Product Description
2026 Cervélo R5 Shimano Dura-Ace Di2
Pure Performance. Unrivaled Lightness.
The 2026 Cervélo R5 Shimano Dura-Ace Di2 Carbon is a premier featherweight road bike designed specifically to master steep mountain ascents and demanding alpine stages. Built around a redesigned ultra-light carbon frameset that shaves weight while maintaining explosive stiffness, this pure climber transforms every watt of power into immediate forward acceleration. Driven by Shimano's flagship Dura-Ace Di2 12-speed electronic drivetrain with an integrated dual-sided 4iiii power meter, an ultralight Reserve 34|37 SL carbon wheelset rolling on ultra-smooth DT Swiss 180 ceramic hubs, and an integrated one-piece carbon cockpit, it offers elite racers and climbing enthusiasts an ultra-responsive, agile, and aerodynamically refined platform built to dominate high-elevation climbs.
Elite Climbing Features
Sub-UCI Lightweight Frame: Tipping the scales at a mere 651g for the frame, the R5 architecture sits well under the UCI weight threshold to deliver an exceptional power-to-weight ratio on steep ascents.
Shimano Dura-Ace Di2 Groupset: The pinnacle of electronic drivetrain technology, providing instant, precise wireless gear changes alongside superior hydraulic braking modulation.
4iiii Precision Pro Power Meter: Comes equipped from the factory with a Gen3+ dual-sided power meter for clinical-grade performance metrics and effort management.
Reserve 34 | 37 SL Wheelset: Superlight carbon rims laced to DT Swiss 180 hubs with ceramic bearings, engineered for rapid acceleration and effortless handling in crosswinds.
HB18 Carbon Cockpit: An integrated single-piece bar and stem design that trims 150 grams of weight while yielding a 2-Watt aerodynamic drag reduction at the front end.

Legacy of Excellence
The Cervélo R5 has defined the standard for professional road bikes for over two decades. This 2026 iteration is more than just a bike for the mountains; it is a versatile racer that remains UCI-legal in its geometry while pushing the boundaries of component integration. With 34mm of tire clearance and the aerodynamic efficiency of the HB18 cockpit, the R5 is as comfortable on long, high-speed group rides as it is attacking the Mont Ventoux. This is the ultimate tool for those who refuse to settle for anything less than the pinnacle of road cycling technology.
