Aerodynamic carbon wheels for a modern tubeless disc-brake bike? Yes please.

The Zipp 303 Firecrest Tubeless Carbon Clincher wheelset takes their industry leading 45mm deep 303 Firecrest rim and redesigns it specifically for a tubeless setup on disc-brake equipped road bikes. The new 303 still delivers the same industry leading crosswind stability and low aerodynamic drag that Zipp is famous for, while adhering to modern expectations of how hard and how far bicycles are able to be ridden, on and off road.

Adaptable and capable.

Featuring Zipp's 77/177D hubset, The 303 Firecrest's are extremely versatile, and include swappable end caps that work with quick-release or thru-axles.

The wheels utilize a rim bed made with internal ridges to lock tire's in place, even when ridden tubeless at low pressures. The 303 Firecrest's were designed to accept and facilitate wide tubeless tires with an internal diameter of 21mm. The rims also feature a new carbon fiber layup to further reduce weight without sacrificing durability, allowing these wheels to fly up the steepest climbs with ease, even when the road gets rough.


  • Just as at-home on an all-road right as they are on a super-aerodynamic triathlon bicycle
  • VCLC™ vibration-reducing technology sandwiched between layers of carbon in the rim, delivering a 10% reduction in vibration
  • ABLC™ dimples smooth airflow across the rim's surface
  • Twenty four Sapim CX-Ray spokes front and rear keep the wheels feeling stiff and responsive
  • Wheelset includes Zipp tubeless valve extenders and a valve-core wrench, Zipp rim tape, QR skewers and thru-axle endcaps
  • Handmade in Indianapolis, USA
