808 Firecrest Carbon Tubular - The 808 changed perceptions about deep-section wheels. At first, its 82 mm-deep profile appeared only in time trials and triathlons. And sure enough, its early incarnations netted numerous Grand Tour stage wins and Ironman® world championship at Kona. Still, it didn’t take long before Zipp riders discovered that the 808’s light weight, responsiveness, and solid handing are ideally suited to hilly bike legs, criteriums, field sprints and long days off the front of the peloton.
Now, with the new Firecrest®rim shape, the 808 has improved in almost every metric. In fact, the 808 Firecrest is the fastest front wheel we’ve ever tested. Its 27.5 mm-wide profile is 15 seconds faster than before over 40 km, and now equals or exceeds the performance of any 90 mm-deep rim on the market as well as many discs. At high wind angles, the 808’s aero advantage is even greater, yet Firecrest also makes the 808 remarkably stable.
With its wider profile, the latest 808 Firecrest Tubular also shows improved lateral stiffness for efficient power transfer and crisp acceleration, yet offers greater comfort and impact resistance than its predecessor. For the 2013 model year, the 808 Firecrest is available in two decal options, the stealthy Beyond Black or the distinctive Classic White decals. Both decal options feature black anodized hubs, black spokes and black nipples.
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 - 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 (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.
Carbon Bridge - Carbon Bridge uses a Kevlar thread in a co-axial helix stitch to bind sheets of carbon to each other in our tubular rims. Because Kevlar is 350% more impact resistant than carbon, it can disperse shock more evenly throughout the carbon laminate, making for a rim that is practically bulletproof. In particular, Carbon Bridge reduces the vulnerability of the rim's tire bed, the area most susceptible to damage from impact.
Note: Zipp wheels for model year 2013 are compatible with cassettes of up to 11-speed to work with all modern drivetrains.
