I have mentioned swapping disc rotors. The sharper tacks amongst you will notice im using a 180 rotor with an 185 avid adapter/BB7. Isn't that a bad idea? especially if the pads wear and then hit each other before they hit the disc because 2.5mm of the pad material never gets worn by the rotor?
Well, it would be, but i used an end mill and removed some material from the adapter to allow a good solid contact.
