Zipp 303 S Tubeless Disc Brake Road Bike Wheels

With the Zipp 303 S Tubeless Disc Brake road bike wheels, Zipp has put a wheel set on the market for every cyclist who is looking for speed. The Zipp 303S is the successor of the Zipp 302 and is inspired by the popular all-round Zipp 303 wheels, but is just a bit more attractively priced. The Zipp 303 S Tubeless Disc Brake wheels have a low weight of only 1540 grams, despite the 45 mm deep aerodynamic rims. This makes them suitable for both the flat and the mountains.

The wide rim with an internal rim width of 23 mm allows the fitting of tyres from 25 mm to 50 mm. You won't find a more all-round wheelset; the 303S is suitable for road racing, gravel riding and even cyclocross. With an internal rim width of 23 mm, external rim width of 27 mm and a depth of 45 mm, the 303S saves 10 watts at a speed of 40 km/h compared to the "old" Zipp 302 Disc, according to internal wind tunnel tests.

The Zipp 303 S Tubeless Disc Brake wheels are built around Zipp 76/176 Disc Brake hubs and spoked with aerodynamic Sapim CX-Sprint spokes. The new wide carbon rims are tubeless ready, which means that you can ride with or without an inner tube. Tubeless riding with lower tyre pressure means lower rolling resistance, increased comfort and better grip.

Tubeless ready
Making your wheels tubeless has never been easier. The rims have been optimised for easy fitting without tools and no compressor is needed to fit the tyre. The wide hookless rims are also designed for lower tyre pressures, specifically in combination with a tubeless setup. Hence the maximum tyre pressure is "only" 5 Bar (72.2 PSI). The result is a larger contact area with the ground for more grip and manoeuvrability, on descents and when riding in wet conditions.

Zipp 76/176 hubs
These wheels are built from the trusted Zipp 76/176 hubs and feature low-maintenance, durable and well-sealed industrial bearings. The Zipp 76/176 hubs use a 3-pawl system.

Hookless rims
Zipp 303 S Tubeless Disc Brake rims are designed without hooks to hold the edge of the tyre. The pressure of your inner tube combined with the edge of the special 'hookless-compatible' outer tubes ensure that the tyre stays in place. This allows you to mount wider tyres, and you will experience less resistance. In short: more comfort and higher speed!

Zipp Lifetime Warranty
The Zipp Lifetime Warranty gives you a lifetime warranty against manufacturing defects. This gives you ultimate security! The warranty becomes effective after registration of your wheel(s) with Zipp and is non-transferable.

Please note:
If you want to ride with inner tubes, you can only do so when you use tubeless-ready tyres. These sit tighter around the rims than regular folding tyres.
