    Pretty tiny, you could work it out with a bit of geometry but at a guess it would be ~1mm

    Pondering the idea of slackening out my Rocket at some point. Is there a quick rule of thumb for working out how much extra BB drop for each angle of slackening?

    Seem to remember some free online frame design tool that let you enter frame measurements and angles and play with them but can’t remember the URL?

    It’s about 2mm BB drop per degree off the head angle (if the lower cup has the same stack height).
