Gravel
Ridley Kanzo Fast
2025 · 700c wheels · 5 sizes
First-generation Kanzo Fast, Ridley's aero carbon gravel race frame with a 1x-only drivetrain and clearance for 42 mm tyres. Geometry is from Ridley's frame passport for the identical Invenio Gravel Carbon frame. Ridley's own website lists the XL seat angle as 73 degrees and the passport as 72.5; the 72.5 figure is used here because it matches the published top tube. Standover heights come from Ridley's website table, as the passport's figures for that dimension are implausibly high. Components listed are from the Shimano GRX800 1x12 build, which uses a one-piece integrated bar and stem.
