The Zipp 202 Firecrest Carbon Clincher Tubeless Disc-brake wheelset is harnessing high technology and for high adventure. Without the constraints of rim brake caliper compatibility or brake-track requirements, the 202 Firecrest Tubeless Disc-brake wheelset open new adventures, paved or not. What’s more, we’ve revised our industry changing Firecrest rim shape to be tubeless compatible, disc-brake specific, and more effecient at creating a fast and stable ride in any wind condition.
Considering Road Tubeless?
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 also are 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 designs at each rim depth. The new 202 Firecrest Tubeless Disc-brake wheels has an internal width of 21mm and are aerodynamically optimized for use with 28mm wide tires. The new designs improve Firecrest’s ability to yield low aerodynamic drag and high crosswind stability, a combination we call AeroBalance™.
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 pairs perfectly with this wheel. The RT25 Road Tubeless tire is another excellent option.
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.
