Has someone successfully done that upgrade, and could offer some feedback (bottom bracket, clamp, derailleur, double crankset)?
Thank you.
Are there spacers on your bottom bracket? If so, how are they arranged? These photos show that the Birdy Rohloff (white) has no spacer on the left side whereas the Birdy City (blue) with 9 speed derailleur has a spacer on the left side. Both bottom brackets are the same length.
