I have a 2001 TREK 8000 HT with Rock Shox Sid SL fork, Avid brakes, and a mix of Shimano Deore LX and XT componets. I love the bike, it fits me great, but it shifts terribly even after tuneup and the brakes are shot. The componets just seem tired to me. I was just considering an overhaul of some degree to get her up and running so I can hang with the pretty bikes. does any one have any suggestions? I don't trust my local shop because they do sub-par service work. I am avoiding buying a new bike right now but if you think that is truly my best option than let me know please. Thanks.
