I used this torque wrench for years as a professional bike mechanic - It just hit its lowest ever price in the Amazon Black Friday sale

The Black Friday sales are in full swing, folks. There are all kinds of cycling deals out there, and you may well be on the lookout for others. I'm personally hoping to spot a genuine deal on a bean-to-cup coffee machine.

The Cyclingnews tech team are on the hunt for deals. Stay on top of things with our Black Friday bike deals live page, and our Black Friday bike deals hub.

I like to scout out potential tool deals during sales; I worked as a mechanic for several years, and take a healthy interest in bike and hand tools in general.

I've spotted an excellent deal on the very popular Park Tool TW-5.2 click-style torque wrench on Amazon. Now, this deal is UK-specific, but I've found the best US deal too.

The TW-5.2 currently has a monster 54% off on Amazon UK, meaning you can bag one for £58.38. This is the cheapest the tool has been in over a decade on Amazon and quite possibly ever. It's also being sold by Park Tool's online Amazon store.

In the US, the deal isn't quite as sweet, but I have found a good deal over at Jenson USA on the same unit. If you sign up for Jenson as a member, which is completely free, you can then use the 'INSIDER' discount code, which is advertised on-site. This will let you bag the wrench for $80.76 with 20% off.

A torque wrench is the difference between hoping something's right and knowing it is. This is a great tool to invest in to ensure you're adhering to all manufacturers' torque specs on your bike.

• USA: 20% off at JENSON USA $100.95 $80.76
• UK: 54% off at Amazon £126.99 £58.38

A little on the wrench itself: The TW-5.2 is a small, compact 3/8" square drive torque wrench that covers a 2-14Nm range. Perfect for things like bolts on your handlebars and seat post clamp, up to a Shimano Hollowtec 2 crankset pinch bolt at 12-14Nm.

The unit is adjustable in 0.2Nm increments for accuracy and registers torque values for left and right-hand threaded bolts. It's backed up by a 1-year Park Tool warranty and comes with a tough plastic case.

This certainly isn't the only torque wrench on the market, but it's a very popular model with shops and mechanics as well as home users and is just a solid all-around torque wrench. I've used one an awful lot, and it's never put a foot wrong. Just be sure to zero it after use and try not to drop it or use it as a general ratchet tool.

I spoke with a range of manufacturers and brands on the importance of using a torque wrench. Click the link if you want some extra reading.

This tool's big brother, the TW-6.2, features in my best bike torque wrenches buyers guide if you have your eye on a different kind of wrench.
