ZIPP 303 FIRECREST CARBON DISC BRAKE TUBELESS WHEELSET W/ CHRIS KING R45D CERAMIC HUBS
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 while maintaining low weight and the world class speed of Chris King hubs. These wheels take on high speed aero performance while maintaining proper balance at high speeds. 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. The design of the rim allows these wheels to be aerodynamically optimal with 25mm tubeless clincher tires, helping balance ride quality with speed.

This version of the Zipp 303 Firecrest Wheelset is equipped with Chris King R45D Centerlock Hubs. With 30 years of bearing experience and 20 years of hub building behind them, the R45D Hubs are nothing short of world class. The hub utilizes Zipp’s redesigned RingDrive system which features 45 teeth for low drag and lightning fast engagement. These lightweight hubs also include high-level ceramic bearings which have been heat treated and manufactured to promote unmatched speed. Chris King bearings are designed to last and get faster as they age. This hub is ready to give riders unmatched engagement and outstanding power.

On top of their amazing speed, the Zipp 303 Firecrest Chris King wheels are extremely durable and reliable. 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. With black spokes for a sleek look, these wheels are the complete package. The Zipp 303 Firecrest Chris King wheels offer incredible speed, long-lasting reliability, and excellent balance at a reasonable price.
