    brake adapter

    Hi there. Hoping someone can help me out and guide me to a store for the part I'm looking for. I just bought some Formula B4 brakes off of ebay. I should have paid more attention to the fact that they were IS mount. Anyways, my frame has IS on the rear but my fork is a Fox and has post mount. Does anyone know what adapter I need to fix the brakes to the fork? I'll be running a 160mm rotor but could get 180 if that would be the easiest solution.

    Nice find! I've been finding a few different ones and have been emailing companies just to make sure it will work. That KCNC is nice. Everything they tend to make is nice and blingy!

    You will have to increase the size of the rotor when using a post mount to IS adapter.

    Edit: Never seen the KCNC adapter before. I know many years ago there was an adapter that allowed IS caliper to be mounted to PM forks and retain a 160mm rotor, but it did not work with all calipers.
