Sorry for this new to REDDIT. I posted the wrong chainset and I can't see how to change it (I picked up two bikes one which is AutoMoto). This is the complete bike . Not sure about the handlebars either. In terms of the bottom bracket does it use a special tool or is it a standard spanner . Thanks for the help so far – i'm renovating two bikes for the Anjou Velo Vintage at the end of June. I think its earlier than 1960's. The saddle is absolutely fantastic
