The 404 S has been developed for ambitious road cyclists who want to benefit from modern aerodynamics and high efficiency. The rim shape, inspired by Firecrest wheels, improves airflow and ensures confident handling even in challenging wind conditions. Thanks to the wide rim design, modern tyres can be ridden at lower pressures, optimising comfort, grip and rolling performance. High-quality Sapim CX-Sprint spokes and the tried-and-tested 76D/176D hub technology ensure direct power transfer and reliable durability.
