Product Description
2026 Cervélo R5 SRAM RED AXS
The Gold Standard of Climbing Bikes. Pure Performance at 5.97kg.
The 2026 Cervélo R5 SRAM RED AXS Carbon is the ultimate lightweight climbing machine, crafted for competitive cyclists who accept no compromises when every gram matters on steep inclines. Built around an astonishingly light carbon chassis that pairs a 651g frame with a 298g fork, this flagship road racer delivers unyielding bottom-bracket stiffness for instant acceleration out of the saddle. Driven by SRAM's pinnacle RED AXS E1 12-speed wireless electronic groupset with an integrated power meter, a smooth ceramic bottom bracket, sub-1300g Reserve 34|37 SL carbon wheels on DT Swiss 180 ceramic hubs, and an integrated one-piece carbon cockpit, it provides an ultra-responsive, streamlined, and world-class performance platform designed to conquer high-altitude mountain passes and carve down technical descents.
Elite Lightweight Features
Ultralight Frame Engineering: Tipping the scales at a mere 651g for the frame and 298g for the fork, every carbon layup detail has been optimized to construct the ultimate climbing weapon.
SRAM RED AXS Drivetrain: The pinnacle of wireless 12-speed shifting technology, featuring an integrated power meter and a ceramic bottom bracket to ensure maximum mechanical power transfer.
Reserve 34 | 37 SL Wheelset: Built around ultra-smooth DT Swiss 180 ceramic hubs, these carbon rims shave 60g compared to previous generations while maintaining pro-tier lateral stiffness.
HB18 Integrated Cockpit: A sleek, single-piece carbon handlebar and stem system that trims 150g of weight while enhancing front-end aerodynamics by 2 Watts.
Race-Ready Geometry: Engineered for razor-sharp handling with frame space for up to 34mm tires, offering superior cornering traction and compliance on high-speed descents.
