Is there a calculator that will give me the stack adjustment for various stem angles and lengths? For example, if I ride -6 degree, 120mm stem with a 73.5 degree HT angle, how much stack is that adding? Basically looking at how many spacers (or different stem angle) I would have to use for various frames in order to achieve my optimal fit.
Thanks
Get your trigonometry books out! 
or you could use the one here!
Right under my nose! What a resource ST is. Thanks.
Dan that’s awesome. It would be double awesome with a scan of a simple hand sketch of a stem, illustrating what all the input and output dimensions refer to.
good idea. we actually have a couple of versions of that. the other one’s here, and it gets from you HX/HY to stack/reach. that probably needs a sketch as well.
was always a big fan of this one:
My favorite, as it draws nice graphics so you don’t have to hurt your head as much to visualize the change:
