Overview

Why Is the Zipp 303 XPLR S Built for Gravel Racing?

The Zipp 303 XPLR S is the accessible entry point into Zipp's gravel-specific wheel technology, borrowing key innovations from the premium XPLR SW and delivering them at a price that opens the category to more riders. The defining feature is the mega-wide hookless rim, engineered specifically for the geometry of approved gravel racing tires to create a seamless tire-to-rim integration that improves aerodynamic efficiency on gravel surfaces. By increasing air volume through the wider profile, the 303 XPLR S allows lower tire pressures without squirm, absorbing surface vibrations and maintaining grip on technical climbs and loose corners.

Built light to keep you fast and fresh across long gravel days, the 303 XPLR S pairs performance with robustness for the demands of off-pavement riding. Compatible only with Zipp-approved gravel tires, it is critical to reference the Zipp tire compatibility chart before mounting. Available as front 12x100mm or rear 12x142mm SRAM XDR, sold individually. For gravel riders who want Zipp's Total System Efficiency approach to tire-wheel integration without the SW price tag, the 303 XPLR S is the right starting point.

Why does the 303 XPLR S require approved tires?

Zipp lists the 303 XPLR S as compatible only with approved tires, and names the Goodyear XPLR Slick and Goodyear XPLR Inter as designed and optimized for it. Its mega-wide rim is shaped to integrate with approved gravel racing tires. Check the Zipp tire compatibility chart before mounting.

How does the 303 XPLR S differ from the 303 XPLR SW?

Both use a 54mm deep rim with a 32mm internal width for approved gravel tires. The 303 XPLR S uses Zipp 76/176 hubs, and the 303 XPLR SW uses the ZR1 Disc Brake hub with 66 points of engagement. Zipp says the S borrows key innovations from its premium wide gravel wheelset at a lower price.

Can I use the 303 XPLR S for road riding?

Zipp built the 303 XPLR S for gravel, and it works only with approved tires. Check the Zipp tire compatibility chart before you mount any tire.
