I use a 12-36 cassette with my 3x9 Shimano drive train for wall climbing but would like to lose the weight of the cassette. Since there are no light weight 9 speed 36 cassetts I could go with an XTR 34 if I could find a 104bcd 30t middle ring and retain the same low gearing. My crankset is the XT m-770 triple. Anyone know of a good 30t replacement middle ring? Thanks for the tips.
