With their optimized tooth profile, the GRX 1-speed chainrings keep the chain in check even under the toughest gaits. When driving off the beaten track, conventional racing bike components quickly reach their limits on Gravel bikes. Therefore, Shimano has developed its own switching groups for the special requirements in rough terrain for this genus.
The GRX chainrings made of lightweight aluminum, are very solid designed to increase the torsional stiffness and thus the durability of the forces occurring. To better address specific Gravel needs, finely tuned translation options with tighter pitches ensure a regular and fatigue-free pedaling rhythm.
