Hi Adrian,
I run A10's with both types of brake cables and have found that very few suppliers can get it right when I am ordering spares even when quoting the correct part numbers. I should have made a note of the individual lengths but like a jerk, I didn't.
Anyway, I have a spare later type (bottom pull) cable and comparing it alongside the earlier bike with the top pull I find that the earlier type cable is longer.
The earlier outer cable is longer by about 1 1/4 inches (32mm) and the earlier inner cable is longer by about 2 1/2 inches (64mm).
This is as accurate as I can be without removing a cable and comparing them laid on a bench.
Hope this helps.
Beezageezauk.
