Made for the gravity riders and the long travel hero. The 9 is forged from high grade 6000 series alloy with reinforced cross sections to be as tough as it possibly can. Coupled with a length specific M30 spindle... Just one look at the 9 and you know it's made for purpose.
BB - Majority of DH bikes are based on threaded 83mm width BSA, but occasionally some brands use PF41 x 104.5, and PF41 x 107. The good news is we support the installation of the 9 in all three of these DH frame types with our M30 BBs.
