Gmr 22 Carbon Tubeless Disc-brake Gravel Wheelset - 650b

The shallow 22mm height of our new Carbon Gravel wheelset was conceived during  a gusty, coastal gravel race when our designer decided that the 50mm rims he was using weren't the right choice for the occasion.

The rest of the specs were also developed to suit the way gravel bikes are being ridden - wide hookless TLR Carbon rims and a star ratchet hub for optimal responsiveness. 

GMR 22mm rim depth makes for a great all rounder. If you’re looking for a wheelset for every day use, particularly if your riding conditions are often windy, this is the one. The 22mm height offers a great aero boost over a standard alloy wheelset but doesn’t add so much side area that the wind can push you around.

Of course, the shallower rim is also lighter, so it’s well suited to hilly terrain.

The GMR 22 Tubeless Disc-Brake is optimized for wide tires with lower tire pressure to meet the performance needs of modern riders in search of low rolling resistance and high compliance. With an internal width of 30mm, the wheelset is well suited for rough roads.
