Review: Store looks bigger than their Rockville store, but there is a lot of empty area. Lots of bikes, decent amount of kit, seems to be the same gear found in the other store.
My positive review is due to walking in and not really being sure if I'd find what I needed. They not only had exactly what I needed (last bag, too), but they were more than willing to look in their parts bin in case they didn't have the product.
Great shop. If you are in the area, definitely stop by.
