dont bother with the odd cassette they also skip and if u run ur chain tight they end up blowing the driver bearings, wait a few months (for the 48 hole, 36 hole will be sooner) for the new gsport hub, this uses needle bearings in the driver so u can run a tight chain without the bearings blowing up and has been designed to eliminate skipping and can be used for lhd and rhd with no other parts needed
