S5 Red AXS Road Bike

The Cervelo S5 Red AXS runs SRAM's 12-speed Red AXS groupset, a 50/37T crank paired with a 10-33T cassette, on a carbon frame that Cervelo says trims over 6 watts and about 124 grams from the outgoing S5. The gains concentrate at the fork and head tube, where the one-piece HB19 bar and stem replaces the outgoing two-piece front end and tightens tolerances without adding a second set of bolts to torque. It's the lightest of the 2x builds in the lineup, with the DUB power meter built into the crank rather than bolted on.

What Our Gearhead® Experts Are Saying:

"The 10 to 33 tooth cassette on the Red AXS gives me enough range to stay seated through a punchy climb without dropping to a granny gear, then close the gap back down on the flat after. That range is what lets me commit to chasing a move instead of hesitating over whether I'll spin out or bog down."

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 Gearhead® Experts are always here to help.
