Before I make any calls, regarding the Cambio Rino, I would have to see pictures of the bicycle and know the width of the bottom bracket housing. Cambio Rino bikes sport inconsistent quality, some being just great and others being poorly made. I have even been told that the manufacturer did, at times, cheat on what bikes were made of.
Put another way - be very careful when choosing a Cambio Rino.
This particular one had unequal length stays, one side being longer than the other...
To that add that the bikes were offered in a range of quality levels, from
entry level...
to
fairly high end...
Hope that is a help.
