trying to hard there....
but back to the OP question. I would also like to re-suggest bike revolutions on 4th and bainbridge for any fixed/single speed bike work, bryan really knows what he's doing as is a great guy. bikeline is also good and if you get a complete bike from them, for an extra 50 bucks or something they will perform any work on it for 2 years? for free. tune ups, flat tires, truing, etc.
welcome to philly
