Personally, I've never had good luck at Performance. I've been to a few stores in VA and one in DE. They truly are the Walmart of the cycling world. Just recently, I had a fit done, which required a new stem. The tech at my LBS "discovered" the only things holding the carbon fork and frame together were the headset bolts. Apparently, there is some other piece that is supposed to hold the parts together, which was NOT even connected. Unfortunately, I can't recall what this part was called, but I'll find out and report back. I purchased this bike at Performance.
While I never had a problem, the tech did tell me I'm lucky I didn't find myself with a cracked fork.
Most of the techs I've seen at Performance are pretty young guys and judging by things like this, they probably haven't had much training, either.
The above being said, they have tried to make things right and fix stuff, and I've just pretty much washed my hands of them. It just isn't worth my time.
