Thanks to rodders and NivagRD for their help on two of my cables.
I've now just got one GREY front brake cable left to id. I think that it is off a 1973 to 1975 RD60 (and maybe Euro RD50) and was wondering if there is a RD60 owner here who could confirm their cable dimensions. The details on mine are as follows:-
Outer diameter of cable cover - 6mm
Length of cable cover, between outer sides of ferrules - 970mm
Length of inner cable, between outer sides of nipples - 1080mm
There are no extra layers on the outer cover, to protect from chafing.
Many thanks.
