Speed For The Road Ahead — All Of Them

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
  • Replacement 76 /176 hub end caps sold separately.

  • 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. The cassette will be professionally installed and torqued to spec. Just add "Please install cassette" to your order notes at checkout and we'll take care of you.

    These are fantastic wheels!
    by Tim

    I've wanted Zipp wheels my entire cycling life and now I finally own a set. They ride very nice and have a low rotational weight. Most people buy these for the aero benefit but I'm old and slow so I don't really notice a huge difference. I am riding 32mm Schwalbe Pro 1 tire which set up tubeless with ease. I've done tons of tubeless set ups for road, mountain and cyclocross. Without a doubt this was the easiest tubeless set up that I've ever done. There are YouTube videos showing guys setting these up with a standard floor pump but in my experience a compressor is the only way to go. Remove the valve core and use your compressor along with the appropriate fitting. If you do it this way you'll find the tire bangs right into place. At least the Schwalbes did. I also had no difficulty getting the tire on the rim. Another bonus is that good rim tape comes factory installed and the valve stem is of good quality. I really love these wheels. They look cool and ride great!

    Running these on both bikes. Gravel rig with 40mm and road bike with 29mm. The matte finish and minimal graphics are choice.

    Fantastic wheelset, worth the wait

    This is my first pair of carbon wheels so I don't have much to compare them to other than my old Mavic Alloy wheelset that they replaced. My average pace has increase 2-3 mph on rides, which is probably more due to the aero rather than weight savings. Comfort has improved significantly since I'm running my tires 10 psi lower. Overall, these were definitely worth the price, especially with the lifetime warranty.

    One thing to be aware of is that I had a lot of problems getting the tire bead to seat on the rim. I put Pirelli P-Zero TLRs on them, which where super-easy to get onto the rim without tire levers. However, I needed to resort to compressed air to blast the bead into place. This was not an issue at all with my hooked Mavic rims.

    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.

    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.

    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.
