Whoops, yes I was and desperately trying to remember where I got to. I certainly haven't recorded anything. I did measure the Xtreme hub and meant to measure the Sierra later and never did. I believe with my vernier I did measure them and they were very within a gnats c---, but my depth gauge wasn't ideal for the job and I didn't have time to take them into work to properly measure and check. As we are only looking at small variations they did need to be acurately measured and I never did that. A long winded way of saying I don't really have any meaningful data. Wait I do remember borrowing a micrometer from work to measure the land between the inner and outer bearings, the Xtreme was identical to the Sierra. I hate posting bits of information, but this is all I can remember. Nigel
