Well, I got my DT finished and have rode it a couple of times. (I'm iced in at the present) I noticed that my chain makes quite a lot of noise even though the derailleur is aligned perfectly. (took it to my bike shop and they helped me set up the derailleur and brakes) So, I put it up in my stand and looked very closely and realized that the XT shadow has a guide that the chain rubs against when it goes from the first cog to the second. It's like the guide doesn't allow the chain to travel a straight path from one to the next. The XT has and adjustment that lets me move the second cog closer to the sprocket but I don't think it'll change the rubbing on the guide. I'm thinking the guide will wear my chain out very quickly. I guess my question has to be... Is this normal or can it be adjusted out better so the chain doesn't rub the guide?
