Helium

Brand: Ridley

Ridley's climber, presented as the brand's lightest bike for 2011, built around an integrated seatpost and oversized round tubes. Ridley quotes 950 g for the bare frame in 50, 40 and 30-ton high modulus carbon, with flex seatstays and carbon rear dropouts and head tube. The race geometry gives 390 mm of reach and 575 mm of stack in size M, on 405 mm chainstays. The 4ZA Helium fork is a full carbon monocoque.
