Zipp 303 XPLR S – for fast and efficient gravel riding

Zipp 303 XPLR S Tubeless Disc Brake – a carbon rear wheel designed for fast gravel riding. The extra-wide rim profile is designed for wider gravel tires and allows lower tire pressures, helping to reduce vibrations from rough surfaces while maintaining good traction.

The 303 XPLR S is designed around Zipp's Total System Efficiency (TSE) concept, adapted for gravel riding conditions. The 32 mm internal width and 54 mm deep rim profile creates a smoother transition between the rim and a wide gravel tire for improved aerodynamic efficiency.

The wheel uses a Hookless / Tubeless Straight Side (TSS) construction and is compatible only with Zipp-approved 40–61c TLR tires. They can be used with sealant or an inner tube. The maximum permitted tire pressure is 3.45 bar / 50 psi.

The rear wheel version uses a 176D hub, while the brake rotor uses the Center Lock mounting standard. The wheel is designed for a 12x142 mm rear axle.
