whilst we are on the topic how do you measure bb rise ?

Tie a piece of string/something straight between the two wheel axles, measure distance between bb and object between the two axles.

Say it was 60mm from the string the bb is +60. In some cases outside trials you can find negative bb heights.

Crucially it's the centre of the BB shell.
