    Bottom bracket measurement question

    A dumb question, but is bb height measured from the spindle centerline or the bottom of the bb shell?

    Even spec sheet diagrams are confusing. Check out Santa Cruz or Orange sites, looks like they are measuring at the TOP of the shell?! Spindle centerline seems the most logical though. Thanks for the quick replies!

    the Orange one has the line right through the center of the shell (line E), the SC one has the vague line towards the front of the bike, but the measurement is standard so...
