Reserve 48|53 GR wheels are built for gravel racers seeking every advantage, combining Turbulent Aero technology with a wide, lightweight hollow-hook rim for maximum speed, control, and flat protection. These are the fastest off-road wheels from Reserve, designed to deliver all-day speed across flat-out courses while providing predictable, smooth handling.
The 48|53 GR features a Turbulent Aero design. The shorter front rim prevents unpredictable handling in aggressive crosswinds, while the taller rear rim improves aerodynamics without affecting the bike's steering. Every dimension is designed with speed in mind, with a 44mm external width that smooths airflow to maximise aerodynamic performance.
Aero Optimization:
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:
The hollow-hook design allows for a super-wide internal and external rim without drastically increasing the weight. The design removes excess material inside the rim, keeping things light while still delivering pinch-flat protection and strength.
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 and prevents tyres from ‘lightbulbing’, where the sidewalls taper in narrower than the widest point of the tyre.
Key Features & Benefits:
- Aero Optimization: The 44mm external rim profile reduces drag and increases speed by smoothing airflow across the tyre and rim.
- Hollow Hook Construction: Delivers exceptional strength and pinch-flat protection while maintaining a lightweight profile by removing excess material.
- 30mm Internal Width: Optimised for modern gravel tyres to create a wider contact patch for improved grip and stability.
