Zipp 404/808 Firecrest Mixed-Depth Wheelset Package

The Ultimate Aerodynamic Advantage – Race-Ready, Right Out of the Box

Elevate your performance with this meticulously curated wheelset package that combines the legendary speed of Zipp's Firecrest technology with premium components chosen by our pro mechanics. This mixed-depth configuration delivers the perfect balance of aerodynamic efficiency and real-world handling that championship triathletes and time trialists demand.

The Configuration That Wins Races

Front: Zipp 404 Firecrest (58mm) The 404 Firecrest front wheel provides the ideal compromise between aerodynamic performance and crosswind stability. Its 58mm rim depth cuts through the air while maintaining predictable handling when the wind picks up – giving you the confidence to stay in your aero position when it matters most.

Rear: Zipp 808 Firecrest (82mm) The deeper 808 Firecrest rear wheel maximizes your aerodynamic gains where handling is less affected by crosswinds. This 82mm profile delivers free speed on every pedal stroke, helping you maintain higher velocities with less effort over long distances.

Complete Performance Package Includes:

Continental Grand Prix 5000 – A Race Day Standard Pre-mounted on Zipp carbon wheels, the Continental Grand Prix 5000 is one of the most proven and trusted tires in road and triathlon racing. Renowned for its exceptionally low rolling resistance, superior cornering grip, and reliable puncture protection via Continental's BlackBelt technology, the GP5000 is a tire that performs when it matters most. Paired with Zipp's wide-rim Firecrest profile, the tire sits at an optimal width that enhances both aerodynamics and ride quality, giving you a complete, race-ready wheelset right out of the box.

140mm Brake Rotors Equipped with premium 140mm rotors that provide consistent, powerful braking performance in all conditions. The 140mm size offers the optimal balance of stopping power and weight savings for performance-focused riders.

Why This Setup Works

This 404/808 combination has been proven in Ironman World Championships and major time trials worldwide.
