The Zipp 303 S Series Tubeless Disc Brake Wheel offers modern road cyclists the versatility they demand when it comes to the speed they strive for. Building on the legacy of the Spring Classics, this 303 wheelset maintains its ideal 45mm rim height for all terrain, but adds significantly greater internal width to deliver more power and ride quality in almost every measurable way.

- New Zipp graphics and visual presence that embodies speed
- Fastest with 28 mm tires, but also fits wide gravel tires
- Wide rims optimize tire shape to allow for lower tire pressure, especially with tubeless tires. The result is a larger contact area for more grip and therefore more safety in curves, downhill runs and when handling on wet roads
- Lower tire pressures and larger volume ensure a more comfortable ride and less vibration

- Wide hookless rims create a seamless transition to the tire and reduce air resistance
