Looking for a disc brake adapator for a Hope Mono Mini with IS mount and I want to mount it onto a post mount fork. Rotor size is 180mm. Anyone know where to get one? I looked on here but couldnt see one going from post to IS only the other way around….

Can't do it and keep the same rotor unless you change the caliper half.

What size rotor should it be then?

200, if it's an IS Caliper & Post Mount fork, you have to add 20mm to the rotor size to allow for the adaptor

So I cant get an adaptor that will fit a mono mini to a post mount fork with a 180mm disc?

Mono Mini is post mount, so surely you need post to post

THis is IS mount with a no 3 caliper

If it bolts to on IS fork & uses a 180mm rotor, when you swap it to a PM fork & need an adaptor, you'll need a bigger rotor by 20mm as well. The adaptor spaces the caliper further away from the fork, resulting in the need for a bigger rotor.

I have a +20mm adaptor for sale, it was on classifieds last week (hope HBSM20H) but as already stated, you're need a 200mm rotor if you are currently running 180mm. It's yours £7.50 posted.
