I keep considering the Nitto stem from Compass, but that's a lot of money. Then it's another $200 for the custom decaleur (which seems outrageous no matter how you look at it) and then, because the new stem and decaleur have limited adjustment, I probably will have to replace my Berthoud bag too.

IOW I can get rid of the slightly bodgy drilled bell spacer for just under $700. So I probably will keep considering...
