Mountain Disc Boost Rear Hub
Just when you got comfortable with 142x12mm, the industry decided to show you the benefits of Boost! By moving the hub flanges out 5mm on the 148x12mm rear hubs, Boost helps provide added stiffness to larger wheels while maintaining Q factors.
Our Mountain Disc Boost rear hub comes in at 280 grams. Coming with your choice of Shimano 11 cassette body (includes a spacer for use with 8/9/10 speed systems) or a SRAM XX1 cassette body. 32 hole versions.
