    can you help clarify which mount

    I dont know why Im having issues understanding what mount to use but i am.

    Im building a 07 yeti 575, im using a 2012 fox float front fork and avid ultimate brakes.

    Im planning on 180mm rotor on the rear and 160mm on the front but im not sure which mounts i need and have been searching the web.

    Seams im just getting confused so hope you guys can shed some light.

    Thanks in advance..

    Does the frame have post mounts or international standard? Your fork has post mounts, for reference. You would not need an adapter for the back if it was a post mount (but would need a 160mm IS adapter if you have IS tabs) and would need one for the front (a 180mm avid post mount adapter).

    Any particular reason you want the smaller rotor in front? The usual is opposite that, as you would usually want more stopping power in the front.

    The other way around would be better.

    The front has more stopping power then the rear.

    160mm on the front = no adapter
    180mm on the front = 20mm Post adapter in the following photo.

    160mm on the rear = 20mm IS adapter in the following photo.
    180mm on the rear = 40mm IS adapter in the following photo.
