I have a 1984+ Ciocc Designer 84 and am going to use 1980's SR cranks, so post CPSC. 70 mm bottom bracket. For some reason I have 111 mm stuck in my head. However, after I look at Velobase I am more confused. Last bike I set up a few years ago was my Merckx with C-record cranks and 8/9 speed (lol I can't remember how many cogs. Sad really). Is 111 mm for C-record? Velobase doesn't have Italian BB listed. They just say add 1 mm to BSC or French which would put it at 114.5 + 1 + 115.5 mm. Is this the correct width I should be using?
