On the frame we have here, which is an S4, the BB height measures 13.75" which is just about 349mm. Listed BB height is 350mm. There are a lot of factors that can influence BB height. The tolerance on axle to crown height is +/- 5mm, tire wear and inflation, and tolerances of the frame itself all alter BB height a surprising amount. If you were to combine a bit of everything, I don't doubt on someone's bike out there it went up by 15mm. I think if they did a blind test they might find that that difference doesn't matter as much as they think it does on paper.
