Product Description
2026 Cervélo R5 SRAM RED XPLR AXS 1
Uncompromising Lightness Meets 13-Speed Precision.
The 2026 Cervélo R5 SRAM RED XPLR AXS 1 Carbon is a groundbreaking, sub-6kg lightweight road machine engineered for pure climbing performance and progressive 1x efficiency. Built around Cervélo's featherweight carbon chassis, this ultra-lightweight road racer eliminates the front derailleur entirely to maximize aerodynamic efficiency and drop system weight to an astonishing 5.97kg. Driven by SRAM's pinnacle 13-speed RED XPLR AXS wireless drivetrain with an expansive 10-46T gear range and integrated power meter, Reserve 34|37 SL carbon wheels spinning on ultra-smooth DT Swiss 180 ceramic hubs, and an integrated one-piece carbon cockpit, it offers climbers and elite road cyclists an hyper-responsive, sub-UCI platform tailored for explosive alpine accelerations and high-speed efficiency.
Elite Lightweight & Performance Features
Sub-UCI Weight Profile: Tipping the scales at a mere 5.97kg (size 56), the R5 architecture sits an incredible 900 grams below the UCI weight floor to maximize power-to-weight performance on steep ascents.
SRAM RED XPLR AXS 13-Speed Drivetrain: Utilizes cutting-edge E1 wireless single-ring technology paired with a wide-range 10-46T cassette, delivering smooth gear progression and an expansive ratio range without front derailleur drag.
Reserve 34 | 37 SL Wheel System: Features an updated ultralight carbon rim construction laced to DT Swiss 180 ceramic hubs, trimming 60g while preserving exceptional rotational stiffness and speed.
HB18 Integrated Carbon Cockpit: A seamless single-piece handlebar and stem system that shaves 150g from the front end while providing a 2-Watt aerodynamic drag reduction.
Modern Chassis Versatility: Combines race-proven handling geometry with expanded clearance for up to 34mm tires, ensuring superior traction, compliance, and control on unpredictable road surfaces.
