I'm trying to replace a 9 speed, xtr m970 11-34 cassette on a DT Swiss hub with the new shimano 12-36 cassette. With the 11-34 cassette, all is well, with the 12-36 cassette on there, the freehub doesn't spin when I clamp it in the dropouts. Put the 11-34 back on, all is well again.
I'm fairly certain the new cassette is seated fully on the driveshell, and I've tried both loosening and tightening the new 12t lockring.
Anyone have any ideas for me? Thanks!!! :-)
