standard.

You need some hex and torx bits as well: Included hex and torx bits cater for the majority of bikes, and the hard case is useful.

Don't buy it if

❌ You need to work past the 15Nm rating: If you need to torque beyond 15Nm, you will need to choose a different torque wrench.

The M Part torque wrench is our best budget offering and is a great torque wrench for the money.

The wrench itself comes in a hard plastic case and includes six hex bits. These are 3,4,5,6,8,10mm hex bits, and there's also one T25 torx bit. This is a nice spread of sizes and, like Pedro's unit above, will mean you can do a lot on the bike. There is no 2mm hex bit; however, at times a useful size to have, but you can always pick one of those up if you need it.

The unit comes with a calibration certificate in the box, and it's calibrated to the ISO 6789 UK standard, the same as several other wrenches in the guide. It has a loud and satisfying 'click off' when you reach the desired torque, and the micro-scale on the adjuster dial means you can work accurately.

If you want to invest in a torque wrench to use on your bikes but don't want to spend too much, I recommend going for the M Part. It brings a lot to the table for the price.

Best for heavy use

3. Park Tool TW-6.2

Best for heavy use

Specifications

Torque range : 10-60Nm
Drive size: 3/8"
Bits included : No, case only
Calibration : Yes - +/-4%

Reasons to buy

+
Solid and dependable 
+
Clear 'click off' 
+
Nice foam lined case included 

Reasons to avoid

-
1/2" drive size may mean you need a converter socket for some tools 
Buy it if

You need to work up to 60Nm: The high torque range is perfect for torquing things like cassette lockrings, crankset bolts and disc rotor lockrings.

Don't buy it if

You need to torque bolts below 10Nm: Most handlebar stem bolts and seatpost clamps are only torqued to 4 to 6Nm, meaning you can't use the TW-6.2 for these jobs.

The Park Tool TW-6.2 torque wrench is the best option if you want a larger wrench that gives you the ability to work to higher torque ratings. This will be a great option for tightening things like cassettes, chainset bolts and disc rotor lockrings.

The TW 6.2 features a 3/8" square drive head and covers a torque range of 10-60Nm, it’s heavier weight and 36cm length to make it better suited to working on things like crankset bolts and wheels. There’s also a handy Nm to In lb conversion sticker on the wrench that I haven’t seen on another bike-specific unit.

The wrench comes in a sturdy blue case, which is always nice, and the torque is adjusted at the bottom of the wrench using a dial which you push in and rotate clockwise. The dial itself is marked with 0.5Nm increments for increased accuracy, and there’s a clear plastic window further up the body with a scale that increases in 5Nm increments.

This wrench is a staple in many bike shops, and is a quality larger tool if you want to cover even more jobs on your bikes.

There’s a 1-year warranty, and Park Tool offers a calibration service if and when you want to get your unit calibrated.

4. Topeak D-Torq DX

The best electronic torque wrench

Specifications

Torque range : 4-80Nm
Drive size : 3/8" / 1/2" adaptor included
Bits included : Twenty bits included
Calibration : +/-3% for 5000 cycles

Reasons to buy

+
Included 1/2" drive adapter opens up more tool options
+
Calibrated by the ITRI Centre (same as Unior)
+
Zip-up case includes batteries and a big range of sockets and bits

Reasons to avoid

-
Could be cumbersome when working in tight spots
-
Batteries running out could cause an issue 
Buy it if

You want to save time over manually adjusting a non-electric unit: You can set a torque and change between readings very quickly with this wrench, which is a good time saver if your working on bikes regularly

You want some tools included with your torque wrench: Topeak includes a good range of bits and sockets with the D-Torq DX, there's even a nice soft case.

Don't buy it if

❌ You are on a budget: This is a pricier option compared to manual torque wrenches, and represents a bigger investment.

The Topeak D-Torq DX is a really solid option, but it is a little pricier than some of the other units here, overall it's a very strong package.

Here we have an electronic, 3/8" drive torque wrench that covers a huge torque range of 4-80 Nm, meaning this torque wrench can cover nearly everything on a bike. It also comes with AAA batteries included.

If you like the idea of an electronic torque wrench and also like the idea of using one wrench for everything, the D-Torque DX will allow you to hit the ground running.

The unit has an auto-off function, so you don't have to worry about turning it off. You can also preset desired torque values if you're doing the same job regularly.

It comes in a smart case with one of the largest ranges of included bits and sockets, including a 1/2" inch drive converter socket. I also really like the carbon effect surrounding the case; it just looks techy and cool.

An advantage is the ease with which you can set your desired torque electronically with the soft rubber buttons, compared to manually adjusting a mechanical wrench. It's a real time saver, and if you're working on lots of bikes and regularly manually adjusting a wrench, this could be a real selling point.

Though the wrench covers a huge range of torque, it is a little longer than some of the more compact wrenches in the guide and may make working in tighter spots a little awkward, just something to think about, although you could always invest in a smaller or pre-set unit as well.

5. Effetto Mariposa Giustaforza 1-15 Pro Evo

A premium, high end option

Specifications

Torque range : 1-15Nm
Drive size : 1/4"
Bits included : Available with or without bits
Calibration : Yes - ISO 6789 & ASME B 107.300-2010

Reasons to buy

+
Stylish and premium feeling in hand
+
Long bits are very useful for certain jobs 
+
Improved microscale boosts accuracy

Reasons to avoid

-
Premium pricing
-
Bits and Wrench are a little tough to get out of the tool roll 
-
The finish may get chipped or scratched in a shop environment 
Buy it if

You want to treat yourself: The cool finish, weight and nice feel in hand make it feel special to use.

You would like a case and bits as well: Bits are included and everything is packaged neatly in the included roll.

Don't buy it if

You don't want to spend too much: This is a unit at a more premium price point, and you can do the same for less cash, the nice finish doesn't affect performance.

If you want to treat yourself or are perhaps buying someone a gift, then you might want to look at the Effetto Mariposa Giustaforza 1-15 Pro Evo.

Effetto Mariposa overhauled its torque wrench lineup recently, and the 1-15 Pro Evo supersedes the Giustaforza 2-16 Pro model that was previously featured in our guide.

The 1-15 Pro Evo gets an oil-slick finish, which is rather flashy, though admittedly it doesn't bring any extra functionality to the table. It does make for a more special feeling, though.

The Pro Evo gets a 1-15Nm torque range, which has changed slightly from the old units 2-16 and also features a clockwise and counter-clockwise tightening calibration, useful for suspension hardware and the like.

Also new is the new micro-scale on the torque adjusting dial, which also locks into place. I've found this very useful on parts that have a specific torque reading, like 6.2Nm, for example.

The wrench is available on its own or with a nice tool roll and bits, as pictured, for some extra cash. The unit comes with some really useful longer hex bits, which are my go-to for working on brake lever clamp bolts. I don't know what I did before them.

There is also a standard 'Pro' model available for less cash, which is all red, and just loses out on the dual-direction torque tightening feature the Evo gets. There are less expensive wrenches in this guide which offer similar performance points, but if you're looking for a special feeling tool to use at home or work, the Guistaforza remains a nice, high-end option.

Best for workshops

6. Wera Click Torque A5

A slightly larger, workshop quality wrench

Specifications

Torque range : 2.5-25Nm
Drive size : 1/4"
Bits included : No
Calibration : ISO 6789-1: 2017-07

Reasons to buy

+
Comfortable ergonomic handle and nice weight
+
Calibrated to the newest, most stringent ISO standard

Reasons to avoid

-
At 30cm may be too long for some spaces on the bike  
-
No bits included 
Buy it if

You want a quality, well-constructed torque wrench: Comfortable handle and durable finish make this a great option for working with all day.

You want an accurate torque wrench: The Click Torque A5 is calibrated to the newest, most stringent ISO standard.

Don't buy it if

You need to work past 25Nm: Enough range for all but the highest torque needs.

None of your sockets are for 1/4" drive: The 1/4" drive and the fact it doesn't include bits means you may need to invest in extra bits or adapters.

The Wera Click Torque A5 is a 1/4" drive click-style torque wrench with an operating range of 2.5-25nm. This means it's suitable for everything on the bike, except cassette and disc lockrings and larger crankset bolts. It's 30 cm long, making it mid-sized against the wrenches in this guide. It's definitely a tool for home use rather than travelling or riding with.

It's a larger unit and will be highly accurate and reliable, making it ideal for shop environments. The A5 conforms with the ISO678-1:2017 calibration standard and comes with a certificate of conformance. I learnt during my metrology lab visit that the 2017 standard is very stringent and checks the torque wrench across a great many test points.

It uses a 1/4" square drive fitting and doesn't come with bits. So you may need to invest in some 1/4" drive bits and adaptors as needed.

I liked the ergonomic, comfy handle, and if you were using this wrench several times a day, I think it would start to come into its own. The click when torque is reached is also loud and easily audible. Once the bottom adjuster dial is pulled open, the whole lower body of the torque wrench rotates with a really nice light action, allowing you to set the desired torque spec quickly and easily.

This isn't specifically a shop-level tool, but it would make a great addition to any workshop or garage setup. Wera also offers a calibration service in the UK that you can send the wrench back to if needed.

Small and lightweight

7. Feedback Range Click Torque Wrench

A compact unit that feels great in hand

Specifications

Torque range : 2-14Nm
Drive size : Hex bits
Bits included : Yes - 13
Calibration : +/- 4% for 4,000 cycles

Reasons to buy

+
The compact size feels great in hand
+
Nice case and 13 bits included  

Reasons to avoid

-
Exposed spring could get dirty in shop environments
Buy it if

You want a small, portable torque wrench with a case and bits: The compact size and neat case and bits make this a perfect wrench to use at home or when travelling to events.

Don't buy it if

You need to torque past 14Nm or half increments: The 2-14 Nm range is only adjustable in 1Nm increments.

The Range Click Torque Wrench from Feedback Sports is a neat, compact torque wrench, and it comes in a smart travel case with 13 of the usual hex and torx bits, including some longer ones, which I find handy.

The Range Click has a 2-14 Nm range, which increases in 1Nm increments. Feedback is fairly specific about how you hold the wrench to torque things off, so it's worth reading the brand's guidelines for best practice. When torquing something off, you will need to hold the silver end section of the wrench, so use your other hand to hold the head and stabilise the tool.

The wrench promises + / - 4% accuracy over 4000 cycles, and Feedback offers a calibration service of its own. This is a pleasant torque wrench to use and if you like the size and look of the Effetto Mariposa option above, this will provide a similar experience for a lot less cash.

The case is a little on the large side to carry on rides, and it's probably overkill. But the size of the unit overall makes it ideal for taking to events of all kinds, it's compact and neat and won't take up a lot of space. I like its in-hand feel, and for the price, it's a really attractive option.

Best torque multi tool

8. Topeak Ratchet Rocket Lite NTX +

The best multi tool that can tackle torque too

Specifications

Torque range : 2/3/4/5/6Nm
Drive size : Hex bits
Bits included : Yes - 11 included
Calibration : 2 -6 Nm (Tolerance: +10%)

Reasons to buy

+
You can do an awful lot with the included tools
+
A neat and stylish design

Reasons to avoid

-
No audible 'click' from torque unit
Buy it if

You want a multi-tool that can torque things too: The tool comes with loads of bits, a chain breaker and a ratchet tool making working on the bike much easier. You can do a lot with this tool.

Don't buy it if

You prefer your torque wrench to 'click off' when the desired torque is reached: We prefer having a tactile click when using a torque wrench, and this unit isn't very loud, the pre set torque unit isn't as accurate as others either

The Topeak Ratchet Rocket Lite NTX + (phew!) is made up of a useful and well-thought-out range of tools kept in a neat velcro case. Included is a neat ratchet, chain splitter tool, 11 hardened steel hex and torx bits and a pre-set torque attachment that covers a 2-6Nm range. Ideal for working at home, or for travelling with, the case is also small enough that I can carry it in a cycling jersey pocket if required. It's the sort of tool that would be perfect to take on a trip if you need to work on your bike upon arrival.

You could pretty much build a bike with this kit; the 1/4" ratchet is extendable and has a reversible head and a nifty thumb wheel. I like that you can add a hex bit to the other end of the ratchet too, I recently found this useful when installing disc rotor bolts.

The torque attachment is useful and covers a 2-6Nm range, so this will be ideal for setting seatpost heights or adjusting handlebars. It doesn't click when torque is reached; you need to visually align the dashes on the unit, so this is worth bearing in mind. There is a 2-year warranty and pre-set torque accuracy is + / - 10%. This is an ideal tool to carry or have at home to make roadside adjustments and torque bolts. It won't be quite as accurate as a full-blown torque wrench, but if you need a smaller all-rounder, this is a great option.

Best to carry on rides

9. Topeak Nano TorqBar DX

A compact tool to carry with you on rides

Specifications

Torque range : 4/5/6Nm
Drive size : Hex bits
Bits included : Yes - five included
Calibration : +/-6% tolerance is guaranteed for 5000 cycles

Reasons to buy

+
The Torq bar is lightweight and slim in a jersey pocket
+
Clever hex-bit internal storage

Reasons to avoid

-
The click is a little faint to hear and feel
Buy it if

You want a torque tool to travel with and carry easily on rides: Compact size means it allows it to be easily stashed ina pocket or saddle bag.

Don't buy it if

You can't see yourself needing to torque anything out on the road or at an event: The torque adapter doesn't offer any additional functionality beyond its limited torque abilities.

The Topeak Nano Torqbar DX is another great portable option and my go-to for carrying on the bike, especially for road rides, thanks to its small portable size and clever in-built tool storage.

It comes with three pre-set torque limiters of 4, 5 and 6 Nm and a selection of bits in a neat plastic case. You then add your desired limiter and hex bit to the tool body.

What I like is the fact that you can just carry the most relevant torque limiter for your bike and two hex bits inside the handle, making for a really compact setup for your saddle bag or jersey pocket if you want the ability to torque things like seatposts or bars out on the road. It's also long enough that you can comfortably hold and work with it, unlike some super small options out there.

The torque click is easy to miss, though, so you will need to get a feel for this starting off to ensure you don't miss it.

Best pre set torque key

10. Prestacycle Pro TorqKeys 5Nm T-Handle

A preset torque key to use at home

Specifications

Torque range : 4-12Nm - individual tools
Drive size : 1/4" hex bit
Bits included : No
Calibration: No - see below
Buy it if

You regularly work on several bikes: It's really nice to pick up a pre-set tool and torque stem bolts, etc., specifically, and a tool like this can be a real time saver.

You don't enjoy adjusting torque wrenches: There's no adjusting needed here, just pick the tool up and tighten your bolt to spec

Don't buy it if

You want to buy one torque wrench to cover a range of torque specs: Each preset unit covers a specific torque rating, 5Nm, for instance, for handlebar stem bolts. A full-blown torque wrench will allow you to cover more ground.

Here's a really nice little preset torque key from Prestacycle, a company founded in the US. Though there are other preset torque keys in the guide, they are options designed for being carried on rides.

This kind of T-Handle preset unit is best left at home or in the toolbox for when you need to quickly torque something off. The primary use for me would be handlebar stem bolts and perhaps seatpost clamps. It's very convenient to just pick up a pre-set unit and torque your handlebar stem bolts, and the Prestacycle unit feels great in hand.

Prestacycle offers these units in a range of preset torque ratings in 4,5,6,7,8,10 and 12Nm options, so there is plenty to choose from, but for me, the 4 and 5Nm units are the standouts. I find 6mm Hex bits get stuck in thru axles, etc., when used for that in the 10 and 12Nm option.

The tools accept 1/4" bits, and like a lot of preset torque units, have a lifespan of over 5,000 cycles. After that, it will be time to refresh the tool; the brand also points out that doing this is cheaper than paying to have a tool recalibrated in this case. The brand also says that if the logo on the body is worn, it's time to replace it.

How to choose the best bike torque wrench

It's worth spending as much as you can afford on a quality torque wrench; you should end up with a quality, accurate tool.

Here's a quick list of the things that you should consider when shopping for the best bike torque wrench to work on your bikes with.

  • Consider the torque range you need to cover: Not all torque wrenches will measure the same range. Ensure the torque wrench covers your needs. Realistically, you may well end up two torque wrenches, a smaller one with a smaller torque range and a bigger unit for larger jobs.
  • Decide if you need a wrench to use at home or to take with you on rides: Does it need to be light and packable to take on a ride?
  • Decide if you want to go for an electric or manual wrench: Electronic torque wrenches are generally more accurate, but more expensive and not as robust.
  • Consider driver size: If all your tools and sockets are 3/8" size, factor this in. A wrench with a 1/4" driver may at least require an adaptor socket, which can add bulk when working in tight spots.
  • Some tools come with included bits: Do you need the additional bits, or do you already have tool bits that you can use with the torque wrench?

Everything you need to know about the best bike torque wrenches

What is torque?

Torque is the measurement of rotational force that is applied to an object. In the case of bike torque wrenches, that's the bolts that hold your bike together.

When we tighten down a bolt, we stretch the threads, creating friction, which prevents the bolt from coming undone. Too loose and the bolt or screw may work free, but too tight and we may end up causing damage to the component it's holding.

Nearly every bolt or fastener on a bike will carry a torque rating specified by the manufacturer, and is universally measured in Newton meters, abbreviated Nm.

There are other units like in/lb, ft/lb or kg/cm, so make sure that your torque wrench works in Nm to avoid having to convert values each time you use your tool.

Is one torque wrench enough?

In order to be able to torque every component to spec on your bike, you're probably going to need two torque wrenches. Though this isn't a hard and fast rule.

The torque range of components across a bike normally ranges from around 2-3 Newton metres and tops out at around 40-70nm depending on the component in question. Most wrenches won't cover this entire range, so most people or shops end up with a smaller torque wrench for, you guessed it, the smaller stuff and a larger torque wrench to cater for things like cassette lock rings and crank arm bolts.

A smaller torque wrench can be easier to use and will also allow you to easily access smaller bolts that are potentially hard to reach, such as brake calliper bolts and awkwardly placed seatpost clamp bolts.

Is a preset torque key good enough?

For smaller jobs on your bike, you may be fine with a preset torque key rather than needing an adjustable torque wrench. Many small bike bolts specify a torque spec of around 5Nm, so a torque key preset to this value will really help you out. It's nice to be able to pick one up and instantly use it on something like stem bolts.

A torque key for bikes will usually be designed to be highly portable, too, so it's easy to stash in any of the best bike saddle bags.

It's worth noting that not all pre-set torque wrenches can be recalibrated and do have a shelf or cycle life. So if you have been using the same unit for years, it's probably good practice to replace it with a fresh one. Otherwise, you may be unknowingly over- or under-tightening bolts.

Where's the best place to buy a torque wrench?

Don’t be afraid to look beyond cycling brands. Torque is certainly not specific to the bike industry; there is a whole range of torque wrenches on the market. What you should look for is a quality wrench from a known manufacturer that has been calibrated to a standard, so you know it is accurate.

For bikes, that means torque ranges that make sense for the bolts on a bike, and it means scales rated in Newton metres. Purchasing something designed for another industry might be cheaper, but could require constant conversions. Torque is torque, though; as long as you find something that works, it doesn't matter too much what it's marketed for.

How do you use a torque wrench?

Just because you are tightening a bolt with a torque wrench doesn't automatically mean you are getting the correct torque. One of the biggest mistakes is holding the wrench incorrectly. Each wrench has a design that requires a specific placement of force against it. Park Tool has an excellent video covering the details.

Once you know the torque rating of the bolt you want to tighten, set the torque wrench dial or gauge to the relevant rating and begin tightening the bolt. Ensure the hex bit attachment is sitting straight, fully engaged with the fastener you are tightening. Once your desired torque is reached, the wrench will audibly 'click' - or if electronic, 'beep' - letting you know the desired torque has been reached.

You will also be able to feel a physical click in the wrench itself when the desired torque spec is reached. Resist the urge to redo the bolt; you only need to torque it to spec once.

Don't forget to zero your torque wrench once you are finished using it to maintain accuracy.

What are the most common types of bolts found on bikes?

The bolts or fasteners most commonly found on most modern bikes are Hex and Torx bolts. Hex bolts, also commonly referred to as allen key bolts, have a six-sided head. Torx bolts have a six-sided star-shaped head and are visibly different to Hex bolts. In case you weren't sure, most of the regular bolts on your bike will be Hex bolts.

Bicycles don't require big nuts and bolts. The most common size hex bolts found on bikes are 2mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm. If you're looking for a torque wrench with included bits, check what your bike uses and buy the one with the most relevant bits for you. To be honest, most generic torque bit sets will cover a lot of common jobs on a modern bike.

The Torx bolts most commonly used on bikes are T15, T20, T25 and T30. Common uses for these sixes are disc brake rotor bolts, which are often T25, and Shimano chainring bolts, which are T30. Again, if you are shopping for a torque wrench with bits check what Torx bits come with it.

What type of torque wrench is best?

Some torque wrenches are electronic, and some are mechanical. There's nothing that makes one inherently more accurate than the other, but there are reasons you might choose one or the other. The main argument for mechanical is that they don't need batteries. You never run the risk of reaching for your wrench and finding it dead. Also, torque wrenches can last a very long time, and LCD displays don't have the same staying power as a precision metal tool.

Electronic wrenches offer more flexibility and information. If you have a need to measure different units, an electronic torque wrench lets you easily switch between them.

More useful to most people, though, is seeing the torque as you approach your setting. It can feel comforting to know if you are getting close, and loud alarms with blinking lights make it obvious when you've reached your target. It's also nice to be able to precisely set an exact number and have it easy to read. The downside is that the dead zone and click of an analogue wrench when it reaches the set value is easier to feel, and electronic wrenches don’t have that.

Electronic or analog torque wrench?

The way that analogue wrenches and electronic wrenches work is different. Analogue wrenches use a spring and when you get to the correct torque, there's a release of pressure along with a click and some amount of dead zone. Digital torque gauges work the way that a power meter does, with strain gauges. What that means in practical use is that there's no release of pressure and a dead zone in electronic wrenches. But their batteries can run flat, which may catch you out from time to time.

Electronic torque wrenches also have a slightly different feel to mechanical units that can take some getting used to and it can be slightly harder to feel the torque or 'tightness' of a fastener as you tighten it with an electronic wrench. In our experience, this can make you doubt yourself sometimes, and I personally prefer the feel of an analogue torque wrench. If something feels off, don't just blindly proceed; stop and check your work.

Do the best bike torque wrenches need maintenance?

Torque wrenches are precision tools for measuring torque, not general-purpose wrenches or ratchets. If you use your torque wrench to undo bolts, you risk pushing it out of calibration and or damaging it. Always use another allen key or regular wrench for loosening bolts, and only use your torque wrench for tightening to spec.

For the same reason, you also want to be sure to zero the wrench when you finish using it. Leaving the wrench spring in tension during storage will affect calibration over time. It only takes a moment to set the wrench to the lowest setting before storing it, and it will make sure you get the most precision out of an expensive tool.

Most manufacturers recommend a calibration check yearly. This is not particularly expensive to get done and will ensure your wench is still operating in the correct range of torque. However, I used my own torque wrench day in and day out for a few years, dropped it and left it wound on more than once, and it passed a metrology lab calibration check and was still in spec, so don't fret if you don't calibrate your wrenches for years. It's best practice, not the law.

Try to avoid dropping your torque wrench and always store it in its case or bag. Temperature extremes can also affect the accuracy, and a few practice 'clicks' before you begin working will provide more accurate results as the spring in your click-style torque wrench warms up.

Do I have to use a torque wrench?

You don't have to use a torque wrench on your bike, but it is advisable and best practice to do so.

Using a torque wrench is the difference between hoping something is right and knowing it is. This is especially important if you are working on bikes for other riders or customers.

Using your own feel when tightening bolts will get you pretty close (if said feel is decent), but ultimately it's just a guess.

A torque wrench eliminates any doubt and confirms your components won't be damaged or vibrate loose on your bike. In the event of a warranty issue, you'll be in a better position.

How do I find the torque rating of a part?

Components like handlebar stems, seat post clamps and crank bolts often will have torque ratings listed on them somewhere by the manufacturer. But often things like derailleur bolts and brake pinch bolts will all have torque ratings, but you may have to look them up.

Manufacturers' websites will have torque specs listed, but Park Tool also has a very useful table of torque specs here for you to reference.

Should I grease the threads of bolts before I torque them?

An assembly compound, such as grease or anti-seize etc is often recommended by manufacturers when assembling components and tightening bolts.

Friction between dry threads can lead to inaccurate torque readings. It's best to adhere to the manufacturer's specs if you are unsure, but grease and/or anti-seize is a good idea on nearly every threaded fastener. If you aren't sure, pick up the phone and ask the manufacturer or retailer for best practices.

Torque terms glossary

Torque Terminology Glossary

Some specific terminology comes with torque wrenches. We are going to outline some of the common terms in this guide before we begin, so you can follow the buying advice easily and understand everything. We know it can be confusing sometimes when you keep reading a term, but don't completely understand what it means or refers to.

  • Torque: A way of measuring the force applied to an object that moves.
  • Newton metre (Nm): A measurement of torque
  • Square drive: The square connection on the torque wrench that can connect with a range of sockets or tools
  • Bits: The small Hex or Torx tool bits are used to work on the bolts on your bike.
  • Convertor Socket: A socket that for example allows you to fit 1/2" sized sockets to a 1/4" drive tool, allowing the use of a wider range of tools

How we test the best bike torque wrenches

Research:

How we test for this guide begins with researching and reading about as many of the relevant torque wrenches on the market as I can find. After receiving a test unit, I then went back to the manufacturers or distributors with any additional questions I had.

Initial inspection: I inspected all of the torque wrenches on arrival for any defects or quality issues and photographed them. I also take into account packaging, for example, if there is a lot of non-recyclable plastic or unnecessary packaging.

Workshop testing:

I then use and test all of the torque wrenches we review on a range of different bikes, components, and service jobs to see how they operate. The larger wrenches were used in my home workshop, and the smaller compact ones I travelled with or carried with me on rides.

Repeatability and consistency:

I repeatedly performed lots of jobs that you would expect a torque wrench to be used for by a bike mechanic or home user. From torquing stem and seat clamp bolts to spec to torquing chainset spider lockrings and larger crank bolts. It's important to repeatedly work with and use the tools; a single test may not be a true indicator of performance.

I've been into working on my own bikes most of my life. I'm a qualified bike mechanic and before I joined Cyclingnews I ran a servicing and repair workshop for five years. As a tool nerd, I enjoy researching, testing and writing about tools for bikes generally. I've tested every tool here on dozens of bikes and carried out all of the major servicing jobs requiring a torque wrench on each one. I am confident that any one of these options will help improve your maintenance work, look after your bikes and keep you safe.

Tom joined the Cyclingnews team in late 2022 as a tech writer. Despite having a degree in English Literature he has spent his entire working life in the cycling industry in one form or another. He has over 10 years of experience as a qualified mechanic, with the last five years before joining Cyclingnews being spent running an independent workshop. This means he is just as happy tinkering away in the garage as he is out on the road bike, and he isn’t afraid to pull a bike apart or get hands-on with it when testing to really see what it’s made of. 


He has ridden and raced bikes from an early age up to a national level on the road and track, and has ridden and competed in most disciplines. He has a keen eye for pro-team tech and enjoys spotting new or interesting components in the wild. During his time at Cyclingnews, Tom has already interviewed some of the sport's biggest names including Mathieu van der Poel, Tadej Pogačar and Alberto Contador. He's also covered various launches from brands such as Pinarello, Ridley, Specialized and more, tackled the Roubaix Challenge sportive aboard his own rim-brake Cannondale SuperSix Evo, tested over 20 aero helmets in the wind tunnel, and has created helpful in-depth buying advice relating to countless categories from torque wrenches to winter clothing.
