Product Story

IS mounts are the type with the mounting screws that install horizontally. We make them in +0, +20 and +40. To figure out what size adapter you need, you’ll have to check and see what size rotor your frame and/or fork were designed for. For example: if your fork was designed to fit a 160mm rotor and you want to run a 180mm rotor, that is a difference of 20mm, and that’s the adapter you would need. Another example would be a frame that was designed to fit a 140mm rotor, where you want to run a 160mm rotor: you would also need a 20mm adapter.
