There’s nothing middle of the road about the 808 Firecrest. At 82mm deep, it’s all out aero. Thanks to refinements to Zipp’s revolutionary Firecrest rim shape to be tubeless compatible and optimized for wider tires, the 808 Firecrest Carbon Clincher Tubeless Disc brake is ideal for the new era of disc brake road riding and racing.
Without the constraints of rim brake caliper compatibility or brake-track requirements, the Firecrest Carbon Clincher Tubeless Disc-brake wheels offer the increased stopping power and modulation of disc brakes and a whole lot more.
To maximize the aero performance of the wheels, Zipp’s ABLC dimples extend all the way to the outer edge of the disc-specific rims. The wheels are also optimized for wider tires to meet the performance needs of modern riders in search of low rolling resistance and aero efficiency with high comfort. The deeper Firecrest Tubeless Disc brake has an internal width of 19mm and are aerodynamically optimized for 25mm wide tires. This design improves Firecrest’s ability to yield low aerodynamic drag and high crosswind stability, a combination called AeroBalance.
Designed to be tubeless compatible, the wheels feature a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance even when ridden at lower tire pressures. Zipp’s low rolling resistance and high grip Tangente RT28 and RT25 Road Tubeless tires pair well with the Firecrest disc brake wheels.
A new carbon fiber layup for the Indianapolis-made rims keeps weight low while maintaining the Firecrest Carbon Clincher’s proven durability. The robust 77D/177D hubset, paired with 24 Sapim CX-Sprint spokes front and rear, keeps the wheels stiff and responsive. To ensure compatibility with any bike, the versatile 77D/177D hubs come with swappable end caps to work with QR’s and thru-axles, including 12x100mm and 15x100mm front thru-axles as well as 12x142mm rear thru-axles. The 177D rear hub is also XDR driver body compatible for use with SRAM 10-42 cassettes.
Each Wheel Includes:
- Zipp Tangente Quick Release Skewer

- Tubeless rim tape – factory installed
- Valve core removal tool
- Zipp 77D/177D thru-axle caps to fit 12x100, 15x100 dropouts for front wheels, and 12x142 dropouts for rear wheels
- Freehub body spacer – 11 to 10 speed
- SRAM XDR driver body for 177D available separately
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
