According to the info on the B/B (and on the picture I've posted), there's reference to '68' and '113'. Is this the shell size and the axle length? I'm no expert on these matters...
yep, that sounds right - if there's absolutely no play in the axle I'll offer you £14 for it. They're getting harder to find so a spare is probably a good idea. I did buy one advertised as good but it had noticeable play so I'm being cautious.
Thanks,
Jim.
I've just double checked the axle and don't detect any play at all. Have you checked the pic to make sure this is definitely the B/B that you want? If so, I'll send you a PM with relevant info.
