[#1462266]

I have some original hope mono minis, the black and gold ones, with an IS front caliper for a 180mm rotor.

I now have some post mount forks and want to run them on them but cannot find any adaptors that do not increase my rotor size. The hope adaptor means i have to run +20mm which would be a bit excessive for what a want and would look ridiculous.

Is there a better way???

Nope. you have to go up 20mm otherwise there is no space for the adaptor.

Having said that, it your calipers are anything like my old C2s, you can get another caliper half with the correct mounts (athough that does mean a rebuild and bleed of course).

I thought that but they are mono minis so are a one piece machined bit. Guess a wanted in the clasifieds is the way to go....

I'm using an adaptor on a set of forks at home which does this... but despite trying, haven't managed to find another! Was kinda lucky as it came secondhand with a fork off the classifieds on here...

Will have to take it off and see if it matches anything available...

You need a post mount mini calliper. Thats what I had to do. fortunately as they are hope all are interchangeable and the pads are the same so you don't end up with any incompatibilities
