Hi..
having now replaced my forks, its evident that my M4 IS mount caliper wont fit. Currently have 180 disk installed, have a 183 floating rotor available.

What do i need to purchase in order to us this IS M4 caliper on a Post mount fork, happy if i need to replace the disk.

all advice welcomed

    yes the IS mount caliper have a number on them which defines what size they are.

    is it a 3? or an 8 or a?

    if you have no idea post up a picture.

    well you have problems.

    if you can get a KCNC post to IS 160mm adapter you can use that.

    otherwise you will need a normal Post to IS adapter which will need a 203mm disc.

    cheers.

    just to be clear i have a 180mm rotor fitted currently - that would work with the KCNC 160 adapter ? or do i need a 180mm adapter?

    Or buy a Hope Mount Adaptor Front IS to Post +20mm which means i have to replace the rotor ? would that be a 200mm or 203mm ?

    dont want to order the wrong bits ?
