Our Tour de France bikes

We’ve all had a fantastic time watching this year’s Tour de France: the riding, the incredible performances, the stunning scenery, the gear, the tech and of course the bikes.

These 2018 models are three of our favourites:

Specialized Tarmac – Teams Bora–Hansgrohe & Quick-Step Floors

The new Tarmac SL6 is the sixth generation model, with a frame 200g lighter than its predecessor the Tarmac SL5. The SL6 has a far more complex carbon layup than the previous Tarmac frame, with the number of pieces of carbon used to construct a frame rising from 350 to 500, reducing the overlaps between each carbon ply and resulting in the lower frame weight. The new model also uses three new forks across the size range. Each fork uses a 1.5in lower bearing, reducing any harsh angles of carbon fibre flowing from the fork crown to the steerer tube, and the taper of the steerer tube is different depending on the stiffness requirements. It’s also more aerodynamic, thanks to the company’s own Win-Tunnel which was used in the development of the new frameset and is set up to perform exceptionally when climbing and sprinting. There is also a revised geometry utilising Retul and professional rider input and Tarmac has developed overlapping geometries that serve riders regardless of their gender.

Argon 18 Gallium Pro – Team Astana

This is the bike that powered Fabian Aru to his stage win and briefly take the yellow jersey off the hands of Team Sky. The frame is incredibly light, weighing approx 794g. Other frame updates include a new 27.2 seatpost for added compliance and the frame can now accommodate 28mm tyres. The company’s 3D headset technology means there are three different head tube sizes available at every frame size, along with additional spacers.

Orbea Orca Aero – Cofidis

This aero bike offers 3:1 tube profiles to provide deeper sections. Amongst changes made has been a deeper section to the forks, which Orbea says saves 4 Watts or 8.4 seconds over 50km. The frame also receives updates, with more elongated tube shapes and abbreviated trailing edges to help increase stiffness and smooth out drag, even at slow speeds. There’s an aero seat post and the cockpit contains an integrated stem and handlebar to cut through the wind, with a larger, semi-integrated crown for added stiffness. The frame has internal cable-routing options for mechanical, wireless or electronic shifting, along with three mounting holes per bottle cage for versatility.
