The RED E1 crankset is a top tier road component designed for riders who demand efficiency and precise fit. An optimized carbon layup significantly reduces weight in the hollow crank arms while maintaining outstanding stiffness. X Range gearing minimizes cadence changes during front shifts, allowing smooth and consistent power transfer. The design follows modern bike fitting standards and offers a broad selection of crank lengths.
