Super Record 1985 - which bottom bracket?
I know this has been discussed many times, but I haven't found an answer.
I have a Super Record crankset from 1985, the original bottom bracket (probably Nouvo Record) had an asymmetric spindle with a length of 114.5 mm and according to velobase this crankset needs 112 mm. On the other hand, according to the often quoted Campa paper on bottom brackets, the Super Record bb then had a spindle of 112.5 mm and the Nouvo Record 115.5 mm. Now that I want to buy a modern BB that will fit this crankset, I have two questions:
1. According to my calculations, I need a 119 mm symmetrical BB. Is this correct?
2. Camapagnolo used its own taper back then. Should I buy a JIS or ISO bottom bracket?
