Thanks. Yes, that's right. I was just a little confused because, by my calculations, I'd need a 111mm-ish bottom bracket for a 42mm chainline, so sought some advice. I would have thought I'd get a 40mm chainline with a 107 bottom bracket.
Anyway, as you say, I'm probably overthinking it. I might just get the Xpress cranks and shove 'em on my current bottom bracket. May as well keep it until it's knackered. From what I've read it's JIS so it should be fine. If chainline turns out to be a problem in practice, I'll upgrade then!
Thanks again.
