Zipp 303 Firecrest Carbon Disc Brake 650b Tubeless Wheelset

ZIPP 303 FIRECREST CARBON DISC-BRAKE 650B TUBELESS WHEELSET
The Zipp 303 Firecrest wheels are a part of Zipp’s mission to create a balance of great aerodynamics and stability. This Firecrest version comes in at a lower price than NSW without adding a significant amount of weight. Zipp calls this combination of attributes “AeroBalance.” Without proper control, there is really no use to aerodynamics on a road bike, so the 303 Firecrest wheels focus on both for confident speed. These wheels can accomodate larger tires to properly balance stability with speed. The Firecrest version of these wheels utilizes a ZR1 hub which provides low rolling resistance and excellent durability while lowering the overall price.

As the definition of road riding expands, some riders need a more diverse wheel to accommodate dirt and gravel excursions. These 650b wheels are perfect for taking on those challenges and double as a proper fitting wheel for smaller riders. They have a lightweight carbon layup but can still withstand the punishment of long training days, Gran Fondos, and even cobblestone roads. To help with other tough conditions such as rain or poor roads, these wheels are disc brake compatible for confident and modulated stopping. Running tubeless tires will also lead to more durability with top-notch flat protection. The Zipp 303 Firecrest wheels are for the rider who want both low weight and aerodynamics for each day on the road.
