Zipp 808/404 Combo Tubular wheelset, Zipp 808 rear wheel to optimize aerodynamics, Zipp 404 front wheel to maximize control. Perfect for road and triathlon use in flat or hilly with windy conditions where one does not want to sacrifice control while maintaining optimal aerodynamics. Using Zipp 808/404 combo will help you preserve bike handling control.

Technology: Zipp exclusive Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on 808 rims, the 808 provides the speed you need to win. 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 uses a Kevlar thread in a co-axial helix stitch to bind sheets of carbon to each other in Zipp 808/404 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.

Zipp 808 Rear wheel is an 81mm rim profile designed for triathletes and road racers. Manufactured with a fully toroidal shape inspired by the 1080. At 30mph, the current 808 saves up to 7 watts. Zipp 808 rear wheel weight 808g; 20 spokes count.

Zipp 404 Front wheel is an 58mm rim profile that has benefited from the new toroidal shapes. These subtle changes have reduced drag at every angle in Zipp test range while taking stiffness and braking performance to new levels. Weight 582g, aero rim Width 24.00mm, and 16 Spokes Count.
