When I had my rear flat on Titanic’s maiden voyage and sunk an inch, I walked my bike to this store/shop. Luckily, they had a tube my size in stock. They don’t stock the store. All parts and bikes are donated. I paid $2 for the tube and $8 for installation. Their bikes are astonishingly well-refurbished. The showroom looks like a vintage bike museum. Some of you may know about this place; others may not. The proprietor told me she sees VBC members in there from time to time.
