No bike store in Pittsburgh will match Pro Bike's breadth and depth of bikes and accessories; however, while its employees are quite knowledgable, they are generally rude and inattentive. On the bright side, you'll get the service you deserve if your intention is to buy a serious bike. Casual cyclists should visit BikeTek down the street.
What other shop carries a carbon fiber fat bike? This store has a great selection of cutting-edge technology. At the same time, there is a certain amount of discounted obsolete inventory that should intrigue anyone who falls somewhere between novice and die hard enthusiast.
Anyone who is halfway serious about cycling should definitely visit this store.
