"Wolf Tooth Components" is a group of hardcore cyclists based in Minneapolis who create unique cycling components. All items are designed independently and produced in the United States.
Chainring for XTR M9000 and M9020. Threaded for optimal chainline. Do not use anything other than Shimano's exclusive chain bolts. Wolf Tooth's patented Drop Stop Tooth prevents the chain from falling. 10S, 11S, 12S (including SRAM Eagle) chains can be used. If you use a 9S drivetrain, use a 10S chain.
