TheCervelo R5 Ultegra DI2 2026 bikewe’re featuring here at Escapa is a road bike built for long days in the mountains, attacks on steep climbs, and descents where precision makes all the difference. This new generation combines exceptionally low weight with the stiffness needed to accelerate powerfully and transfer every watt efficiently.
A climber that also knows how to descend
A mountain bike can’t just be lightweight. It must also hold its line, inspire confidence, and respond precisely when entering technical turns or tackling fast descents.
The R5’s handling geometry retains the balanced character of the previous generation, with minor adjustments to accommodate 29mm tires. The result is a predictable and stable ride, capable of maintaining the agility needed on climbs and the confidence required on mountain descents.
The 410mm chainstays enhance its responsiveness during accelerations, while the 57.3mm Trail remains consistent across the entire size range to provide a consistent ride for every rider.
Updated Riding Position for Greater Performance
Cervélo has revised the riding position to bring it closer to the S5’s tuning geometry. This evolution allows for a more efficient riding position in Rapido groups and facilitates the transition between the two models for riders and teams who alternate between a climbing bike and an aero bike.
The R5 retains its identity as a mountain bike but now offers a more competitive riding position optimized for riding fast on any type of course.
New HB18 Cockpit
The integrated Cervélo HB18 Cockpit accounts for a significant portion of the weight savings on the new R5. Its construction reduces weight by approximately 150 grams compared to the previous design and improves the bike’s aerodynamic efficiency by about 2 watts.
Its design draws on insights gained during the development of the S5’s handlebars, combining:
- Stiffness for sprints and changes in pace.
- Ergonomics for long rides.
- Clean cable integration.
- Aerodynamic improvements.
- Compliance with current UCI regulations.
Reserve 34|37 SL Wheels
The new Reserve 34|37 SL wheels have been specifically developed to complement the R5’s climbing and all-around capabilities. Their distinctive profile combines a 34 mm front rim with a 37 mm rear rim, aiming to balance lightness, handling, responsiveness, and aerodynamic efficiency.
The revised carbon layup saves approximately 60 grams compared to the previous generation without compromising the stiffness or strength of the wheelset. The wheels are paired with Dt Swiss 240 hubs.
Cervélo R5 Ultegra Di2
This version is equipped with a 12-speed Shimano Ultegra Di2 groupset, a power meter, 52/36T chainrings, and an 11-34T cassette.
It uses Reserve 34|37TA wheels with Dt Swiss 240 hubs and has a claimed weight of approximately 6.43 kg
