Choosing the best road bike for your requirements is not as straight forward as it once was. With huge advancements in material, design and manufacturing processes road bikes have branched out into many different categories and specialities. Making an informed decision then, all comes down to the type of riding you enjoy and the topography involved.
A lightweight climbing bike will dance up the steepest of climbs but on fast flat or rolling terrain, noticeably more effort is required to keep up with an aero road bike. If riding long distances is your thing then the energy savings of an aero road bike might be tempting but a stiffer ride and optimisation for efficiency at higher speeds don't necessarily translate well when you plan on pushing the pedals from sunrise to sunset.
As each manufacturer innovates to better the competition, they are producing bikes that go beyond what was ever thought possible. From adjustable compliance on aero road bikes, integration and built-in storage solutions to road bikes that go beyond the limits of tarmac to open up even more riding possibilities - we've got you covered. Componentry such as electronic shifting, power meters and disc brakes have become common on many more bikes as well, giving an even wider set of criteria to consider.
To help you choose your next bike we have a number of guides filled with information to help you choose the best possible option in each category. However, some bikes are just that little bit more exceptional than others so here, we have chosen the bikes we think stand out in each category.
Scroll down for a pick of the road bikes that we have selected as the very best of their categories.
Best race bikes
Lightweight, efficient and aggressive, these rulers of the road are the top of the food chain when it comes to one bike that will perform no matter the course. Whether tackling long climbs, battling windy flats or carrying as much speed as possible through corners, these race bikes are designed to be as fast as possible.
Aggressive positioning and geometry meet a carefully considered blend of aerodynamic performance, low weight and stiffness to produce the most uncompromised road riding experience possible.
The SuperSix Evo has long been the gold standard in race geometry and handling, and now it’s more compliant and aero
Frame: Hi-Mod Carbon | Brakes: Disc | Weight: 7.3kg | Sizes: 48cm-62cm
Launched just ahead of the 2019 Tour de France, Cannondale's latest SuperSix Evo comes complete with a first for the frame – a sloping top tube. But it's not just the death of the flat top tube, Cannondale has swapped to Kammtail tube shapes for a claimed 30 watt saving (at 48kph) over its predecessor and the brand says the new SuperSix is between nine and 40 watts faster than a range of its competitors. The frame also gets a flat-backed seat post and seat tube, and the dropped chainstays which are becoming increasingly common among carbon race bikes. Capable of taking 30mm tyres (28mm rim brake), the new frame is claimed to weigh 886g in a size 56, painted.
Cannondale has also opted for an integrated bar and stem and sees the brands in-house KNOT components providing the seat post and wheelset. As you'd expect for a bike in this price bracket, the 45mm deep road wheels are carbon fibre and tubeless-ready, and a Shimano Dura-Ace Di2 groupset provides the gearing. The new SuperSix EVO also comes with a Power2Max NG Eco power meter installed in the HologramSiSL2 cranks, though you'll have to pay a fee on top of the retail price to activate it.

Giant TCR Advanced Pro 0 Disc
The TCR begs to be ridden like you stole it, and comes with a price tag that makes you feel like you might have
Frame: Advanced-Grade Composite carbon | Brakes: Disc | Weight: 7.64kg | Sizes: S-XL
Giant's TCR has long been a no-nonsense performer, and the brand as a whole demonstrates top value for money. Designed around the brand's compact road geometry, the frame is built using Giant's Advanced Composite Technology, and moulded in a modified monocoque construction — meaning the front and rear triangles are moulded separately and then bonded together.
The TCR has always been known for its snappy ride quality and that's due in large part to its compact rear end. At the front, the TCR gets Giant's chunky Overdrive steerer which combine with the front and rear thru-axles and stiff carbon fork mean no steering input is lost to flex.
- A closer look at the new Giant TCR - Simon Geschke's 6.4kg bike
- Greg Van Avermaet's golden Giant TCR Disc - Gallery
Depending on where you live, the Advanced Pro Disc comes with either a Shimano Ultegra or SRAM Force eTap AXS drivetrain, but, regardless of your region, the wheels and tyres are tubeless-ready out of the box, meaning they come with valves and rim strips installed and Giant even gives you enough sealant to get rolling.
The Giant TCR has recently been updated and promises improvements all-round. Initial impressions are positive, but a full review is in the works. This does mean the current model TCR is soon to be deemed 'old-hat', but that should mean discounts are readily available on what is still an excellent bike.
Specialized S-Works Tarmac Disc Dura-Ace Di2
The Tarmac has been one of the most successful racing platforms to date, and the SL6 frame makes it faster in the wind tunnel, adds vertical compliance and tyre clearance while shedding weight
Frame: FACT 12r carbon | Brakes: Disc | Weight: 6.58kg | Sizes: 44cm-61cm
We're up to the SL6 version of the Specialized Tarmac, and the current frameset has lost a bit of weight and the tubing profiles are a bit boxier. The chainstays have been dropped drastically, and the back of the seat tube and seat post are now flat, a well-tested way to introduce compliance to the rear end.
Introduced a few iterations ago, the new Tarmac is based around what Specialized calls Rider-First Engineering, each frame size is built with a specific geometry, layup and tube shapes, meaning gone are the days of the ultra-stiff XS and noodly XL frames. Also gone are the gender-specific geometries, the only difference between the men's and women's versions are the touchpoints and cranks.
Specialized tell us the frame is more aero too, claiming the new Tarmac is 45-seconds faster over 45km compared to 'other lightweight bikes in the same category'. Only available with disc brakes for 2020, this has allowed the brand to balloon the max tire clearance to 30mm. The Expert spec comes with a Shimano Dura-Ace DI2 groupset, Roval CLX 50 Disc carbon wheels finished in with S-Works Turbo 320TPI rubber in pleasing tan wall.
Pinarello Dogma F12
Top-end racer with the price tag to match
Frame: Carbon Torayca T1100 1K Dream Carbon | Brakes: Disc or rim | Weight: 840g (frameset, unpainted) | Sizes: 42cm-62cm
Say what you will about Pinarello's Dogma but it has won seven of the last 10 Tour de France's. The latest iteration of the Italian brand's aero racer is the Dogma F12, and it's the first race bike from Pinarello to come with discs from the outset. It's quite a big deal given in 2017 Fausto Pinarello famously declared he wasn't convinced high-performance bikes needed disc brakes. The rim brake version also swaps from a single bolt to direct mount brakes.
At first glance, the F12 doesn't look all that different from the F10; there are quite a few claimed improvements to aerodynamics and stiffness throughout the frame. The fork has been revamped to better combat twisting forces from the disc brake caliper, and the frames themselves are said to be 10 per cent lighter than the F10 (unpainted). Pinarello has also made refinements to its asymmetric frame design and changed to a higher grade carbon, said to amount to a 10 per cent increase in stiffness.
Now with the ability to take 30mm tyres (28mm for rim brake version), the F12 is designed around the Most (Pinarello's component brand) Talon bar and stem combo, which is available in 16-stem length and bar width combinations. Pinarello is making the Dogma F12 in 13 frame sizes, however, they are so expensive, most retailers seem to only be offering framesets at the time of writing.

Best aero bikes
The introduction of aerodynamics into road bikes has been one of the most defining advancements in cycling history. Gone are the svelte tubes of artisan frames, instead frames are now designed by computers using computational fluid dynamics to sculpt wind-cheating shapes.
The result is lightning-quick bikes that destroy high speed flat and rolling roads. The advantages of aerodynamics are so great that elements have spilt over to all high-end bikes, however, nothing will match an all-out aero road bike in terms of raw speed.

Cannondale SystemSix Hi-Mod
The fastest bike Cannondale have ever made
Frame: Hi-Mod Carbon | Brake: Disc | Weight: 7.6kg | Sizes: 47cm-62cm
The SystemSix moniker is nothing new to Cannondale, having first appeared 12 years ago in the form of a hybrid carbon fibre/aluminium composite frame. Ahead of its time in many ways, it paved the way for future models such as the lightweight and dynamic SuperSix Evo, which has also been given the aero treatment.
The blueprint of the all-new SystemSix - Cannondale's first dedicated aero road bike - has been touted by the American company to be the 'fastest on the planet'. At 7.8kg it may seem a little on the portly side but Cannondale says the added grams will do little to thwart progress, even on the hills.
The SystemSix makes an endearing case for itself as far as free speed is concerned. It's seriously fast - be it on a descent, flat or climb, and the powerful disc brakes make for controlled modulation mid-corner.

Trek Madone SLR 9 Disc eTap
Trek's flagship road bike is faster and more comfortable than ever before
Frame: 700 Series OCLV Carbon | Brake: Disc | Weight: 7.98kg | Sizes: 50cm-62cm
You'd expect something as aero-looking and performance-orientated as the Trek Madone to possess a harsh and unforgiving ride quality but it doesn't. Like the Domane, the Madone also utilises an IsoSpeed decoupler, but in this application, it's located in the top tube and offers a certain degree of adjustability – something Trek claims has boosted comfort and stiffness by 17 and 21 per cent respectively.
The Madone however, has always been a proponent of aerodynamic trickery and, as such, employs a compendium of clever go-faster techniques such as an integrated two-piece carbon bar and stem (SLR models), Kammtail Virtual Foil tubing and disc-equipped aero wheels that will accommodate tyres of up to 28mm.
A lighter rim brake version is also available with repositioned front brakes behind the fork for improved aero proficiency. As the range-topper in the Trek road bike range, all Madones feature carbon frames and high-end SRAM or Shimano groupsets.

Specialized S-Works Venge Disc
Specialized has managed to make its aero road bike lighter and more user-friendly without jeopardising its straight-line speed
Frame: S-Works FACT 11r carbon | Brake: Disc | Weight: Unpublished | Sizes: 49cm-61cm
The third-generation Specialized Venge is the lightest version yet with dropped seat stays and shaped tubing that make for an aggressive and purposeful facade.
Honed in the company's 'Win Tunnel' wind tunnel, the Venge favours speed and performance over comfort – Specialized claims the new Venge will save you 8 seconds over 40km compared to its predecessor, the Venge ViAS.
That's not to say it's bereft of any sense of compliance. While it may not boast the fancy suspension trickery of the Roubaix, the Venge gains added levels of comfort by way of bigger tyres and lower pressure, it can handle rubber of up to 32mm.
The new model also benefits from a more user-considered build - for example, split headset spacers enable adjustment without the need to re-cable the entire front end.
For those that really want something special, for an extra £500 Specialized do a limited edition Sagan Collection Venge which comes equipped with Shimano Dura-Ace Di2, S-Works Power Cranks and limited edition paint with holographic details.
Best climbing bikes
While bike design has splintered road bikes into specialist performers by making gains through truncated this and compliance that, when the road starts pointing up and gradients become severe lightweight is still king. It's a simple fact that the less weight needing to be powered up a climb will result in a faster climbing speed.
The UCI limits the bike weight to 6.8kg for racing and while many brands seem to use this as a stopping point, for the everyday road rider, weight weenism can easily take a bike well below the racing limitation for even greater performance.
Wilier Zero SLR Disc Dura-Ace Di2
Thoroughly modern lightweight bike from one of the oldest racing bike manufacturers in the world
Frame: Carbon | Brake: Disc | Weight: 6.8kg | Sizes: XS-XXL
Despite their illustrious histories, Italian manufacturers are generally not renowned for being on the cutting edge of bicycle design. We tend to think of Italian racing bikes as beautiful, classic, perhaps even old fashioned – but the reality is that, with Wilier at least, this couldn't be further from the truth.
The Zero SLR Disc is the latest lightweight bike from Wilier. Borrowing design cues from their Cento10 Pro aero bike, it's a thoroughly modern lightweight bike. It ticks all the boxes; a super lightweight carbon frame with truncated aerofoil tube shapes, integrated handlebars with fully hidden cables, hydraulic disc brakes, carbon wheels and clearance for 28mm tyres.
Its tried and tested geometry, and stiff frame and fork mean handling is great, and its clean lines and complete cable integration make it a real looker. Wilier is kind enough to offer some very nice paint jobs as well – matte black with white detailing, matte velvet red and a glossy admiral blue. The matte black frameset is slightly lighter, but go for the red or blue for that essential touch of Italian flair.
There's no denying that this is a pretty expensive bike – Wilier retains that classic Italian bike characteristic – but you're buying into a European brand with over 100 years of experience in making bikes, and all of the racing heritage that comes with that.
As of yet, there doesn't appear to be any women's specific versions available, but, hopefully, that’s something Wilier will offer in the near future.

Trek Emonda SLR 9 Disc
A superbike designed in conjunction with Alberto Contador, that’s now just as quick going down hills as it is at going up them
Frame: 700 Series OCLV Carbon | Brake: Disc | Weight: 6.42kg | Sizes: 47cm-62cm
Once a pure climbing machine, built to give Alberto Contador an ideal platform on which to unleash his infamous out of the saddle attacks, the addition of hydraulic disc brakes and clearance for up to 30mm tyres widens its potential remit considerably.
With Dura-Ace Di2 and Bontrager Aeolus XXX 2 wheels, the Trek Emonda SLR 9 Disc flaunts the UCI weight limit by an impressive 380g. This is thanks largely to its superlight frame which is, rather incredibly, claimed to weigh just 665g.
Available in a wide range of sizes and finished with impressive components from Bontrager, all of Trek's bikes can be customised through their Project One programme. The options are extensive – from paint jobs through to practically every major component on the bike (though naturally, any upgrades will increase the overall cost) – so if the stock Purple Phaze paint job isn't to your taste, for example, you should still be able to find something to suit.

Canyon Ultimate CF Evo 10.0 SL
Outrageously light, super-efficient bike with top-of-the-line spec
Frame: Carbon | Brake: Disc | Weight: 6kg | Sizes: XXS-XXL
With Canyon's direct-to-consumer approach, it's hard to argue the value for money aspect of the German behemoth's range. While this particular model is still a significant investment, this is competing against superbikes that are breaking the £10K without a sweat.
Canyon claims its Ultimate CF Evo is the lightest carbon disc brake frame on the market which is paired with a feathery 285g fork. Canyon state that this frameset, including handlebar, stem and seatpost, weighs 1.51kg. Not only is the frameset light, but Canyon confidently back up the stiffness of the frame which they say has been achieved using their most advanced carbon layup. The pursuit of weight-saving extends to the finishing touches like a titanium internal seatpost clamp to assure every gram possible has been saved.
Canyon hasn't looked to have scrimped on components either, your £7,449 gets you some serious kit. Canyon provides an impressive selection of SRAM’s RED eTap AXS groupset including a RED D1 power meter, DT Swiss 25th Anniversary disc carbon clinchers, and the CP20 EVO Evocockpit. Finishing touches come from the German lightweight carbon specialists Schmolke's 87g seatpost and a 69g Selle Italia SLR C59 saddle.

Best endurance bikes
For those who seek long days on the road, an endurance road bike with relaxed geometry, larger tyre clearances and built-in comfort features make a huge difference when the miles start racking up. Many of the best endurance road bikes feature compliance zones, optimised tube shapes or suspension systems to isolate the rider from poor road surfaces and fatigue-inducing vibrations. Relaxed geometry, larger tyres and disk brakes make these bikes steady and predictable, ready to tackle any long-distance ride no matter the terrain.
Specialized S-Works Roubaix
With a more adjustable future shock that's less 'springy' Specialized has created a more balanced ride, adding compliance to the rear end
Frame: FACT 11R carbon | Brakes: Disc | Weight: Unpublished | Sizes: 44cm-61cm
The Specialized Roubaix was the first commercially available endurance road bike when it was launched back in 2004. With a slightly more relaxed geometry and taller head tube, early versions of the Roubaix featured Zertz inserts, said to absorb road buzz — their effectiveness is still up for debate.
The Roubaix has come quite a long way since then, now featuring the Future Shock. Designed in collaboration with McLaren, the Future Shock is now in its 2.0 version and features a hydraulic piston inside the head tube which provides 20mm of travel, now with a dial to adjust the compression and rebound damping.

It's not as snappy as the Tarmac when you push on the pedals, but it does an excellent job of smoothing out square edges on the road. Specialized are firm believers that 'Smoother is Faster' but so is aero. The Roubaix has had the 'Win tunnel' treatment and according to Specialized, the new Roubaix is more Aero than the Tarmac SL6 yet lighter than a Venge. Like the Tarmac, it only comes with disc brakes and a unisex geometry, with the only difference between the men's and women's bikes being the touchpoints.
Trek Domane SLR 9 eTap
Keeping with the trend of people taking road bikes past where the road ends, the Domane is comfortable on tarmac and light gravel
Frame: 700 Series OCLV Carbon | Brakes: Disc | Weight: 8.17kg | Sizes: 47cm-62cm
The third generation of the Trek Domane carries the dual front and rear IsoSpeed technology. The rear IsoSpeed uses a top-tube mounted adjustable pivot that with just a couple of tools and 5 minutes will allow the amount of compliance to be adjusted to suit your next ride whether its road, pavé or light gravel.
Trek says the new Domane is more aero than its predecessor, with Trek claiming it's a full minute per hour faster than the previous version - although at what power output, we cannot be sure.
Trek has fully committed the Domane to disc brakes and the result is that it can accept up to 38mm tyres, or 35mm with a fender. At the front, there is a nifty cable guide mounted under the stem; it's not quite as clean as the internally routed options, but not having to run cables and housing through handlebars and stem make maintenance and changes to bike fit considerably easier.
The Domane also features a clever down tube storage box that allows for tools and a spare tube to be stored in the frame inside a plush tool roll. While the standard Domane range is built around Trek's H2 Endurance Fit, if you spring for the Project One SLR, the slightly more aggressive H1.5 'Pro Endurance' geometry is available. Trek has also ditched the gender-specific geometries, with the only difference between the gendered bikes being the touchpoints and paint jobs.
BMC Roadmachine 01 One
The ideal bike for those looking for a race bike dressed like a Gran Fondo rider
Frame: TCC Endurance Premium Carbon | Brakes: Disc | Weight: 7.55kg | Sizes: 47cm-61cm
At first glance, the BMC Roadmachine looks identical to the Teammachine racer, but closer inspection reveals a higher stack, shorter reach, softer ride and room for fat tyres. Even with the more relaxed geometry the Roadmachine still retains much of is racier cousin's efficiency and snap when pressure is applied to the pedals, but with slightly more forgiving steering characteristics.
The frame is made using the TCC (Tuned Compliance Concept) Endurance lay-up, which BMC says is designed to take the edge off rough roads. BMC has also employed what it calls Angle Compliance technology, which is marketing-speak for flex built into the fork, seat stays and seat post. The Roadmachine is where BMC first employed its integrated cockpit design, so it's no surprise to see it here and we love the addition of mounts for a top tube food/storage box so your pre-knock Haribo can be at hand at all times.
There is enough room in the frame for 33mm tyres so even though 'road' is in the name, nothing is stopping you from taking the Roadmachine past where the pavement ends. At the front, the new asymmetric fork is said to be ten per cent stiffer, while the back features the brand's dropped seat stays. The trouble, however, is the BMC sized price tag.

Giant Defy Advanced Pro 0
There is a good reason the Defy has regularly been Giant's top-selling platform since it was introduced and it just got more comfortable
Frame: Advanced-grade composite carbon | Brakes: Disc | Weight: Unpublished | Sizes: XS-XL
Since it was introduced in 2009, Giant's Defy has consistently been the brand's top-selling bike — it was also the first road bike to be offered exclusively in disc brakes. With only minor refinements to the geometry over the years, every other aspect of the bike has been improved from the D-Fuse seat post and handlebar to the oversized and tapered OverDrive 2 steerer tube.
The Defy Advanced sees an updated rear end with a slight curve in the seat stays to promote deflection. To balance out the plush rear end, Giant has adapted the D-Fuse technology for the front of the bike. The tops are now D-shaped like the seat post and Giant says the amount of flex can be customised by rotating the bar in the stem.
With these comfort features the remainder of the front triangle is robust with Giant employing its beefy Megadrive down tube and PowerCore bottom bracket shell, similar to what's seen on its race bikes. For a period in time, the Defy was the lightest frameset in Giant's range, but now made from the brand's second-tier carbon, it has gained a bit of weight.
Best aluminium road bikes
While all the top-tier bikes are made from carbon that's not to say that bikes fabricated from metal are now obsolete. Aluminium is still a fantastic material for building light and stiff bike frames and with advanced manufacturing methods, they are lighter and more comfortable than ever.
Cannondale CAAD13 Force Etap
The gold standard in aluminium road bikes
Frame: SmartForm C1 Premium Alloy | Brakes: Rim, disc | Weight: 8.5kg | Size: 44cm-62cm
Cannondale's CAAD frames have long been considered the gold standard in aluminium race bikes, and the latest iteration the CAAD13 builds on that legacy.
The geometry matches the new SuperSix Evo, and the CAAD13 retains the light steering and crisp response to pedal input. Dropped chainstays and a D-shaped seat-post greatly improve comfort, and Cannondale has used hydroforming to incorporated truncated aerofoils to help the frame slice through the wind.
The American outfit is offering the new CAAD13 in both rim and disc versions, with the latter featuring Mavic's Speed Release thru-axle dropouts. Shod with a Force eTap AXS drivetrain the bike also comes with a full carbon fork, Knot HollowGram45 carbon and wheels fender mounts galore.
Specialized Allez Sprint Disc
The budget friendly race bike with criteriums at its heart
Frame: E5 Premium Aluminum | Brakes: Rim, disc | Weight: Unpublished | Sizes: 49cm-61cm
The Specialized Allez Sprint is a high-speed cornering, criterium racing weapon. With aerodynamic D'Alusio Smartweld tubing, the sprint is supremely stiff in every way, and no watt or steering input is sacrificed to flex. This also means you can articulate granular details about the road surface based solely on the vibrations coming up through the saddle.
The frame stack is 10mm lower than the Tarmac, putting plenty of weight on the front wheel and creating steering characteristics akin to a laser-guided missile. Using D'Aluisio Smartweld tech throughout the frame, weld points are moved away from high-stress areas like the bottom bracket, requiring less material for the same amount of rigidity and strength.
Specialized offers different specs and colours depending on the region you live but for the most part, complete options are based around a Shimano 105 groupset. Should you want to choose your own spec, Specialized offers the frameset in disc- or rim-brake options.
