i took my trek mountain bike in because the front sprockets were visibily worn. they ordered a replacement set and installed them.
when i test rode it (obviously they hadn't) the chain motion was very rough and so i then took it back and got the chain replaced. i believe they should have told me to replace the chain at the same time. again no one test rode it and when my wife brought it back after the new chain it slips badly on the two rear smaller sprockets so i am assuming that they will probably be need to be replaced as well. unfortunately i wont be able to take it to the Georgia mountains for vacation now. i think that when a bike is brought in for a specific complaint the mechanic should look at everything related to that complaint, and take care of everything needed, then carefully test drive it and then give it back to the customer.

Took an older Electra bike in to BW Northlake to get it tuned and ended up buying a new one to add to the family. The staff was friendly and knowledgeable and gave candid feedback and suggestions. I had to take the new bike back in because one of the accessories I'd bought came with the wrong parts (Electra's fault) and the guys sorted out the problem and installed the fenders for free.
