160mm disc on 140mm fork

Paul 8v

I've got a cannondale with a fork designed for a 140mm rotor and I want to run and 160mm one. I can't find an adapter anywhere.

Is it just a "180mm" one like the below as I assume most of the standard fork setups are 160mm and I just need to make it 20mm bigger?

If you have PM forks and PM calipers, yes.

Thanks cooldad. It's the last piece of the puzzle to get it on the road!
