2026 Reserve Wheels 48|53 GR Wheelset

Built for gravel racers chasing every advantage, the 48|53 GR combines Turbulent Aero technology with a wide lightweight hollow-hook rim for maximum speed, control, and flat protection.

The fastest off-road wheels we’ve ever made. More grip, more speed, more protection against flats.

Made to deliver all-day speed across flat-out courses while providing predictable, smooth handling, 48|53 GR features our Turbulent Aero design. The shorter front rim prevents unpredictable handling in aggressive crosswinds, and the taller rear rim improves aerodynamics without affecting the bike's steering.

Every dimension of 48|53 GR is designed with speed in mind. The 44mm external width smooths airflow to maximize aerodynamic performance, while the 30mm internal width is optimized for modern gravel tires. Together, greater grip, stability, and confidence. Tying it all together is our lightweight hollow-hook construction, delivering exceptional strength and pinch-flat protection without the weight penalty - all backed by our lifetime warranty.

Aero Optimization

The super-wide 44mm external rim profile allows air to transition smoothly across the tire and around the rim, reducing drag and increasing speed. This buffer of smooth-flowing air is the key to increasing your aerodynamic performance.

Hollow Hook Design

Our hollow-hook design allows us to have a super-wide internal and external rim without drastically increasing the weight of the rim. The design removes excess material inside the rim. Keep things light while still delivering pinch flat protection and strength. Backed by our lifetime warranty.

30mm Internal Width

Made for modern gravel race tires, a 30mm internal width allows the tire to sit wider on the rim. This creates a wider contact patch for more grip. The design also prevents tires from 'lightbulbing', where the sidewalls taper in narrower than the widest point of the tire, reducing the contact patch.
