Rotor wants to make it easier and is now offering a range of Universal Tooth chainrings. The company promises that these new Universal Tooth rings are will pair with any Shimano or SRAM 1x11/1x12 mountain bike drivetrain.

Oval chainrings are a crucial part of Rotor’s business, offering its Universal Tooth design components in both round and oval shapes for all sizes and mounts options.

Riders who prefer a direct mount oval ring can have the new Rotor Universal Tooth chainrings in 28-, 30-, 32-, 34-, 36- and 38t. The BCD110x4 mount option is available in 34-, 36- and 38t profiles.
