Oh right, well I must say that I didn't check the details of the bottom bracket besides it mentioning iso towards the bottom of the page on the link. No, I'd first heard the opinion of a chap on the Cycling UK (CTC) site, and the guys on there seem pretty savvy on such matters and were specifically discussing iso square taper bottom brackets. Anyway, now there could be some doubt I decided to have another look. The guys on there only referred to the First Components bb once, but another iso taper design the brought up several times were older Miche models. This caught my attention as they'd mentioned that some of the models were still made today but that in more modern times the axles had been changed to jis taper. That made sense to me (what with iso having become less popular in recent times) and what seemed to be reassuring was that the older ones were apparently stamped 'ISO', and because they were discussing it I think it's likely this means it's iso taper and not iso threading (and there's also the fact that many European companies were making iso taper bbs at that time, and of course Miche is European). Actually this was quite pleasing news because I happen to have a few of the Miche bbs and know that none of them are from modern times, so will now check which ones have the ISO stamping. And whilst I'm at it I can also measure the axle lengths for a possible 103mm length if you'd be interested?
