With a dizzying array of standards, drivetrain compatibility has the potential to be an annoying aspect of mountain biking.

Finding the best chainrings for mountain bikes then mixing and matching with other drivetrain bits can feel like it requires an encyclopedic knowledge of component catalogs.

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.

Single ring drivetrains dominate the mountain bike market, but the technical feature that makes them work has limited compatibility. Those alternating profile teeth on the chainring help prevent chain drop, but they also hinder compatibility with chains.

Rotor’s design engineers applied themselves to create a range of different size and shaped mountain bike chainrings that would work with the broad spectrum of Shimano and SRAM mountain bike drivetrains.

Whether you use a Shimano, KMC or SRAM Eagle chain on your mountain bike, there is now a Rotor Universal Tooth chainring that

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.

Mounting options are direct or bolted, with sizes that reflect the generous gearing spread of contemporary 1x11 and 1x12 drivetrains.

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.
