Zipp 808 Firecrest Carbon Clincher
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.
Optimizing 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 centre 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.

Technology in the Zipp 808 Firecrest Carbon Clincher
Firecrest
With the new Firecrest rim shape in our 404 and 808 Tubulars and Carbon Clinchers, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds, wheel strength, and overall ride quality.
ABLC (Aerodynamic Boundary Layer Control)
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most of our rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up to 4 times more dimples than before.
VCLC (Visco-Elastic Constrained Layer Control)
Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration.
