I've got a X5 2004 and i am currently running pikes and fox float on 6" rockers. The bike has quite a high BB (around 14"+). I know the angles changed from 70 deg in 2004 to 68.6deg from 2005 onward so i have not got a clue what my HA is.
I have also read a couple of notes that say that each 20mm in fork (axle to crown length) is about 1 deg but elswhere i have seen 25mm = 1 deg.
Does anybody have the definitive rule for each mm change in AC length vs HA change?
I can have a gues at my HA but i am unsure what the change in rockers ie from 5" to 6" has done to the BB height and if this has affected the HA of the bike.
just as a starter the 2004 angles are based on a AC of 478mm
the 2005 onward 505mm and the pike is a 518mm (at 140mm)
cheers for any help in advance
