Zipp 303 Firecrest Tubeless Rear Disc Brake Wheel CL

Zipp’s 303 Firecrest Tubeless disc-brake rear wheel is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple.

Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp’s drive to conquer the spring classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: wind resistance, rolling resistance, rider fatigue, weight.

This hubset features 66 points of engagement for quicker response. The 303 Firecrest tubeless disc-brake wheelset is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.
