Cervelo

S5 Red AXS Road Bike

"This S5 Red AXS is all about pure speed—Cervélo’s new front end is noticeably deeper, stiffer, and more aero than ever. The Reserve 57/64 wheels are wild in crosswinds, but super stable, and the SRAM Red AXS E1 group is as crisp as it gets. If you want a bike that’s won green jerseys and pink jerseys, this is it."

We chase every watt, and the Cervélo S5 Red AXS is our ultimate tool for the job. Cervélo’s relentless pursuit of aerodynamic supremacy is on full display, with the iconic V-stem and bayonet fork evolving for even more speed. The new S5 is over 6 watts faster and 124 grams lighter than before, yet it keeps the handling and stability we trust when the pace is on. Every detail is tuned for pro-level performance—from the co-developed Reserve 57|64 Turbulent Aero wheels that slice through crosswinds, to the SRAM Red AXS E1 wireless drivetrain that delivers instant, precise shifts. We love the “Plus-Four” HB19 cockpit, which keeps our position aero on the hoods and stable in the drops, and the fi’zi:k Antares Adaptive saddle for long-haul comfort. Whether we’re chasing a breakaway or sprinting for the finish, the S5 Red AXS is our go-to for uncompromising speed and efficiency.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
