Ridley Astr
2026 · 700c wheels · 5 sizes
Carbon race gravel frame sold as the Astr RS (Elite series) and the Astr (Essential series), which share one geometry. Tyre clearance is 52 mm with a 1x drivetrain and 47 mm with 2x, and the fork has 50 mm of rake. Ridley's frame passport PDF differs from its website table in three cells (M top tube 571, M wheelbase 1044, L wheelbase 1084); the website values shown here are the ones that agree with the rest of the geometry.
