Use this hanger kit to make your new or existing Boost Chumba Frame compatible with the new SRAM Transmission Drivetrain (T-Type for short). These should be paired to a 55mm chain line crankset for Boost 148×12 MTB and a 52mm chain line for standard 142×12.

If you order a SRAM Transmission from us, we will include the insert set for free! Note the silver inserts are samples, they will ship as black.

Included also is a Wheels MFG rear axle, please let us know if you need Boost 148×12 or standard 142x12 in the order notes.

Does not come with the 4 main bolts. You can use your existing hardware for that.
