I've been here a number of times since moving to Pittsburgh, for miscellaneous parts. They are always very helpful, and I often end up in a longer conversation than I expect, if the staff isn't busy. They carry a pretty wide range of products (Trek, Kona, SoMa, Velocity), even some inexpensive stuff which has kept me from ordering online (tires, fenders, and pedals for my used commuter bike). They never push me into more expensive parts, possibly because even their cheapest stuff is of good quality. I guess the one thing keeping it from being 5-star is that it is part of a chain and lacks that intimate feeling that independent shops have.
