The Cervélo R5 is a climbing-focused road bike built around a 651 g frame and 298 g fork in size 56, with a complete build claimed at 5.97 kg — roughly 900 g under the UCI weight minimum. It pairs Shimano's 12-speed Ultegra Di2 groupset with a one-piece HB18 carbon bar and stem and Reserve 34|37 SL wheels made for this frame. The race geometry matches the aero S5, so it handles like a race bike while giving up some drag to dedicated aero frames. It suits riders who prioritize low weight and climbing over flat-road speed, and it comes with a dual-sided 4iiii power meter.

The Cervélo R5 Ultegra Di2 is a road bike with an all-carbon frame and an all-carbon tapered fork. It builds up to 5.97 kg in size 56, which is 900 g under the UCI minimum weight limit. The frame weighs 651 g and the fork weighs 298 g, both in size 56.
The fit geometry is race-ready and matches the S5. A one-piece HB18 carbon bar and stem saves nearly 150 g and makes the bike two watts more aerodynamic than the previous R5. Reserve 34|37 SL wheels, designed specifically for the R5, save another 60 g.
It is equipped with a Shimano Ultegra Di2 12-speed drivetrain, with a 52/36T crankset and an 11-34T cassette.
