An unreleased Cervelo R5: Matteo Jorgenson's Tour de France bike is a weight weenie's dream
Briefly

The Cervélo R5 climbing bike weighs exactly 6.8kg, which conforms to UCI regulations. It features enhancements aimed at performance during steep climbs, as acceleration is highlighted as essential for success. Design modifications include a sculpted transition from fork crown to frame, a switch to a direct mount brake system, and a stiffer rear end for improved handling. Adjustments in fit align with the S5 aero bike to allow seamless transitions for riders. Additionally, components like the seatpost and saddle cradle have been redesigned for weight reduction, emphasizing strategic material choices and design efficiencies.
The new Cervélo R5 climbing bike weighs precisely 6.8kg, meeting UCI weight limits, and will be used by Team Visma auf steeper terrains where acceleration is crucial.
The transition from the fork crown to frame has been streamlined to eliminate excess weight, while the brake mount has been switched to a direct mount system to shave grams.
A stiffer rear end has been achieved by slightly raising the top tube, aligning the fit with the S5 aero bike for smooth rider transitions between both.
The seatpost design remains similar but lighter, featuring a new clamp that reduces weight, and even the saddle cradle has shifted from alloy to carbon for further weight savings.
