Compatible tires
The Zipp 303 Firecrest wheelset is aerodynamically optimized for 28mm wide tubeless tires. For more comfort and grip, however, it also copes with wider tires up to 55mm. The wide rims are optimized for lower tire pressures, especially with tubeless tires. The maximum tire pressure is only 5 bar. As a result, however, this leads to a larger contact area, higher comfort, more grip and lower rolling resistance.
The hookless rims of the 303 Firecrest are only suitable for tubeless tires. Folding tires are therefore not compatible with the Zipp 303 Firecrest! The tires can be mounted tubeless or with a conventional tube. An overview of the compatible tires can be found here.
Aerodynamics
The rim is a full 30mm wide and the rim bed measures 25mm. The Zipp 303 Firecrest is aerodynamically optimized for 28mm tires. Due to its width, the rim optimizes the tire shape and thus allows a lower air pressure. This not only reduces rolling resistance but also makes riding more comfortable.
Weight
The Zipp 303 Firecrest Tubeless Disc Brake wheels have a low weight of only 1352 grams, despite the 40 mm high aerodynamic rims.
Tire mounting
The rims are optimized for easy, tool-free mounting of tubeless tires. No more need for a compressor to mount tires. Yeah!
Compatible cassettes
The Zipp 303 Firecrest are available with 2 different freewheel bodies:
Shimano/SRAM 10/11/12-speed: The classic Shimano HG freewheel. All 10, 11 and 12-speed Shimano Road and SRAM Race 10 and 11-speed cassettes can be mounted.
SRAM XDR 12-speed: The XDR freewheel body is only compatible with SRAM XDR 12-speed cassettes.
Rims
The Zipp 303 Firecrest Tubeless rim is a full 30mm wide and the rim bed measures 25mm. It is made of carbon. Conventional folding tires require a hook rim to sit securely on the rim. The 303 Firecrest lacks this hook. The tubeless tire design ensures that the tire sits on the rim through the tire pressure. This allows wider tires to be mounted with less air pressure. The rims feature Zipp's characteristic dimple structure. The ensures that the air flows better and with less friction over the rim surface. Overall, this leads to better aerodynamics, lower rolling resistance and higher comfort with the Zipp 303 Firecrest!
Spokes
Zipp makes no compromises and uses the tried and tested Sapim CX-Ray spokes with the 303 Firecrest.

Zipp uses the Zipp ZR1 hubs with the 303 Firecrest wheels. The hub were designed in Germany. They are equipped with sealed and maintenance-free industrial bearings with very low friction.
