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.
All Reserve wheels are built around a simple principle: we have your back. That means no rider weight limits, an industry-leading Lifetime Warranty, safe semi-hooked rim designs and comprehensive customer service.
We are riders like you and we know that breaking a wheel or damaging a Fillmore Valve can be a frustrating experience, especially when it’s keeping you from getting out on your bike. Our promise to you is that we will do our best to get you back riding as quickly as possible. It’s the reason we have made ourselves available through email, chat or by scheduling a video call. We want to be here when you need us most.
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.
