I just got some very light work done on my bike (blown inner tube, needed a rack installed), and Frank was wonderful (note: he's only in on Sundays, but if you can get him, do it. He knows his stuff).
He was very knowledgeable, helped me make a decision about the rack I wanted to buy. Even though I looked at some panniers, he didn't mention anything about them when he rang me up, which was VERY refreshing.
Everyone else at the store was courteous and helpful. I will DEFINITELY be back here for maintenance and advice!
