Hi,

I am looking into getting a new BB and I'm getting a bit confused with the measurements. From what I understand the BB size is the width of the BB as well as the length of the shaft that sits inside it. I measured the spindle length of my current BB and it is 135mm! I did the measurement again and got the same answer, but this seems to be 10-20 mm too long. I then looked up my current crank specs here:

and it says BB length is 117. I don't get how this can be. The BB and crank are stock with the bike as far as I know (I bought it 2nd hand)
