ROTOR BCD 100x4 chainrings and INspider® MTB cranksets incorporate Universal Tooth technology, which guarantees compatibility with 1x12 and 1x11 Shimano® and SRAM® Eagle® chains. This allows for perfect chain engagement, optimal retention and low friction while keeping the weight of the assembly very low. Rotor now offers 30t, 32t, 34t, and 36t options for every type of riding.
If health and performance is important to you, ROTOR's Q RINGS should be your choice over round chainrings. Our oval chainrings allow you to pedal more efficiently, making the most of the power developed during your pedaling. With improved traction on uneven terrain, oval chainrings reduce stress on your knees resulting in healthier pedaling.
