I'm not certain, but I think 120 indicates that these spindles will position the crankset to achieve proper chainline with a 120mm / 5-speed rear hub. It's all a little wierd though, because as far as I know Campy never simultaneously made different spindles to work with 120mm / 5-speed and 126mm / 6-speed rear hubs. They made the 68-SS-120 (or 74-SS-120) then they added some length when the CPSC changes were made about 1977. These were marked 68-SS-120 along with +1.0 / +1.5. Later they were just marked 68-SS. By this point the standard for rear hubs was 126 and the post-CPSC BB's are suited to such use. In any case there are definitely pre and post-CPSC spindle differences, and one would be lead to believe that there are also 120 / 126 spindle differences, though none of my observations suggets that this actually happened. In other words, if you have a pre-CPSC crank use a pre-CPSC BB and it should work with either 120 or 126 rear hubs. If you have a post-CPSC crank use the newer BB and it too should work with either type of hub. Confused yet?
