Cervelo

R5 Ultegra Di2 Road Bike

What Our Gearhead® Experts Are Saying:

“The Ultegra Di2 build hits a sweet spot for riders who want elite performance without stepping into flagship pricing. The drivetrain stays consistent even on long, steep climbs, and the Reserve wheels keep the bike feeling lively without sacrificing control. It’s a setup I’d trust for big mountain days and high-mileage training alike.”

The R5 Ultegra Di2 delivers Cervélo’s legendary climbing pedigree in a balanced, race-ready configuration. At the heart of the bike is a 651g carbon frame paired with an all-carbon tapered fork, engineered to provide exceptional stiffness under acceleration while maintaining predictable handling at speed. The integrated HB18 carbon bar and stem reduce system weight and improve front-end rigidity, contributing to the bike’s efficient climbing character.

Shimano’s Ultegra Di2 R8170 drivetrain anchors this build with precise 12-speed electronic shifting and reliable hydraulic braking. The 52/36T crankset paired with an 11–34T cassette provides a versatile gear range suited to sustained alpine climbs and rolling terrain. Reserve’s carbon wheelset offers a lightweight, tubeless-ready platform that enhances responsiveness without compromising descending confidence.

Designed for riders who prioritize climbing efficiency, control, and long-distance performance, the R5 Ultegra Di2 excels on high-elevation routes, endurance rides, and race-day mountain stages where low weight and predictable handling make the difference.
