Reserve 48|53 GR Wheelset

The Reserve 48|53 GR Wheelset represents the fastest off-road wheels Reserve has ever built, engineered for gravel racers who refuse to leave any advantage on the table. Combining Turbulent Aero technology with an innovative wide hollow-hook rim construction, the 48|53 GR delivers maximum speed, predictable handling, and exceptional flat protection across the most demanding gravel race courses.

Every dimension of the 48|53 GR has been designed with speed in mind. The asymmetric rim profile, 48mm front and 53mm rear, is the foundation of Reserve's Turbulent Aero design philosophy. The shorter front rim prevents unpredictable handling in aggressive crosswinds, while the taller rear rim improves aerodynamics without influencing the bike's steering characteristics. This system-optimized approach delivers all-day speed across flat-out courses while maintaining the predictable, smooth handling that gravel racers depend on when conditions get difficult.

The super-wide 44mm external rim profile is the key to the 48|53 GR's aerodynamic performance, allowing air to transition smoothly across the tire and around the rim to reduce drag and increase speed. Paired with a 30mm internal width optimized for modern 40-57mm gravel race tires, the design creates a wider contact patch for superior grip and stability while preventing tires from lightbulbing, where sidewalls taper narrower than the tire's widest point and reduce traction.

Reserve's innovative hollow-hook construction removes excess material from the outermost section of the rim, delivering exceptional strength and pinch-flat protection without the weight penalty typically associated with wide-profile gravel wheels. This engineering breakthrough keeps the wheelset light and race-ready while providing the durability and reliability that long-distance gravel racing demands.

Whether charging across high-speed gravel roads, navigating technical mixed-surface terrain, or sprinting for the finish line, the 48|53 GR delivers the confidence, speed, and protection that competitive gravel athletes need to perform at their best.

Includes complete wheelset, XDR or HG-EV driver, Reserve rim tape (installed), 70mm and 90mm Fillmore tubeless valves, and white Reserve rim decals.
