The GRAVAA R-40|44 is the result of a partnership between top-quality brands GRAVAA, Reserve Wheels and DT Swiss. The wheelset consists of Reserve 40|44 rims and are equipped with GRAVAA’s KAPS technology and DT Swiss’ hub parts. Altogether, this set will make you the fastest rider on every terrain. This wheelset is made for competition road and gravel racing, and the 25.5 | 25 mm inner width aero rims allow the use of various tyre widths.

The lightweight wheels compose of carbon rims and advanced hubs, in which a miniature high-pressure pump is stored. This pump is driven by the rotation of your wheels: by you. Via an integrated clutch unit and electro-pneumatic wireless control system the pump gets only active on demand. The wheels are fully compatible with standard bikes with disc brakes. You manage your tyre pressure wireless from your handlebars. Meanwhile, all relevant information can be displayed on your bike computer or smartphone.
