The new GRX wheel makes gravel rides faster, farther and more fun. Wider tires need wider rims to maintain the tire's lateral stability at low air pressures.
Shimano studied the complicated relationship between tire size, width of the rim, air pressure and lateral stiffness of the tire, to optimize the width of the GRX rim for 32-50c tires. In addition, we seek the best balance between weight, resistance and rim profile, to offer an exceptional gravel wheel.
