My post mount forks have clearance for 140mm rotors and I'd like to use 160mm - what adapter do I need, all the ones I seem to find are postmount to IS...

Any ideas?

postmount to IS

No, those are like unicorn poop

Most will be IS to PM, because until recently sensible frame builders still used IS mounts even though IS calipers are pretty much all gone now.

You need postmount 140 to postmount 160.

This might work - although it specifies it's a rear post-post adapter I wouldn't have thought there's a difference?
Lots of 160>180 mm but I can't find any other 140>160 mm.
