Matt_Tupman Posted December 5, 2005 Report Share Posted December 5, 2005 The height above the wheel axle?? I think Depends thats how i always mesure it but i know some companys mesure it from the floor. I think most trials companies do it the first way Quote Link to comment Share on other sites More sharing options...

I think most trials companies do it the first way Yer maybe,. from the floor, and then take away the height from axle to flooor? Quote Link to comment Share on other sites More sharing options...
Matt_Tupman Posted December 5, 2005 Report Share Posted December 5, 2005 Yer maybe,. from the floor, and then take away the height from axle to flooor? Yeah i guess that would be the most accurate way to mesure it, might do mine to see if the +20mm is true Quote Link to comment Share on other sites More sharing options...
TheMunn Posted December 5, 2005 Report Share Posted December 5, 2005 With nearly all trials geo in the UK it would be if you draw a line from both axles, then its how many 'mm' over that, same for dd drop. In the states I think ( on some bmx's aswell ) they do it in inches from the floor. Quote Link to comment Share on other sites More sharing options...
Ashley Smith Posted December 5, 2005 Report Share Posted December 5, 2005 when the manufacturers measure from the floor that is measuring the bottom bracket clearnace the bb rise is measured from the imaginery centerline between the wheel axles to the center of the bb ash Quote Link to comment Share on other sites More sharing options...
