The 404 Clincher 700C Front Wheel from Zipp is a classic all-rounder with strength and reliability that should make this wheel your choice wheel. It has a depth and shape that has been proven in all conditions, it’s the all-around performer and the standard by which all other wheels are measured. The 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event and situation, every triathlon distance, breakaways, field sprints and hilly finishes. The 404 Firecrest Carbon Clincher is where the Firecrest Revolution began as the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength and handling of a wider rim body. At the centre of the 404 Firecrest is Zipp’s 77 front hub with best-in-class durability and improved bearing protection with no pre-load adjustment needed. The result is improved stiffness, durability, simplicity and versatility. As well as this it includes their newly designed quick-release skewer with a wider, more ergonomic handle to provide more leverage for opening and closing. When closed, the lever contours neatly with the fork. The optimized flange geometry and spoke hole attachment pattern with Sapim CX Sprint spokes optimizes torsional and lateral stiffness and robustness. Precision-engineered hubs along with Firecrest technology create something special. Designed specifically to account for the differences in airflow patterns between clincher tyres and tubulars, the 404 Firecrest Carbon Clincher exceeds the aero performance of any other clincher wheelset in its class. As Zipp proved with the pioneering 303 Tubular, a wider rim offers greater vertical compliance for control and comfort on rough surfaces while increasing lateral stiffness for sprinting and cornering. The same holds true for Firecrest rims with clincher tyres. And because the hook beads are farther apart, the tire itself takes on a more stable shape without adding rolling resistance.
