Built for all-terrain riding and racing, the Shimano GRX WH-RX870 Carbon Gravel Tubeless Wheelset offers quick acceleration on flat paths, steady climbs, and rolling hills alike. The lightweight carbon rim construction weighs in at just 1,461g for the pair, which is why we see this wheelset as a must-have for high-performance gravel riding. With a 25mm internal and 30mm external rim width, our wheels are suitable for tubeless-ready tires between 32 and 50mm, and when combined with Shimano's cup-and-cone ball bearing hubs, they deliver a quick response and exceptional stability during any ride.
