I have a gran sport strada chainset that I'm planning to mount on an 80s basso frame.
I was in an lbs today asking about bottom brackets. They seemed to think that my chainset would require a special, asymmetrical bottom bracket to hold the chainset in the correct chain line. This was they way the gran sport system was set up they said.
Does anyone know if this is true and if so, what my options are for a bb?
All sounds quite limiting and potentially pricey..
