There’s nothing middle of the road about the 808 Firecrest. At 82mm deep, it’s all out aero. Simply put, this is our fastest Firerest disc-brake wheelset. 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 new 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. In developing these wheelsets, Zipp engineers examined three different external rim shape concepts, and within each of those shapes, four separate internal widths before selecting the most efficient design. The deeper Firecrest Tubeless Disc brake has an internal width of 19mm and are aerodynamically optimized for 25mm wide tires. The new designs improve Firecrest’s ability to yield low aerodynamic drag and high crosswind stability, a combination we call 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 new Firecrest disc brake wheels.
