You’ll soon be seeking out the hilliest terrain with Ridley’s Helium C10. 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 C10 boasts Shimano Ultegra components for precision 22-speed shifting and powerful braking under all conditions. At the road are Fulcrum Racing 5 wheels for easy speed, while 4ZA's fine aluminum bars and stem, carbon seatpost, and carbon-rail saddle are light, stiff, and yield the road-damping comfort to keep you hammering the pedals day in and day out.
