GRX

Built for Gravel

GRX wheels for gravel and mixed surfaces deliver stable handling and efficient performance.

Purpose-Built Carbon Profile

SHIMANO refined the balance of rim weight, strength, and shape to create a carbon wheel tuned specifically for gravel. The result is a responsive, efficient ride that stays composed over long distances and mixed terrain.

Stability At Lower Pressures

GRX wheels are designed around the realities of gravel riding, where wider tires and lower pressures improve traction and comfort. The optimized rim width helps maintain lateral tire stability on loose, rough, and changing surfaces.
