Sram HRD flat mount caliper (becomes plus 20mm)

Cairn brave fork with post mount

ah easy fix - wolftooth flat to post adapter 🙂

Nope - it fouls the post mount setup!

any other ideas?

Post-mount caliper. I'm both being flippant and serious. Flat-to-post adapters are always such a bodge and highly dependent on the shape of the fork mount.

I had exactly the same issue with flat mount shimano calipers on a post mount bike, and bought that wolf mount. I also couldn’t make it work - it just didn’t fit, so sent it back and ended up with different calipers, which was a pain in the arse but the only way I could solve it
