The fastest off-road wheels Reserve has 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 Reserve's 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 maximise aerodynamic performance, while the 30mm internal width is optimised for modern gravel tyres. Together, greater grip, stability, and confidence. Tying it all together is Reserve's lightweight hollow-hook construction, delivering exceptional strength and pinch-flat protection without the weight penalty - all backed by Reserve's lifetime warranty.
FEATURES
Aero Optimisation
The super-wide 44mm external rim profile allows air to transition smoothly across the tyre and around the rim, reducing drag and increasing speed. This buffer of smooth-flowing air is the key to increasing aerodynamic performance.
Hollow Hook Design
Reserve's hollow-hook design allows a super-wide internal and external rim without drastically increasing the weight of the rim. The design removes excess material inside the rim. Keeps things light while still delivering pinch flat protection and strength. Backed by Reserve's lifetime warranty.
30mm Internal Width
Made for modern gravel race tyres, a 30mm internal width allows the tyre to sit wider on the rim. This creates a wider contact patch for more grip. The design also prevents tyres from 'lightbulbing', where the sidewalls taper in narrower than the widest point of the tyre, reducing the contact patch.
