Cervelo R5 Red AXS (2026)

Key Features of the Cervelo R5 2026

• Massive weight saving — the new R5 (size 56) builds up to just 5.97 kg, with frame + fork weighing only 651 g + 298 g. That’s around 100 g lighter for frame/fork plus a total ~326 g weight reduction across all Cervélo components.
• All‑new integrated cockpit — the new one‑piece HB18 handlebar/stem combo replaces the old separate bar + stem, cutting nearly 150 g and improving aerodynamics.
• Updated wheelset: Reserve 34 | 37 TA (Turbulent Aero) — lighter, custom‑laid carbon wheels optimised for real‑world wind conditions and enhancing overall weight and aero efficiency.
• Geometry and fit aligned with aero sibling — fit geometry now matches that of the aero‑focused Cervélo S5, making transitions between models smoother for riders who use both.
