Catering for the demands of modern riders, Zipp's 303 S Carbon Tubeless Disc Brake Wheelset is both versatile and fast. It uses a 45mm deep carbon rim with an internal width that's optimised aerodynamically when paired with a 28mm tubeless tyre, however, you can also fit tyres up to 50mm wide, making it a great choice for gravel racing and adventure riding. Developed specifically for disc brake setups and to be run tubeless, you'll benefit from the comfort, fast-rolling and puncture protection that running lower air pressure brings. Zipp's own 76D and 176D hubs are laced to the rim using 24 Sapim CX-Sprint spokes front and rear, and the construction is stiff and strong, able to deal with the smoothest tarmac, cobbles and loose gravel alike. The great value of this wheelset makes top performance attributes accessible to more riders.
