Zipp 303 S CarbonHookless Tubeless Disc Brake Center Lock Rear Standard Graphic Sram Shimano 24H (rear only)

The newly launched Zipp 303 S is effectively a complete update to the existing 302 carbon wheel, a model that itself broke new boundaries for the brand via its lower price point. Like the 302, the new 303 S is aimed more at the endurance and gravel end of the spectrum rather than racing – although there’s nothing stopping you using these for that either.

This new 303 S however, goes one huge leap further and is the first carbon Zipp wheel to break the magic price point. But don’t call it a ‘budget’ wheel, this isn’t just an outdated, older design that Zipp has rehashed to open up the market. No, the 303 S has a completely new and up-to-date rim design that promises a lot for the rider.

 KEY FEATURES:

• XDR driver body option
• 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.

In fact, comparing the new 303 S to the 302 is actually quite difficult, with Zipp preferring to refer to this new wheel as part of the 303 wheel family. Yes, both wheels share the same 76/176 hubs, a hub set we really rated for ease of maintenance and simple standardised construction and the rear wheel sticks to 24 spokes laced in a two-cross pattern. Everything else is different, especially the rim.
