Cervelo built the S5 Red AXS around a reworked carbon frame that trims drag and weight from the outgoing S5, with the biggest gains concentrated at the fork and head tube. SRAM's Red AXS groupset brings a wide 10 to 33 tooth cassette and a crank-integrated power meter to the build, so shifting range and data collection are handled without bolt-on accessories. The one-piece bar and stem carries that same aero focus into the front end, cutting bulk without adding extra hardware to dial in fit. What Our Gearhead(R) Experts Are Saying:"Sitting in a fast-moving group, the Red AXS cassette gives me a gear for every surge without ever feeling like I'm caught between two ratios. I can match the pace change the moment it happens instead of hunting for the right gear a beat behind."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.
