Zipp 808 Firecrest Carbon Clincher Tubeless Disc Brake Front Wheel

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. The 808 Firecrest Tubeless Disc-brake builds on the legacy of the 808 as the perfect choice for flat to rolling road rides, races, time trials and triathlon. Pair an 808 Firecrest Disc-brake rear wheel with a 404 Firecrest Tubeless Disc-brake front… Or rock dual 808s for max aero efficiency. How you slow down plays an important role in how fast you go. Efficient speed adjustments on technical sections of road are crucial to conserving energy and maintaining speed. Disc-brakes gained prominence in mountain biking and then cyclocross and now are being embraced for road riding and racing. It’s no wonder. The consistency and power of disc brakes provides precision modulation and stopping power, literally at your fingertips. 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, our 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 Zipp Tubeless valve – factory installed 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 Firecrest With the new proprietary Firecrest rim shape in our 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality. Carbon Clincher Our superior Carbon Clincher technology is the culmination of two years of intensive prototyping and testing. We worked with our composites supplier to develop an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards. ABLC™ (Aerodynamic Boundary Layer Control) Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
