Since this seems to be the Denver LBS thread, I want to mention Creekside Bikes out in Parker. It's a tiny place that I stumbled upon kinda recently, on Parker Rd and Pine Lane (by Bonaroo Tattoo).

I've been going there with my problems for a few months, and Kirk has been taking good care of me. He also has a lot of vintage bikes and jerseys hanging up and a Campy shrine full of shiny old components.
