Zipp 404 Firecrest Carbon Clincher Black Front Bicycle Wheel Size 700c

ALL AROUND ADVANCEMENT If you had to choose just one wheel, the Zipp 404 Firecrest Carbon Clincher Bicycle Wheel should be your choice. With the depth and shape proven in all conditions, it's the all around performer and the standard by which all other wheels are measured. Its 58mm rim depth is a classic all around performer that has carried athletes to victory in every kind of event and situation every triathlon distance, breakaways, field sprints and hilly finishes. The 404 Firecrest Carbon Clincher is where the Firecrest Revolution began as the first deep profile carbon clincher design to offer the superior aerodynamics, ride quality, strength and handling of a wider rim body. Yet the 404 Firecrest Carbon Clincher weighs 1,690 grams per wheelset, providing best in class performance at a light weight. FEATURES Firecrest Firecrest more aerodynamic than any other rim design and it improves handling in crosswinds and overall ride quality. Carbon Clincher This is the culmination of two years of intensive prototyping and testing. It is an exclusive heat resistant resin based on the materials used in motorsports brake systems and it improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards. ABLCtm Aerodynamic Boundary Layer Control The patented and instantly recognizable dimpled pattern found on all Zipp carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model. The third generation of ABLC has up to four times more dimples than before. VCLCtm Visco Elastic Constrained Layer Control 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. Wire EDM Electron Discharge Machining allows Zipp to cut the materials for the rear hub drive internals after they've been hardened through heat treating, negating the warping and imprecision caused by the heat treating process. Steel Bearings Zipp is the only company specifying Swiss made highly specialized ball bearing cartridges. Zipp wheels feature a superior level of bearing smoothness and long life. Zipp ball bearings are specified to 10 millionths of an inch tolerance, guaranteeing that they are at least 2.5 times rounder and better matched than most company's high precision balls, and more than five times tighter than most precision balls. Includes Zipp's 77 hub, built with best in class durability and improved bearing protection with no pre load adjustment needed. The result is improved stiffness, durability, simplicity and versatility Stealthy Matte Black decal option Comes with Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve core wrench, rim tape and quick release.
