    How do you measure Bottom Bracket width?

    I'm selling the Afterburner crank off of my 2011 Scalpel. How do I measure this for the ad?

    Yup! I have the manual. "FSA Afterburner 386 BB30, 42-27", is what it says, but it doesn't tell you which bottom bracket width it will fit.

    Your Scalpel has a 73mm BB shell width, but the crankset will also fit 68mm BB shells, you just need additional spacers...

    Thanks so much. That's exactly what I needed.
