The 808 Clincher 700C Front Wheel from Zipp has been optimized to perform with precision and control at the depth of the 808 rims. The 808's aerodynamics and stability are proven every weekend in road races, triathlons and time trials around the world, but understanding how good these wheels are only coming from riding the wheel to show how much faster this wheel really is. Optimizing the revolutionary Firecrest aero-rim concept for an 82mm depth and the distinct airflow pattern of clincher tires required Zipp to evaluate prototypes using CFD (computational fluid dynamics) software and the wind tunnel. At 27.5 mm wide, the final version is the fastest deep-section carbon clincher in the world. Yet, with a weight of only 855g, it more than holds its own on the climbs.
With Firecrest's unparalleled approach to the wheel's centre of pressure, the 808 Firecrest Carbon Clincher also handles crosswinds with the stability you'd normally associate with a much shallower rim - making the 808 Carbon Clincher ideal for non-disc-legal courses like Kona. Plus, the wide rim shape provides efficient power transfer along with comfort and durability, making it an excellent choice for just about any terrain and riding style. This rim is built onto Zipp's 77 hub which features best-in-class durability and improved bearing protection with no pre-load adjustment needed. The result is improved stiffness, durability, simplicity and versatility.
The optimized flange geometry and spoke hole attachment pattern with Sapim CX Sprint spokes to optimize torsional and lateral stiffness and robustness. In addition to Firecrest, all Zipp full-Carbon Clinchers feature an exclusive heat-resistant resin as part of the composite structure. Utilized in the 808 Firecrest Carbon Clincher, this technology prevents spikes in rim temperature and tire pressure that can impact performance and handling. Zipp Carbon Clinchers have never had a heat-related failure. So, every rider can tackle even the longest, most technical descents with confidence. For triathletes and road racers seeking superior aero performance, stable handling, and the convenience of clinchers, there's no faster all-around wheelset than the 808 Firecrest Carbon Clincher.
