Quality is one of the major bike part distributors. In fact they also own Salsa and Surly. Many local bike shop websites will have a function where you can search out parts and accessories, and within that list is an huge database of parts.....most of which are not stock items at the store....but rather rough estimate of what is actually in stock at Quality.
