WITHOUT LIMITS. Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever.
- At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp® 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With an all-new disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features 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. A new carbon fibre layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while our robust 77/177D hub set, keep the wheels stiff and responsive.
