In case anyone else has this issue now or in future. I recently bought a used Mason Definition frame from eBay. It was one of the original, post-mount frames, and I wanted to fit Campagnolo H11/Chorus. The calipers are flat-mount only.

I also looked into using a Magura or Hope caliper. Then, I came across this website: https://www.assolutions.ca
