Description

Bringing cutting-edge performance to the diverse needs of off-road drop-bar riders, 40|44 GR gravel wheels are tailored for the demands of gravel riding with an aero focus. Leveraging Turbulent Aero technology, 40|44 GR wheels feature a 40 mm front rim paired with a 44 mm rear rim, making it an obvious choice for anyone looking for more speed on and off the pavement. 

Wider than our previous gravel wheels to allow for tires up to 50mm, 40|44 GR play nicely with modern high-volume gravel tires, and a semi-hooked bead makes tire selection and 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. In keeping with Reserve's sensible ways, you’ll find external nipples, standard spokes and no rider weight limits.

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.

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.
