Long have I thought that cables, from different times, might not be the same diameters. This thread got me off of my butt, finally. Having lots of old and new cables, both transmission and brake, I just went and measured. Here is what I got...
Shifter Cable Old - 0.057" = 1.45mm
Shifter Cable New - 0.042" = 1.07mm
Brake Cable Old - 0.061" = 1.55mm
Brake Cable New - 0.056" = 1.42mm
I used a 1" micrometer to measure and check several cables. These are my results and not, necessarily, to be taken as gospel. I might add that, over the years, brake and shifter cable heads have changed in size and appearance also.
