Zipp’s original 303 Tubular made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest® platform, and now the revolution continues with the inclusion of the 77/177 hubset – best-in-class durability and improved bearing protection with no pre-load adjustment needed.

  • Optimized flange geometry and spoke hole attachment pattern with Sapim® CX Sprint spokes to optimize torsional and lateral stiffness and robustness.
  • Includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, lever contours neatly with the frame.
  • New robust hub platform with distinctive graphics.
  • For those looking for a wider gear range, or tackling especially extreme terrain, a XD driver body for 177 is sold separately and easily installed to allow for more cassette options including a 10-42. The hubset is designed to swap driver bodies without re-dishing wheel.

Zipp’s Carbon Clincher technology preserves the aerodynamic advantages of the 303 Firecrest’s tubular brother, while adding the convenience of a clincher tire. And at just 1,645g, it’s light enough to climb up the steepest gradients with ease as a go-to all-around wheelset.

Different colours of rim stickers available.
