    What do I need ? Older IS tab fork

    Hey guys I finally upgraded my front wheel on my bike and I need to figure out what brake adapter I need to use ... I got a centerlock wheel so I will use shimano for the brakes ... I have nothing yet just the wheel and rockshox sid fork with tabs not post mount...

    Any help would be awesome guys !

    What if i have the opposite problem? It's not the same is it?
    I've upgraded my fork which has postmount setup, but still have the old IS shimano XT's calipers.

    PM fork + IS brake = same or SOL?

    There is adapters to fit IS brakes onto PM forks, they are different to the adapters I linked above, they don't work with all IS brakes and they don't work on all PM forks .

    What model brake do you have and what size front brake caliper do you have ?

    I've got XT hydraulic from around 2002/2003.
    Should be for the smaller rotor, maybe 160. do you know if this might work?

    If you have a 160mm BR-M755 then you can get an adapter but you'll probably have to use a 180mm adapter and upsize to a 180mm rotor.
    The design of that model caliper means that it probably won't work with a 160mm adapter

    160mm caliper + 160mm adapter + 6" post mounts = 160mm rotor
    180mm caliper + 160mm adapter + 6" post mounts = 180mm rotor
    160mm caliper + 180mm adapter + 6" post mounts = 180mm rotor
    180mm caliper + 180mm adapter + 6" post mounts = 200mm rotor
