The Chinook is an 11-Speed MTB middle chainring perfect for replacing the old one on your drivetrain for smooth and precise shifting. Unlike most common chainrings, this model has been cut in the traditional matter using a lathe which produces a superior tooth form for optimised power transfer and prolonged drivetrain life. Constructed from 7075-T6 heat treated aerospace grade aluminium, you'll benefit from super fast and accurate gearing.
