808 Firecrest? Carbon Clincher Rearwheel
Optimizing wheels to perform with precision and control at the depth of the Zipp808 Firecrest? Carbon Clincher is pure engineering science.
Pure engineering science: the 808 Firecrest??Carbon Clincher Wheel from Zipp While the 808 Firecrest?s aerodynamics and stability are proven every weekend in road races, triathlons and time trials around the world, understanding how profoundly good these wheels are only comes from riding the wheel that, as a set, has proven faster than any other.
Optimizing the revolutionary Firecrest aero-rim concept for an 82mm depth and the distinct airflow pattern of clincher tires required us to evaluate a slew of minutely varied prototypes through CFD, or computational fluid dynamics, software and in the wind tunnel. At 27.5mm wide, the final version is the fastest deep-section carbon clincher in the world. Yet, with a weight of only 1,885grams, it more than holds its own on the climbs. With Firecrest?s unparalleled approach to the wheel?s center 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 Firecrest 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.
At the center of the 808 Firecrest Carbon Clincher is Zipp?s 77/177 hubset with best-in-class durability and improved bearing protection with no pre-load adjustment needed. The result is improved stiffness, durability, simplicity and versatility: Features – 808 Firecrest??Carbon Clincher Rearwheel Improved 82mm rim profile ? the fastest Firecrest wheel, still extremely stable ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel Industry leading Showstopper brake track: powerful and consistent braking, even on the wet 77/177 hubset, reliable & durable, proven in the Spring Classics.

Showstopper? is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin. Showstopper? is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. In order to improve this for the wettest of rides, we have introduced a molded-in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge (relative to the rotation of the wheel) of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions. Beneath the textured brake track are SiC particles suspended in the resin. Silicon Carbide is nearly three times harder than hardened steel and is very abrasion resistant. Commonly used in cutting tools and grinding wheels, the SiC particles in our Showstopper? brake track ensure consistent performance for the life of your wheel. The net result is equal brake force in wet conditions when compared to industry leading aluminum rims. Showstopper technology delivers greater stopping power in wet conditions than any carbon wheel ever produced.
Firecrest? With the proprietary Firecrest rim shape in our 202, 303, 404 and 808 Firecrest wheels, 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 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 all of our carbon rims. ABLC smoothes airflow across the rim’s surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four 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.
