Does anyone know for sure which adaptor is needed to fit IS mono mini to post mount fork? I have researched but confirmation would be good as not 100%.

Cheers

Looks like the one; but give Hope a call to be sure.

I used this one to fit a IS Shimano XTR calliper to a post mount fork.

Assuming mono mini is the same standard as XTR it should work but needs a +20mm disk

edit: oops too late!

I used one of these to attach a 180mm Hope IS mini to a post mount RS Reba with no need for an increase in rotor.
