Reserve 40|44 GR Wheelset

The Reserve 40|44 GR Wheelset is built for gravel riders chasing maximum speed, stability, and versatility across everything from fast dirt roads to demanding backcountry adventures. Designed with an aerodynamic focus while maintaining the durability and practicality gravel riding demands, the 40|44 GR brings Reserve’s advanced wheel technology to modern drop-bar off-road riding.

At the center of the design is Reserve’s mixed-profile rim configuration, pairing a 40mm front wheel with a deeper 44mm rear wheel. This setup takes advantage of Turbulent Aero technology to improve aerodynamic efficiency while maintaining predictable handling in changing wind conditions. The result is Reserve’s fastest and most stable gravel wheelset to date, equally at home lining up for a gravel race or covering huge miles on remote mixed-surface rides.

The wider internal rim profile is optimized for modern high-volume gravel tires up to 50c, delivering improved tire support, enhanced traction, and greater ride comfort across rough terrain. A semi-hooked rim design simplifies tubeless setup and improves tire security, making it easier to run lower tire pressures for added control and compliance.

Reserve also focused heavily on long-term reliability and ease of service. Internally reinforced spoke holes strengthen the rim at one of its highest stress points without adding unnecessary weight, improving durability for hard riding and rough surfaces. External nipples and standard spokes make maintenance straightforward whether preparing for race day or servicing the wheels after a long season of riding.

Like every Reserve wheelset, the 40|44 GR comes backed by a lifetime warranty and no-fault crash replacement program, along with no rider weight limits and no restrictive tire limitations. Whether ridden tubeless or with traditional tubes, these wheels are designed to perform consistently across the full spectrum of modern gravel riding.

The Reserve 40|44 GR Wheelset is a high-performance aero gravel wheelset engineered for speed, stability, durability, and all-day versatility on modern mixed-surface terrain.
