REAR WHEEL SHIMANO GRX WH-RX870-TL-R12-700C 11-12S CENTER LOCK

The new GRX wheel ensures faster and more fun gravel adventures, with longer distances. Wider tires require wider rims to maintain lateral stability at lower tire pressures. Shimano analyzed the complex relationship between tire size, rim width, air pressure, and tire lateral stiffness to optimize the GRX rim width for 32-50c tires. In addition, they sought the best balance between weight, durability, and rim profile to offer an outstanding gravel wheel.
