Not the Paragon dropouts but the new cast ones from Nova etc. See pic below. I initially tried to install a set of the Paragon dropouts but for quick release on my 89ish Raleigh Peak mtb. I tried to weld them on before taking a frame building workshop. Once the workshop was finished the the Peak got set aside. I bought the cast dropouts to use on a new build but did not like them. I was between frames and as I had everything needed to convert the Raleigh to 27.5 I decided to try to fit the cast dropouts. It is a slow build and I needed to figure out the cable routing.

This is the Raleigh Peak 650b disc conversion
