Zipp 303 XPLR S Carbon Gravel Wheelset - 700c, Hookless, Center Lock, XDR, 12x100 / 12x142, 54mm Deep
The Zipp 303 XPLR S is the practical performance version of Zipp’s dedicated gravel aero platform—built for riders who want real speed gains without stepping all the way into 303 XPLR SW pricing.
This is important: this is the 303 XPLR S, not the higher-end 303 XPLR SW. You still get the wide 32mm internal hookless rim, deep 54mm aero profile, and gravel-specific Total System Efficiency design—but with a more affordable hub system and build package that makes more sense for many real-world riders.
This listing is built as a complete wheelset using separate front and rear wheels. Rear wheel uses an SRAM XDR driver, which is critical for drivetrain compatibility.

Compatibility & Technical Notes
Good Fit: SRAM XDR gravel drivetrains including XPLR, AXS, Force, Rival, and high-performance gravel race builds using approved wide tubeless gravel tires.
Not A Fit: Shimano HG, Shimano MicroSpline, or standard XD users without correct driver conversion. Not for traditional hooked clincher tire use. Must use approved tubeless-compatible hookless tire setups.
This is one of the biggest buying mistakes on these wheels—customers assuming all gravel tires are compatible with hookless rims. They are not. Tire selection matters.
Service / Ownership Context
The 303 XPLR S is often the smarter buy versus the SW for riders who care more about ride quality and real-world durability than marginal top-end hub upgrades. You get the same major ride-defining rim architecture that makes the XPLR platform special.
For riders building a serious gravel race bike without overspending, this is often the better value decision.
