The Cervélo S5 Red XPLR AXS 1 Road Bike remains a leading example of speed and aerodynamic precision, proven by standout performances like Wout van Aert’s historic Green Jersey win and Simon Yates’ maglia rosa achievement.

Building on this legacy, the latest S5 is over 6 Watts faster and 124 grams lighter than the previous model, while maintaining the handling and stability riders expect.

Key aerodynamic improvements focus on the front end, with deeper fork legs and head tube, alongside a redesigned one-piece handlebar/stem that enhances the original V-stem design. The new Reserve 57|64 Turbulent Aero wheels, co-developed with Reserve, perfectly complement the frame’s aerodynamic profile.

KEY FEATURES

• Aero Aero Aero
  The new S5 is 6.3 Watts faster than its predecessor. These gains are realized primarily at the front end of the bike, but the integration of the asymmetric profiles of the seat tube and rear wheel are a significant source as well. Cervélo has long been the aerodynamic leader in the peloton, and are confident that the new S5 is at least 5 Watts faster than the bikes of competitors.
• One-Piece Handlebar/Stem
  HB19 uses the “Plus-Four” concept, meaning the dimension at the hoods is 4cm narrower than in the drops (e.g. 38cm/42cm). This approach helps riders maintain a more aero body position while their hands are on the hoods, and provides stability in the drops for descending and sprinting. All bar sizes are UCI-legal, even in light of the most recent regulations change.
• Not just faster. Lighter, too.
  Despite an increase in surface area, the new S5 is 124 grams lighter than its predecessor. While the increase in fork and head tube depth added weight, we optimized the layup and hardware to make the system lighter.
• Reserve 57|64 - Designed for S5:
  The new Reserve 57|64 wheelset was co-developed by Reserve and Cervélo, and designed for use in the new S5. The rear wheel’s asymmetry matches the seat tube, ensuring air flows smoothly over both. The new wheelset is 3 Watts faster than the 52|63 wheels, and weighs the same.

• ONE PEACE OF MIND
  The new S5’s one-piece bar and stem is a big part of the bike’s increase in aerodynamic performance, but aerodynamic improvements are limited if the bike doesn’t fit you perfectly. They made nine different size combinations, and when you buy an S5, Billy Bilsland Cyles will help you get the right bar/stem combo, for no additional cost.
