The Reserve 40/44 GR is a premier carbon wheelset engineered specifically for the evolving demands of high-speed gravel racing and rugged off-road exploration. Developed using proprietary Turbulent Aero technology, this wheelset features a mixed-profile design—a shallower 40mm front rim for exceptional stability in crosswinds and a deeper 44mm rear rim for maximum aerodynamic efficiency. This configuration makes it the fastest gravel-specific wheelset in the Reserve lineup, perfectly suited for riders who refuse to compromise on speed when the pavement ends.

Beyond its aerodynamic prowess, the 40/44 GR is built for modern high-volume tyres, featuring a generous 27mm internal width that supports rubber up to 50c. The semi-hooked rim bed ensures a hassle-free tubeless setup while maintaining compatibility with standard inner tubes. Designed to be a "no-fuss" racing partner, these wheels feature internally reinforced spoke holes to provide superior strength where the rim faces the most force, ensuring long-term durability without adding unnecessary weight.
