thanks for the info, but how did you choose the new bottom bracket when you swapped the crankset? is it a regular double crankset road chainline value?
Regarding the change of shifter, was there any problem to set up the thumb shifter instead of the gripshift-like shifter? Nice car btw!
I can check at home the original BB.
When I replaced the crankset, I had put a regular 109.5 mm DA 7700 but it was too short.
I've replaced it by a basic one: now it's a bit too long :D
I'm looking for a 7703 or 6503 (made for triple cranksets).
The models with internal-gear hubs come with:
My model, Katu 30, has 5 speeds.
The katu 20 has 8 speeds.
The chainring I have now is 46T, and it's OK for Paris (I mostly hang around between the Seine and Clichy).
