Designed for the specific demands of gravel riding, racing, and exploration, Shimano’s new GRX carbon tubeless gravel wheels bring lightweight, reliable performance in a modern gravel wheel package. Whether your preferred riding terrain is fast gravel roads, smooth, serpentine singletrack, or bushwhacking along old goat paths, these lively tubeless-ready wheels deliver the key performance features necessary to assure a great day on the bike.
Shimano’s lightweight GRX carbon wheelset weighs in at just 1,461 grams and features a shallow 32-millimeter rim height for faster acceleration and climbing whether on steady mountain climbs or the endlessly rolling terrain. The shallower rim depth also ensures better control in heavy cross winds, a scenario so common on long rides.
Featuring Shimano’s ultra-reliable cup-and-cone ball bearing hubs, the GRX carbon gravel wheels deliver quick engagement and a lively feel on all riding surfaces. Whether you’re fighting to stay on a wheel during a hectic gravel race start or challenging your riding pals to a town line sprint, the RX870 wheels immediately jump into action.
The GRX carbon rim width is a fully modern 30-millimeter external and 25-millimeter internal, making these wheels suitable for tires from 32-millimeters wide all the way up to 50-millimeters. And the stealth black full-carbon rims are laced with 24 spokes front and rear to maximize strength and reliability no matter how far down the road less traveled your adventures take you.
