The 2025-2026 Cervélo R5 is built for riders who want top-tier climbing performance in an ultra-lightweight package. With a frame weight of just 651g and a complete SRAM Red build tipping the scales at only 5.97kg (size 56), it comes in well under the UCI’s minimum weight limit. Cervélo has refined every in-house component, trimming a total of 326g from the previous model without compromising stiffness or ride quality.

Geometry updates keep the handling quick and familiar, with a revised fit that now mirrors the S5 for better rider positioning. The all-new HB18 bar and stem not only improve aerodynamics but also save nearly 150 grams, combining stiffness and comfort for long climbs or aggressive racing. More size combinations are now available to help riders achieve their ideal fit, and at Tri Town, we offer a complimentary bike fit with every R5 or S5 purchase—including a no-cost bar and stem swap within 60 days.

The new Reserve 34 | 37 SL wheelset, designed specifically for the R5, drops an additional 60g while maintaining strength and responsiveness. Like all Cervélo bikes and Reserve wheels, the R5 is backed by a lifetime manufacturer’s warranty, so you can ride and race with confidence.
