I just got a close to brand new XT Shadow rear derailleur installed a few weeks ago to replace a LX that honestly never gave me a problem. Got the new one for 35 bucks. So far I have had no luck getting the damn thing adjusted to shift right. It is ghost shifting, skipping,and you name it. 3 different bike mechs have worked on it to get it right, still not there. Are these things total crap, or is it just me. I would love to hear from anyone who is using the same thing. I am ready to go back to my cheaper LX at this point.
