I bought two bikes from them during the 5 years I lived in Pittsburgh. Some say they are overpriced but I never bothered to comparison shop, so I wouldn't know. They appear friendly but I think they are generally very incompetent. The actually sold me a Gary Fisher bike with the fork fitted backwards (so that it curves back instead of front). The bike always felt unstable but I never realized the problem. The worst part was that I took it to them for a tuneup every year and they never even noticed the screw-up themselves. I only noticed it after I left Pittsburgh. Anyway, their tuneups are a waste of money. The bike never felt different after a tuneup. Don't know what I was paying for.
Cons: Not very competent
