Paul I.S. & POST MOUNT DISC ADAPTERS

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.

Please don’t call us asking what size adapter you need, we just don’t know what rotor diameter every frame and fork out there were designed for, so you’ll have better luck asking the frame manufacturer themselves, or your local friendly bike shop.

The post mount version works the same as IS, except the caliper mounts to frame or fork directly through the caliper holes, instead of at a 90^ angle.
