If, for example you were to take a Yeti 575 with a 150mm RS revelation and the resulting static head angle would be 68deg & the BB height be 13.3" (according to the Yeti website)
If you were to fit a Works Components head angle reducer head set thingy and slacken the HA by 1deg (the maximum according to WC), all things being equal i.e. the fork remains static / unsagged as does the rear shock how much lower would the BB be?
It's basically a maths question, but to work it out I'd need the A"C of the fork & the stack height of the lower head set cup, so I thought I'd ask on here
