What length bb should I be using for a pomp with 120 spacing? currently got a 110mm bb with the chainring on the inside and its not quite right...

I believe RD2 needs a 103mm bb with the chainring on the outside for a 42mm chainline.

Sounds about right but that can be tight for spider/chainstay clearance with some frames, so you can end up having to go with something like 113mm and the chainring on the inside.

Thanks, sounds about right.
