Cervelo claims its new S5 is the fastest aero bike in the pro peloton and Jonas Vingegaard will look to prove it at this year’s Tour de France

Last month, we spotted Jonas Vingegaard aboard what appeared to be a new, unreleased Cervelo S5 at the Critérium du Dauphiné, speculating the bike was undergoing final testing ahead of the Tour de France. It seems we were correct, as the Cervelo S5’s official launch has coincided with the opening week of La Grande Boucle.

While it looks remarkably similar to the outgoing model, Cervelo reckons the new S5 is even faster than before, thanks to “evolving the front end, and going on a bit of a diet, making it an even more potent partner for the fastest riders in the world.”

Cyclingnews’ senior tech writer, Will Jones, managed to spend some time with Vingegaard’s new Cervelo S5 at the team hotel in Lille ahead of Stage 1, so make sure to check it out.

Many of the new design changes stem from growing trends we’ve observed in the aero bike category over the past year, the most notable proponents being the Ridley Noah Fast 3.0 and the Factor prototype ridden by Jake Stewart. That’s not to say the outgoing S5 is obsolete by any stretch; after all, it came out on top in our wind tunnel testing at zero yaw, but Cervelo claims the new model is six watts faster than the outgoing version.
