Speed for all roads ahead.

Zipp's 303 S Firecrest Tubeless Disc-brake wheelset provides today's cyclists the versatility they demand with the speed they crave.

Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever, no matter the road surface, but just as fast as before. The 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike.

This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement.

Lightweight. Aero. Gravel-Ready.

The 303 S is among Zipp's lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide.

The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tire bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tire. The wide rim optimizes tire profile to allow lower tire pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tire, according to internal Zipp testing.

This groundbreaking wheelset also features all-new cosmetics, setting the rider apart from the pack, and comes at an attractive price.

Features:

  • New Zipp graphics and cosmetic identity that scream speed
  • Fastest with 28mm, fits wide gravel tires as well
  • Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increase grip for confident cornering, descending, and handling in wet conditions.
  • Lower tire pressures and larger volume provides a compliant ride with fewer vibrations.
  • Significant watt savings when running larger tires at lower pressure.
  • Wide hookless rims create a seamless transition to the tire, reducing drag
  • 76 / 176 DB hubs with center locking interface
  • XDR driver body option
  • Lock ring included
  • Tubeless Tires Only - These wheels are tubeless specific but can be used with a tube when needed
  • Lifetime Warranty

  • FREE Cassette Installation - Order a cassette along with a wheelset and we can install the cassette for free. Cassette installation requires special tools that not all our customers have.

    Fast and affordable wheels

    I got these wheels with their RT28 tires and it was simple to install. I like the feeling of the bike now that I can run them at lower pressure (in my case 55psi front and 58psi rear). They are super comfortable and have made me at least 1-1.5mph faster.

    Amazing wheels!

    Upgraded from the stock DT Swiss R470db wheels on my Roubaix. Huge difference! Feel like I am flying up inclines.

    Mounted them with 30c Schwalbe Pro One tires. Smoothest ride ever.

    Installed on Trek Emonda SL6

    Installed on my Trek Emonda SL6 and it transformed the bike from something I was going to sell, to my new favorite. These are a game changing wheelset. I am genuinely faster on climbs with these. As a nice bonus, I am also much more confident on descents and higher speed cornering on these as well.
