mine is 73 with a spacer on the drive side.
I originally had spacer problems and contacted Ragley way back when. Seemingly, the early model had one size BB and the later, more common model had the other (I forget which way round it was but I think I had the latter, which is 73, and the earlier one was 68).
After my contact, they corrected the spec list, but the correct spec list is now lost since the frame isn’t made ie dont trust any specs you find online as they won’t necessarily be correct.
