On my '06 Stumpy I've got the stock Shimano M-750 XT rear derailleur. I can adjust it but it doesn't seem to hold the adjustment for more than a week. Even when I get it pretty well adjusted it still will skip a gear when I really get on it.
I want a system that works well all the time that doesn't require constant adjustment. Does upgrading the derailleur system to something better make for shifting that is spot-on and reliable?
Thanks for any suggestions. I take this bike deep into the wilderness alone and really want something dependable.
