The S5 Red AXS is built for outright speed with real-world race results to match. A deeper front end and fully integrated HB19 cockpit deliver the aero edge, while the co-developed Reserve 57|64 wheels complete the system. It’s faster, lighter, and retains the planted stability riders love — ideal for sprints, breakaways and fast group rides.

Why we rate it

• Iconic V-stem and deeper fork/head tube profiles for proven aero gains.
• Reserve 57|64 Turbulent Aero wheels for speed in real wind, not just the tunnel.
• SRAM Red AXS 12-speed with integrated power meter for precision and data.
• Lighter overall build while keeping S5 stability at speed.
