On one like this, where it's described as 68mm x 113mm, what's 68mm? And I presume 113 is the width of the BB, but is that precisely from one external 'face' to t'other? Or what? How many different kinds are there? (I'm looking for something to fit an old British frame - is there a 'standard' it's likely to be?)
