Overview
About this bike
As light and fast as the name sounds, Ridley’s Helium C20 is a head-turner. Unwavering attention to detail results in mystical lightness, massive power transfer, and everlasting comfort. With Ridley's high modulus carbon tapered tube shapes, asymmetrical, oversize chainstays, and a power-channeling BB30 bottom bracket, every ounce of energy is delivered to slay the hills. Just as important—less overall material means you’ll go up them with less effort. Plus, the Helium’s slender, vibration-damping chainstays provide comfort and lateral stability, and the tapered head tube ensures Jedi-like cornering prowess. The C20 is built with Shimano’s 105 components for precision 22-speed shifting and powerful braking in all conditions. At the road, Fulcrum’s Racing 7 wheelset gets up to speed with ease, while the fine 4ZA aluminum bars and stem, carbon seatpost, and carbon-rail saddle are light, stiff, and yield the road-damping comfort needed to keep you hammering the pedals day in and day out.
