Ridley Helium Disc
2022 · 700c wheels · 6 sizes
Lightweight disc-brake carbon climbing bike from Ridley's Essential Series, with round-looking but slightly oval tubes, a D-shaped steerer that hides the front cables, and clearance for 28 mm tyres. Ridley no longer lists it as a current platform, so these are run-out models. Ridley publishes a 45 mm fork rake for every size.
