21 of the best and fastest 2020 aero road bikes — wind-cheating bikes with an extra turn of speed

The latest aero road bikes are quicker than ever before – and also more comfortable. Find out all you need to know in our complete guide to the fastest, most aerodynamic road bikes.

In just a few years aero road bikes have gone from The Next Big Thing to a mainstream bike option. The latest models have been tweaked to be faster than ever, according to the manufacturers, and to alleviate the harsh ride that characterised some early aero bikes.

  • With elongated tube shapes and other wind-cheating features, aero road bikes provide a small but handy speed boost.

  • Sleek shapes make for a distinctive look.

  • Recent aero road bikes have alleviated the harsh ride that plagued some early models, thanks to improved use of materials.

  • Frame aerodynamics is still a marginal gain; if you’re wearing flappy clothes an aero bike is a waste of money.

Aero road bikes essentially draw aerodynamic features from time trial bikes into a road frame, and balance the demands of weight and stiffness into a package that, on paper, looks to be the ideal all-round choice.

At any decent speed, most of your effort goes into overcoming air resistance, so reducing a bike’s drag means you’ll go faster, or ride at any given speed with a lower power output. Who doesn’t like the sound of that?

Most of your air resistance comes from your body rather than your bike. Wearing non-flappy clothing will help, as will losing weight. But the 20% or so of air resistance from your bike is enough for engineers and designers to focus on making road frames and products more slippery through the air. In the pro peloton aero road bikes have been quickly adopted, where the margins of victory are very slim and there has been a focus on gaining ever smaller performance gains over the years.

Weight, or the lack of it, used to be the main driving force of frame development. Along with stiffness, it was a cornerstones of bike design. These days most bikes are light, many well below the UCI’s 6.8kg weight limit (which doesn’t affect non-racers anyway), and come with more stiffness than is sometimes comfortable.

All that has made aerodynamics more important. Specialized has built its own wind tunnel, for example, and most manufacturers are testing in other facilities. Nevertheless, aero road bikes haven’t converged on a perfect, slippery shape. Different engineers prioritise different ways of improving aerodynamics but there are shared design trends: skinny, aerofoil-shaped tubes, integrated brakes, and internal cable routing.

Let’s take a look at the latest aero offerings.

Orro Venturi Ultegra Di2 Wind 400 2020 — £4,199.99

Orro has quite simply nailed it with the Venturi Ultegra Di2 Wind 400. Comfort, speed, handling, feedback and stiffness – you can have it all. And the icing on the cake? It’s a looker too!

Tester Stu Kerton says: “I’ve ridden a lot of bikes over the last 20 years (41 in 2019 alone), and while a lot of them have been very good, there are probably ten or so that really stand out as brilliant – and the Venturi is one of those.”

Why is it so good? It manages to be stiff and exciting without being harsh. “I want to feel everything that is going on from that tiny rubber footprint on the ground, and if I need to take a little bit of a battering to get that then so be it,” says Stu.

“The Venturi delivers that in spades, but the carbon lay-up used means it manages to do that while being very comfortable too, without taking anything away.”

Cannondale CAAD13 Disc 105 2020 — £1,900

The CAAD13 Disc 105 represents far more than a quick update for Cannondale’s aluminium race bike – drag has been reduced, versatility has increased and the ride is more comfortable than ever. This is a really impressive revamp and an excellent alternative to carbon.

Cannondale was, let’s be honest, slow to get on board with road bike aerodynamics. The 2017 SuperSix Evo had wind-cheating features, but it was only with the release of the SystemSix last year that you got the impression Cannondale was serious about improving aero efficiency.

The CAAD13 is in no way an aero road bike in the same vein as the SystemSix, but the designers have added several features designed to reduce drag, as they have with the SuperSix Evo on which it is broadly based. The down tube is a truncated aerofoil profile – so it has a rounded leading edge, flattish sides and a squared-off rear. The idea, as ever with a design like this, is that the air acts almost as if there were a long, tapered tail, but without the weight penalty or an adverse effect on handling.

Basso Diamante SV — £3,999.00 (frameset)

The Basso Diamante SV might be showing its age a little compared to aero road bikes launched in the last 18 months, but it’s still a real head-turner and a fine option for those who want quality Italian craftsmanship and are prepared to pay for it. Paired with the finest Campagnolo groupset and some deep carbon rims, the Diamente SV not only oozes style but, as the name suggests, it’s super-fast too.

The SV stands for Super Veloce, or ‘super fast’ in English, and is basically a more aero version of Basso’s standard Diamante frame. It has slim lines and plenty of aero-inspired features such as the blade shape to the seat tube, although the top tube maintains a more traditional rounded shape.

Look 795 Blade RS Ultegra Di2 — ~£5,600.00

The Look 795 Blade RS is all about speed, with its design focusing on stiffness and aerodynamics yet without a huge sacrifice to overall comfort. An impressive combination to achieve, and a very nice bike to ride – whether you’re racing or just out for a razz.

Look has created a bike that is ruthlessly stiff when you drop the hammer but with next to no road vibration or crass banging or rattling over rough surfaces. The 795 has a beautifully smooth ride quality similar to that of a titanium frame.

This means you can cover a good distance at speed without really noticing it, and even on four to five-hour rides I got off the bike feeling fresher than normal without realising where the time had gone.

Cannondale SystemSix — £4,000.00 – £8,500.00

If you want a true aero bike that says Cannondale on the down tube, then the carbon fibre SystemSix is the bike you want.

Cannondale claims that the “SystemSix delivers more speed, to more riders, more of the time” as a result of a frame, fork, seatpost, bar, stem and wheels that are designed to work together as a system to reduce drag. As we often point out, it’s close to impossible to assess aero claims with a wind tunnel, but what we can say is that the SystemSix is both eager to get you going and surprisingly comfortable.

Orbea Orca Aero 2020 — £2,699 – £7,499

The Orca Aero boasts lots of wind-cheating tweaks that Orbea says add up to a 27 watt advantage. Our tester David Arthur found the Orbea Orca Aero M20Team to be “a fast and great handling aerodynamic road bike with a surprising talent for smoothing out all but the roughest roads. But it is speed, not comfort, that is at the top of the list of requirements for an aero road bike, and that’s an area where the Orca Aero feels very competent. It’s right up there with the Trek Madone, Cervelo S3 and Canyon Aeroad, as super-quick aero race bikes.

“The handling is a highlight, and helps to set it apart from some aero bikes that can be exceedingly quick but a little lacking when it comes to the way they ride and translate your inputs into actions. The Orca Aero is fun and engaging, putting a smile on your face when you’re descending or chasing a friend along an undulating ridge road.”

You can customise the colour scheme and spec of your Orca Aero too, so if you want to upgrade the wheels, or have yours in pink and orange, fill your boots.

Bianchi Aria Disc 2020 — £3,500.00

The Bianchi Aria Disc is an aero road bike that offers efficiency, sharp handling and a responsive character, now with the additional all-weather assurance of disc brakes – in this case from Campagnolo.

The Aria Disc responds keenly to increased effort. Our 59cm sample wasn’t especially light at 8.5kg (18.7lb), but it felt direct when you put in the power, a meaty bottom bracket helping to keep everything solidly in place. The Aria Disc feels as manoeuvrable as the rim brake version, which isn’t a surprise given that the geometry is virtually identical. Some bikes designed for aerodynamics offer plenty of straight-line speed but they’re a little compromised when you want to flick around. The Aria Disc handles sharply, which gives you options when it comes to darting about a group or avoiding something in the road.

3T Strada — £2,650

The 3T Strada has blown us away. It’s a truly stunning bike with breathtaking speed, impressive smoothness and fine handling balance. If this is the future, as some people have speculated, we’re sold. Take our money, 3T. This is one of the most exciting road bikes available right now.

The Strada certainly won’t be for everyone. And that’s fine, there are plenty of fantastic performance road bikes currently available if the 1×11 gearing, disc brakes and tight clearances frighten you. None are as radical as the new 3T, though. What the Strada does with its unique design is offer another choice. It achieves the same aim – of being stupendously fast – but takes a different path to get there.

And if you love the Strada but are put off by the requirement to run just a single chainring, 3T has something for you: the £3,700 Strada Due will take a front derailleur so you can run conventional double-chainring gearing.

Colnago Concept — £3,499.95 (frameset)

Colnago has joined the aerodynamic arms race with the Concept, a full blooded aero race bike that is a serious step forward from the Italian company’s first aero road bike, the V1-r.

The Concept has all the capability to dice with the fastest in a race situation. Its stiff frame, deep-section wheels and lightweight give it an insatiable appetite for speed. It’s quick in all circumstances: climbs, descents, flat and undulating roads – the bike shines everywhere. This is an exciting bike to ride fast, and like all good aero road bikes it encourages you to ride flat-out.

That firm ride, and frame and fork stiffness ensure the Concept accurately follows your inputs, whether through the handlebar or pedals. It reacts positively whether you’re blasting an uphill sprint finish or bombing through a curving descent.

The Concept isn’t just for racing. It provides adequate composure and comfort, allowing you to tackle long distance rides at a few notches below race pace and not be dealt a hammer-blow to the lower back the moment the tyres encounter anything but a super-smooth surface. The front end of an aero race bike can often be overwhelmingly harsh, but the special headset and fork steerer tube that Colnago has developed mean the Concept is smoother up front than would normally be expected on an aero road bike.

Merida Reacto 2020 — £999.99 – £8,000

Merida has updated its Reacto to be, it says, lighter, more comfortable and more aerodynamically efficient than before. It has done this by slimming down the tube shapes and introducing a lower seatstay connection with the seat tube, among other things.

Merida – a Taiwanese brand although much of its engineering is undertaken in Germany – says that the new Reacto is more aerodynamically efficient than the previous version by about eight watts at 45km/h. That equates to around 5%.

Comfort has been increased through redesigning the seatstays and giving the S-Flex seatpost a slimmer cross section and a bigger ‘window’ – a notch that’s cutaway to allow more downward movement.

In 2018, Merida offered disc brake versions of the Reacto for the first time; the 2020 range, topped by the Disc 9000-E, above, features discs heavily, starting with the £2,000 Reacto Disc 4000.

Storck Aerfast Platinum — from ~£6,300

Buying the Storck Aerfast Platinum is a massive outlay, but boy, oh boy do you get one hell of a return on your investment. It’s a sub-6.5kg race weapon, with aerodynamics that work in the real world, and it offers comfort levels to challenge most endurance bikes.

Taking plenty of things it has learnt from its astonishingly good Aernario, Storck has pushed the design even further down the aerodynamics route, and what it has created in the Aerfast is a bike that’s not only unbelievably fast, but light and stiff too.

If you’re in the market for an aero bike, speed is going to be topping your list of priorities, and that’s where the Aerfast truly excels. At lower speeds the Storck feels like any other bike to ride, any other superlight bike that is, but as you ride faster it feels like a permanent tailwind is nudging you along, a friendly hand on your back as you watch the numbers climb on the Garmin – with little more effort required than there was 5mph ago. It’s a wonderful feeling, and one of which you never tire.

Cervelo S3 Disc Ultegra Di2 2020 — £5,699

Cervélo has redesigned the S3 Disc to smooth out any penalties that might occur from adding disc brakes. The result is a frame that it claims is 9% stiffer, a touch more aerodynamically efficient, and lighter by 40g compared with the regular rim brake model.

There’s a lot to like about the Cervélo S3 Disc. If you want pure speed with the reassurance of hydraulic disc brakes, it’s a very good option: it’s extremely fast and the handling is lively and direct – just what you want from a race bike – but its composure on rough roads falls some way short of its key rivals. If you’re willing to overlook its lack of comfort, it’s an explosive bike.

Ridley Noah Fast Ultegra Di2 Disc — £7,189

Aero and discs? It’s getting more common as bike makers figure out how to mount disc callipers without adversely affecting aerodynamics.

Ridley calls its collection of speed-enhancing aerodynamic features FAST. It includes a tube shape that combines an aerofoil profile with a groove that helps keep the air flowing smoothly over the surface to reduce drag. For 2019 tube shapes have been further refined, there’s a new integrated bar, stem and fork system that hides the cables completely, and the fork tips have sprouted ‘F-Wings’ to improve airflow over disc brakes.

As for the discs, Ridley believes they’re simply a better way of stopping.

Pinarello Dogma F12 — £12,000

With the ten grand psychological barrier well and truly smashed in the last couple of years, brands like Pinarello are taking off into the financial stratosphere with ultra-high-tech frames and the latest electronic shifting, in this case SRAM’s brand spanking Red eTap AXS 12-speed groupset.

Pinarello says the latest Dogma “achieves the best aerodynamic efficiency values of any Dogma model to date” and comes in two distinct versions for rim and disc brakes.

Canyon Aeroad CF SLX — £3,899-£7,249

The second-generation Aeroad CF SLX has been inspired by the work that Canyon did on its futuristic Speedmax time trial bike, with razor sharp aero tube profiles and an optional one-piece handlebar and stem. Much of the company’s focus was on reducing the Aeroad’s frontal surface area, so along with the new cockpit there’s a narrower hour-glass shaped head tube to help reduce drag. Other changes include a variant of the Trident tube shape used on the Speedmax, and a seat tube that hugs the leading edge of the rear wheel.

The Aeroad CF SLX is available in both rim brake and disc brake models.

Specialized S-Works Venge Di2 Sagan Collection Ltd — £10,250

If you’re going to fly, you need to be able to rein in that speed. Disc brakes give finer modulation of speed with less effort at the lever so as you’re whooping into Alpine hairpins you can brake later and waste less valuable speed.

As well as its aero frame, the Venge has an aero handlebar and stem. The almost complete lack of external cables further reduces drag.

Scott Foil 2020 — £3,199-£8,099

The Foil arguably kicked off the whole aero road bike trend, bringing aerodynamic design that was once the preserve of time trial bikes to regular road bikes. For 2018, Scott added disc brakes, arguing along with other manufacturers that you can go faster if you can slow down better. That’s on top of the last series of updates to the Foil that saw the down tube lowered and wrapped around the fork crown, and a smaller rear triangle and internal seat clamp in the top tube.

Don’t make the mistake of thinking this is an uncomfortable aero bike. Mathew Hayman rode over a few little bumps on his way to winning Paris-Roubaix in 2016.

Trek Madone 2020 — £4,200-£10,500

Once an all-round lightweight race bike, the Madone has had a complete aerodynamic makeover. It features a version of the Isospeed decoupler borrowed from the Domane to provide some comfort and it’s wrapped up in a frame with Kamm tail shaped tubes. Like Specialized, Trek has also developed its own brake callipers that are designed to integrate with the fork and seatstays. The head tube features flaps that open and close to accommodate the movement of the brake when the fork is turned.

For 2019 Trek introduced a hugely updated Madone road bike with adjustable IsoSpeed (a shock damper at the top tube/seat tube junction), a new geometry and disc brake models. The rim brake version is lighter while the disc brake version has no aerodynamic penalty, according to Trek..

Giant Propel Advanced SL 0 Disc 2020 — £9,999

Giant added disc brakes to the Propel Advanced lineup for 2018, claiming that the flagship model, the Propel Advanced SL Disc, has the highest stiffness-to-weight ratio of any bike in its class and a lower drag coefficient at a wider range of yaw angles than the rim brake version.

“One of the key breakthroughs is a new truncated ellipse airfoil shape – a design that lowers drag at a wider range of wind angles than traditional teardrop frame tubing,” says Giant. “Engineers also found that, with proper integration, a disc-brake design can actually improve aero performance compared to rim-brake configurations.”

As well as a stunning paint job, the top of the range Propel Advanced SL 0 Disc has a full SRAM Red AXS wireless electronic groupset and Giant’s own SLR 0 Aero Disc wheels with a 42mm deep front rim and 65mm rear.

The Propel disc range starts at £2,399 with the Propel Advanced 2 Disc.

Lapierre Aircode SL 2020 – £2,199-£4,349

French brand Lapierre gave its Aircode bikes a major update for 2018. The frame profiles were refined, and are now shaped using a combination of NACA and Kamm tail profiles. The down tube, for example, transitions from one to the other to keep drag low while increasing lateral stiffness at the bottom bracket. Other changes include a revised geometry, shorter chainstays and fork rake that has been reduced to bring it closer to the Xelius SL. There’s also a new aero seatpost, direct mount brakes and ‘TrapDoor technology’ whereby the Di2 battery is housed in the down tube for better weight distribution.

Lapierre has integrated the fork crown into the down tube to bring the front wheel closer to the frame. It’s also using a direct mount brake calliper which allows the fork crown height to be lower than with a standard brake.

Bianchi Oltre XR3 2020 – £3,700-£5,400

Bianchi took the Oltre XR2 as its starting point for the XR3’s design and then altered many of the tubes and features, resulting in a very different bike. The head tube is new, for example, the aero design fairly similar to that of the XR4, and the seat tube is new too, although it is still cut away around the leading edge of the rear wheel.

The Oltre XR3 features Bianchi’s Countervail technology, Countervail being “a patented viscoelastic carbon material with a unique fibre architecture that cancels up to 80% of vibrations while increasing the stiffness and strength of carbon frames and forks”, according to Bianchi.

The Oltre XR3 is nimble and sharp handling, and it offers a ride that’s smooth by aero road bike standards.
