Rotor Q-Rings Inner Chainring for Shimano GRX - BCD 80x4 - oval

Rotor Q-Rings – Ride further and faster with less fatigue

Thanks to their oval shape, Q-Ring chainrings allow for more efficient muscle use and increased cycling performance by varying pedaling resistance according to the legs' natural strengths and weaknesses. Because the smaller diameter of the oval is oriented toward the weakest point of the pedaling stroke and the larger toward its strongest point, the most productive part of the pedaling stroke is optimally utilized and the time spent on the less productive part is reduced.

Oval 4-arm chainring for Shimano GRX 2-speed cranks with 110/80 mm bolt circle diameter. Made from CNC-machined aluminium 7075.

The inner chainring is available with different teeth counts.

Weight: approx. 31 grams (30 teeth, weighed by Bike24)
