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 set up 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 and no rider weight limits.

FEATURES:

• Mixed Profile Front and Rear: The mixed profile front and rear setup of the 40|44 GR provides for maximum stability, lowest weight and optimized aerodynamics.
• No Fuss Design: The 40|44 GR is designed to be your no fuss aero gravel riding and racing wheelset. There are no weight limits, no tire limitations, and can be set up tubeless or with tubes.
• 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 provides for improved strength without adding unnecessary weight.
