Ok got a set of mono M4's that are IS mount and 200mm rotor. New forks are going to be post mount, is there an adaptor that will allow me to keep the same size rotor and use the IS caliper. From memory I think A2Z may do one, the hope one you need a +20mm rotor, not a problemif I was runninf 180mm but as it's already 200mm I'm a bit snookered 🙁

thanks

KCNC do one but it doesn't seem to fit all forks. I've got one which might be spare as it doesn't clear my fork leg.

Have a look here.

kcnc one doesn't work too well with my PM fox floats, had to file it down and space it out and use a slightly bigger rotor (180mm calliper, spaced out then use a 185mm disc)

you used to be able to get 220mm discs, worth a shot if you like big brakes 🙂

I think these may help:

To run a 160mm caliper and 203mm disc

I used the second one with a magura 180mm IS caliper to run 203mm discs but had to shim it out 1.5mm to fit the 203mm rotor as it is designed for 160mm calipers on 180mm rather than 183mm discs.

Hope will do you a custom 220mm rotor if the adapter doesn't work out.

I did a caliper swap with someone when I had that issue.
