Qu-Ax Muni and RGB compatibility

I am considering getting qu-ax muni, but eventually I would like to put a nicely coloured RGB frame on it.
I know they are quite different, but will the Muni hub fit on the RGB?

I’d think that the bearing centerline distance and bearing diameters are what you’d make sure match. When I built my RGB unis I matched those up accordingly and had no issues. Had to use a shim for the 40mm bearings since the RGB frame is designed for 42mm bearings. But I knew that going in and it’s worked perfectly.

If it is an ISIS Qu-ax muni, it also sports 42mm bearings so no shimming required. And for square-tapered hubs, anything would do as shim (from real shim to drink can cuts :yum:)
