Nearly every major bike brand now offers at least one aero road bike in various different builds, and here are some of the slipperiest contenders of 2019.
The all-new Venge is said to be lighter, faster and better handling than the previous version — of course. It's available only with disc brakes and electronic gears, so there's no such thing as a budget Venge.
Ridley's top-level aero road bike features an integrated fork and seat clamp and F-Wings behind the fork dropouts that are designed to reduce turbulence and therefore minimise drag.
Canada's Argon 18 introduced the Nitrogen in 2014 but the Nitrogen Disc is brand new. The disc model is said to offer greater torsional rigidity as well as plenty of ergonomic adjustability and clearance for tyres up to 30mm wide.
Wilier Cento10Pro £4,399.99-£7,999.99
The new Cento10Pro is an evolution of the existing Cento10Air but with disc brake options as well as rim brakes and a 6% increase in torsional stiffness, according to Wilier. The frame and fork profiles are based to NACA airfoil shapes with truncated tails allowing Wilier to save weight and increase stiffness.
Look 795 Blade RS £TBC
Look says that its new aero bike, available in both rim brake and disc brake versions, offers a 5% aerodynamic advantage over its predecessor. Look also claims the fork, rear triangle and head tube have been made stiffer, and the new bridge-less 'Smooth Sword' seatstays are designed to bend slightly under compression, allowing the rear wheel to maintain consistent contact with the road.
BMC was one of several big brands to reveal a new aero road bike back in July. The new version of the Timemachine is designed solely around disc brakes and features integrated storage and a water bottle design that minimises drag at wider yaw angles.
The Strada aero road bike was initially designed for a single chainring drivetrain but 3T has now added the Strada Due to the lineup, giving you the option of fitting an electronic groupset with a double chainring.
The Orca Aero Disc features a huge down tube with a double radius profile and flattened sides that Orbea says improves airflow at higher yaw angles, and there's a wide gap between the fork legs that’s said to reduce airflow pressure.
The Colnago Concept frameset, available in both rim brake or disc brake versions, puts in superb performance out on the road, offering awesome speed, fine handling and real-world usability.
Lapierre Aircode SL £2,199-£6,199
The Aircode SL, available only with rim brakes, has taken many of its design cues from Lapierre's Aerostorm time trial bike, using both NACA and Kamm Tail tube profiles to reduce drag. Lapierre has reduced the frontal area by integrating the fork crown into the down tube.
Felt AR 5 £2,299
Felt's AR bikes feature a rear brake that's mounted under the chainstays and a narrow 'Twin Tail' bridgeless seatstay design. You also get a reversible seatpost that allows you to steepen the seat angle for time trialling.
Storck's Aerfast is a truly awesome race bike. As well as having strong aero credentials, it's fast, light and stiff while offering comfort levels that challenge those of most endurance bikes.
Italy's Kuota offers the Kryon in both rim brake and disc brake models. You get a “vibe damper system” incorporated into the seatpost area to smooth the ride; two separate dampers can be specced, depending on your weight.
Tifosi Auriga £1,999.99-£2,499.99
On the latest version of its Auriga aero road bike, Tifosi has moved the rear brake from behind the bottom bracket to the seatstays in order to avoid mud and water and maximise power. Whereas the rim brake model will accept tyres up to 25mm, the disc brake version can take 28s.
