big brakes (not blue/gold spots)

Has anyone fitted one of the later triple pot R1 brakes? if so did you make adapters.... if so... will you make me some!

Russ, are you referring to the radial mount R-1 Calipers?

I'm not aware I've ever seen an axial mount to a radial mount caliper bracket.
Anyone have any pictures? I can't picture in my mind what such bracket would look like.
