Aero gravel performance

The GRAVAA x Reserve 40|44 GR wheelset brings cutting-edge aero performance to gravel riding and off-road racing. Tailored for the demands of drop-bar adventurers, the 40mm front and 44mm rear rim profile ensure both stability and speed. Combined with GRAVAA’s revolutionary Kinetic Air Pressure System (KAPS), you can effortlessly adjust tire pressure on the go, adapting perfectly to the changing terrain.

With Turbulent Aero technology for reduced drag, these wheels offer unmatched control and efficiency. The wide rim allows for tires up to 50c, making them compatible with the latest gravel tire trends. Plus, with tubeless-ready setup and GRAVAA’s game-changing tire pressure control, you’ll ride faster, smoother, and with greater confidence on any surface. Backed by Reserve’s lifetime warranty and no-fault crash replacement, this wheelset is built for the long haul.
