I have a Specialized cyclocross bike (the Tricross) which has "Forged linear pull brakes w/ cartridge pads". These are really cool, as they are so easy to adjust and keep aligned to the wheel (the multiple concave/convex adjustable washer setup on the more basic brake shoes always get the best of me). However, i'm new to cartridges and see references to Avid style and various Shimano styles. How many different cartridge designs are there, and how can i know which mine are? The pads are getting a bit worn, and i'd like to put in some Kool Stops pads, if possible, anyway.
Thanks in advance for your help.
