matt rushton Posted January 7, 2006 Report Share Posted January 7, 2006 the bb rise is the rise from the rear skewer to the bb and its in mm so if its 20mm rise it rises 20mm up to the bb. hope that helped Quote Link to comment Share on other sites More sharing options...

The distance above (or below!) the line that the BB sits (centre of the axle) is the BB rise.Jon Quote Link to comment Share on other sites More sharing options...
