I have an '05 Trek Fuel EX-8 with a long cage Deore XT rear derailuer and have used it regularly the last 2 1/2 years. The problem is after a few LBS tune ups and derailuer alignments the rear gears still want to "walk" or shift when they want. I have replaced the chain and the rear casette already and was thinking maybe the new "Shadow" XT Deore would solve the issue. http://bike.shimano.com/publish/cont...GS.-type-.html
Is it worth replacing or rebuilding the springs etc. at this point or for around $80 getting a new one? I was looking at the Park site and they go into rebuilding them but I am just so sick of the constant mis-shifting that I could scream
Thanks for any help here!
