    Itíll need 20mm more that whatís there now. If no spacer now, itíll need a 20. If 20mm spacer now, itíll need a 40.

    maybe wrong terminology. but can you just use the spacers on the bolts or do you need to add the new piece between the fork and rotor?

    you will buy a specific 180-203 post adaptor and then another 160 to 180 post adaptor

    They come with the extra bolts required
