I've got a sweet X0 drivetrain on the Muk but want a little more gear (30t front currently). Back in the day shimano made hg61 and HG400 12-36 9 speed cassettes. Anyone have one in a parts bin they wanna ditch? Still around new and used but not sure if the RD will work so would like to try it first. Yeah, I know it isn't that much for a whole 10 speed drivetrain but the X0 shifts like butta so would like to keep it. Thanks!
