For triathletes and road racers seeking superior aero performance, stable handling, and the convenience of clinchers, theres no faster all-around wheelset than the 808 Firecrest Carbon Clincher.Features:Weight: F/R 810g/920gSpoke count: 16/20Hub Used: 88/18811-speed compatible Rim Depth: 81mmBrake Track Width (center):24.73mmMax Width:27.5mmClincher Bead Width: 16.25mmCeramic Bearing: AftermarketMax Tire Pressure: 125psiMax Tire Pressure: 8.62barsDimpled SurfaceExternal NipplesGlossary:FirecrestWith 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.
