Zipp 303 XPLR SW

Unmatched Speed on Every Surface.

The Zipp 303 XPLR SW isn't just a gravel wheel; it’s a total reimagining of how a wheel and tire should interact in the dirt. Featuring a massive 32mm internal width, this wheel is purpose-built to integrate seamlessly with modern gravel tires, creating an aerodynamic profile that was previously impossible. By allowing for ultra-low tire pressures (under 30psi), the 303 XPLR SW reduces rolling resistance and vibrations, keeping you faster and fresher over the most grueling courses.

Why the 303 XPLR SW is the New Gravel Standard:

• Aerodynamic Integration: The ultra-wide and deep rim profile is designed to "wrap" around gravel tires, effectively making the tire part of the aero-foil. This results in the fastest race wheel ever tested in gravel conditions.

• Ultra-Wide 32mm Internal Profile: This massive width provides superior sidewall support, allowing you to run lower pressures without the tire squirming. Lower pressure means more grip and less energy lost to vertical vibration.

• Tubeless & Hookless Technology: Optimized for modern tubeless setups, the hookless rim transition ensures a smoother tire-to-rim interface for maximum aero efficiency and simplified tire installation.

• ZR1 DB Hubset: Equipped with the high-performance ZR1 hubs featuring 66 points of engagement for nearly instantaneous power transfer the moment you pedal.

• Lifetime Warranty: Ride with total confidence knowing your investment is protected by Zipp's industry-leading lifetime warranty against manufacturing defects.

Technical Specs:

• Rim Internal Width: 32mm

• Hub Model: ZR1 Disc (Center Lock)

• Axle Type: 12mm Thru-Axle (100mm Front / 142mm Rear)

• Spoke Count: 24

• Compatibility: Tubeless & Hookless approved tires only (Max 50psi)

• Weight: ~1,496g (Wheelset)

The Alegro Perspective: The 303 XPLR SW is a "disruptor" wheel. If you are building a gravel racing rig for events like Unbound or The Rift, there is quite literally nothing else like this. The 32mm internal width makes a 40c tire look and perform like a high-speed aero weapon.

The future of gravel speed is wide. Experience the Zipp 303 XPLR SW.
