To the asphalt, and beyond!
You've got big plans for your riding, searching for miles in unlikely places from overlooked mountain passes to gravel fire lanes and anything in between. The freedom of two wheels is fully realized when your riding is truly free, and that's what Zipp sought to provide with their new 303 Firecrest Tubeless Disc Brake Carbon Clincher Wheelset. Built from the ground up to be tubeless, this wheelset features a redesigned rim optimized for disc brakes.
The new 303 Firecrest rims feature the same drag reducing A.B.L.C. dimples and AeroBalance™ design, keeping the Firecrest line leading the pack in aerodynamic performance and crosswind stability. The new rim design features an internal diameter of 21mm complete with internal ridges, providing a firm anchoring point for tubeless tires as well as a smooth transition between rim and tire. These new rims even feature a new and improved carbon fiber layup that saves even more weight without affecting the 303's legendary durability. Furthering optimizing this wheelset for use with disc brake system, the Zipp 77/177D hubset provides a lightweight and versatile 6-bolt compatible hub that is compatible with either quick release or thru-axle systems. Lacing these lightweight carbon fiber rims to the versatile hubs are 24 front and rear Sapim CX-Ray spokes, ensuring these wheels provide a stiff, responsive riding experience.
The Zipp 303 Firecrest Tubeless Disc Brake Carbon Clincher includes the Zipp Tubeless valve extender and valve-core wrench, Zipp rim tape (factory taped), Zipp Tangete quick-release skewers, Zipp thru-axle end caps. Compatible with Shimano/SRAM 10/11-speed drivetrains.
