Zipp 808 Firecrest Disc B1

The 808 Firecrest features a hookless rim profile, which is specifically designed for tubeless setups. While you can use a tubeless-ready tire with an inner tube, you must ensure the tire is approved for hookless rims and that you do not exceed the maximum tire pressure of 73 psi.

Despite the deep 80mm profile, the wheel uses Zipp's ABLC Sawtooth dimple technology to manage airflow across the rim surface. This design helps smooth out the transition of air, providing significantly better stability in gusty conditions than traditional deep-section wheels.

This wheel is optimized for wider tires, featuring a 23mm internal rim width. We recommend using tires with a minimum width of 25mm to ensure a safe and proper fit with the hookless rim interface.

The ZR1 hub is designed for durability with enhanced sealing to protect the internals from debris and moisture. It features 66 points of engagement for quick power transfer, and the system is straightforward to service when routine maintenance is required.

While the 808 Firecrest is engineered primarily for aerodynamics on flat to rolling terrain, this generation has seen a significant weight reduction compared to previous versions. It is capable on climbs, but it is most effective when you need to maintain high speeds on flats and descents.

No, the wheel does not include a thru-axle. It is built with 100mm hub spacing for a standard 12mm thru-axle, which is compatible with most modern disc-brake road and gravel frames.
