DieselnDust Posted May 25, 2020 Share Good old pythagorus. If your head angle is 70 degrees then a 20mm rise in spacers will give you a 17.3mm vertical height increase and 10mm back. Edit: I hope - it has been some years since I used sin, cos and tan :-) 18.8mm up (sin70x20)6.8mm back (cos70x20) can't use pythagoras because you only have one measurement that is known.
