Sorry fellow members. I may be showing my ignorance and need enlightening.
Question !! Is there a universal standard for rear track spacing, whether Brittish, Italian etc. I'm selling off my 79 Holdsworth track bike. Rear spacing is 110cm with Shimano hubs, single side fixed. The buyer has vintage Campag Record of approximately the same era that are single sided fixed, atleast that's my understanding and they are spaced at 120cm. My 1972 Hetchins track bike is spaced in the rear at exactly 115cm, with a Campag Record single sided fixed high flange hub. In case anybody is wondering I've double checked all measurement for correctness.
According to good friend Keith Helon, most single side, or double fixed are 110cm, and fixed/free are spaced at 120cm.
If more modern bikes did start spacing at 120cm for single sided fixed, when did this come about ?
