1976 benotto bottom bracket options?
I purchased a '76 benotto, and have been disassembling it to ready the frame for cleaning and possibly painting. It has cottered cranks, one of which seems to be stripped or otherwise messed up in the channel the cotter runs thru.
I am new to Italian (via Mexico) bikes, and particulary to bikes of this era. Would I be best served by replacing the bottom bracket/cranks/etc. (can I use a modern sealed BB?), or are there options that would allow me to use the existing BB, with more modern cranks/ring. This bike will be an addition to my fixed gear fleet, but will most likely not see alot of abuse... that's what my commuters are for.
Thanks for your input. Searching specific to benotto's didn't give me any leads.
