ZIPP 303 XPLR S Carbon B1 Front Wheel

The Zipp 303 XPLR S Carbon B1 Front Wheel is a fast carbon gravel wheel made for rough roads, racing and fast gravel riding. Its ultra-wide 32mm internal rim width supports larger gravel tyres at lower pressure, which helps reduce vibration, improve grip and add control. A 54mm deep rim profile also helps cut drag, so the wheel can hold speed well on fast gravel routes.

Key Features and Benefits:

Ultra-wide 32mm internal rim width: The wide rim gives approved 40c to 60c tubeless-ready tyres a broad and stable base. This lets the tyre sit with better shape and support, so you can run lower pressure with more grip and less harsh feedback.

Hookless Tubeless Straight Side rim construction: The hookless rim is made for approved tubeless-ready tyres and helps create a clean tyre-to-rim fit. This supports fast set-up with sealant or tubes, giving the wheel a simple and reliable gravel-ready build.

Designed for 40c to 60c TLR tyres: The wheel is built around modern gravel tyre sizes, giving you room to choose more volume for rougher ground or a faster tyre for racing. This helps you match the wheel to your route, pace and terrain.

54mm deep carbon rim profile: The deep rim helps improve aerodynamic performance at gravel speeds. This supports better speed on open tracks and firm roads, so the wheel feels efficient during hard efforts.

Low-pressure support under 30psi: The rim and tyre system is designed to work well at lower pressure. This helps reduce trail buzz and improve contact with the ground, giving more comfort and control over rough sections.

Centre Lock disc brake fitment: The front wheel uses a Centre Lock disc brake interface for a secure and clean rotor fit. This makes rotor installation simple and supports consistent braking performance in mixed conditions.

24-hole 2-cross spoke build with CX Sprint spokes: The 24-spoke layout and 2-cross pattern help balance strength, stiffness and ride feel. CX Sprint spokes add support under load, giving the wheel a strong build for fast gravel use.

12x100mm thru axle fitment with 12mm end caps: The wheel ships ready for modern 12x100mm front thru axle gravel bikes. This gives a secure front-end fit, helping the bike track well under braking and through rough terrain.

The 303 XPLR S front wheel is built to help gravel riders go faster without giving up control. The wide rim and low-pressure support help smooth rough tracks, while the deep carbon profile keeps the wheel efficient on faster ground. It is a strong choice for riders who want one front wheel for racing, training and demanding gravel routes.

For a fast, stable and durable front wheel built around modern gravel tyres, the ZIPP 303 XPLR S Carbon B1 Front Wheel is a practical upgrade for serious mixed-surface riding.
