ZIPP 404 Firecrest Disc Carbon Centerlock rear wheel

The Zipp 404 Firecrest Carbon Tubeless rear wheel for disc brakes is a lightweight and aerodynamic all-round wheel with 58mm rim height. It is optimal for riders who like to climb and also ride on the flats. The 404 Firecrest rear wheel is suitable for road, gravel and even cyclocross.

With only 790g the 404 Firecrest rear wheel is real lightweight. The wide rims are optimized for 28mm tires. This combination combines low rolling resistance, sophisticated aerodynamics, comfort and safety. The 404 Firecrest rim also goes along with wider tires up to 50mm. The installation is very easy with Zipp's "Tubeless Made Easy" system and works even without a compressor. The Zipp ZR1 hubs are state of the art and respond through a 6-pawl body with 66 detent points even faster.

Compatible tires

The Zipp 404 Firecrest rear wheel is aerodynamically optimized for 28mm wide tubeless tires. For more comfort and grip, however, it also copes with wider tires up to 50mm. 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 404 Firecrest are only suitable for tubeless tires. Folding tires are therefore not compatible with the Zipp 404 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 23mm. The Zipp 404 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. 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 404 Firecrest!

Weight

The Zipp 404 Firecrest Tubeless Disc Brake rear wheel has a low weight of only 790g, despite the 58 mm high aerodynamic rim.

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 404 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 404 Firecrest Tubeless rim is made of carbon. Conventional folding tires require a hook rim to sit securely on the rim. The 404 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 404 Firecrest!

Spokes

Zipp makes no compromises and uses the tried and tested Sapim CX-Ray spokes with the 404 Firecrest.

Hubs

Zipp uses the Zipp ZR1 hubs with the 404 Firecrest wheels. The hubs were designed in Germany. They are equipped with sealed and maintenance-free industrial bearings with very low friction.
