Reserve 40|44 GR Carbon Gravel Wheelset
Bringing cutting-edge performance to the diverse needs of drop bar off-roaders, Reserve’s new 40|44 GR gravel wheels are tailored for the demands of off-road exploration and gravel riding, but with an aero focus.
Leveraging Turbulent Aero technology, the 40|44 GR features a 40mm front paired with a 44mm rear, establishing it as our fastest and most stable gravel wheelset to date. Wider than our previous gravel wheels to allow for tires up to 50c, the 40|44 GR plays nicely with today’s slew of big-volume gravel tires, and a semi-hooked rim makes tubeless setup easier than ever.
Like all Reserve wheels, the 40|44 GR wheels have a lifetime warranty supported by a no-fault crash replacement. And in keeping with Reserve workmanlike ways, you’ll find external nipples, standard spokes, no tire limitations and no rider weight limits.

Key Features
Mixed Profile Front and Rear: The 40|44 GR utilizes a 40mm front rim for maximum crosswind stability, paired with a 44mm rear rim optimized for lowest weight and maximum aerodynamics.
No Fuss Design: Designed to be your reliable gravel companion. There are no rider weight limits, no tire brand limitations, and they can be run tubeless or with standard tubes. Built with standard J-bend spokes and external nipples for easy servicing anywhere in the world.
Internal Spoke Reinforcements: Reserve uses internally reinforced spoke holes to strengthen the area where the rim sees the most force (around the spoke nipple). This significantly improves rim durability without adding unnecessary rotational weight.
