2012 Zipp 808 Firecrest Carbon Clincher Rear Wheel Beyond Black

Beyond Black features black anodized hubs, black spokes, and black decals. To achieve maximum performance with every Zipp wheelset, our engineers create uniquely tuned rim profiles for every combination of rim depth and tire style. So the process of developing the all-new 808 Carbon Clincher was much more complex than merely adding clincher sidewalls to the 808 Tubular or increasing the depth of the 404 Carbon Clincher.

Firecrest RevolutionOptimizing the revolutionary Firecrest aero rim concept for a 81mm depth and the distinct airflow pattern of clincher tires required us to evaluate a slew of minutely varied prototypes through computational fluid dynamics and in the wind tunnel. At 27mm wide, the final version is the fastest deep-section carbon clincher in the world. Yet, with a weight of only 1759 grams, it more than holds its own on the climbs.

With Firecrest’s unparalleled approach to the wheel’s center of pressure, the 808 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.

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 Carbon Clincher, this technology prevents spikes in rim temperature and tire pressure that can impact performance and handling. In fact, heat dissipation is improved so substantially that ours are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options. 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 Carbon Clincher.
