I have a Colnago C50 from about 2005 or 2006. It's got Campy Record 10 speed, with traditional 53/39 rings and 172.5mm cranks. I'd like to move to a compact chainring set-up. Does anyone know what my options are? Can I get by just replacing bottom bracket, cranks and rings? Or is there more to consider? I'm looking for suggestions and insight. Thanks in advance.
