While the drivetrain brands prefer you run their complete setup, and indeed have put a lot of time and effort into optimizing their systems to be run “on brand” from tip to tail, sometimes we just like to have options.

And Rotor’s carbon and alloy cranks are some very nice options. Now, they’re offering new Universal Tooth Design chainrings in round and oval shapes that they say are 100% compatible with Shimano and SRAM 11- and 12-speed mountain bike roups and chains, as well as KMC chains.

The chainrings are CNC machined from 7075 T6 alloy, which they say is durable enough for thousands of kilometers of trail riding. They’ll come in the following sizes and options for direct mount to Rotor’s cranksets or standard 110×4 BCD spiders:

MTB Q RINGS
• Direct Mount: 38/36/34/32/30/28
• BCD110x4: 38/36/34

MTB ROUND RINGS
• Direct Mount: 38/36/34/32/30/28
• BCD110x4: 38/36/34

Just look for the little chainring-tooth-in-a-circle icon on the backside of the rings to confirm you’ve got their new UTD tooth profile.
