THIS CHANGES EVERYTHING
What is Gordon Wadsworth’s setup? Just do that and you’ll be fineI see. Makes more sense. But if the bikes completely different geometry And different travel forks, then it's tough.

I think Santa man is saying to measure it the same measurements as the pivot, bar drop/height blah blah
If the Pivot is comfy, then mathematically it should be the same
Well, when you add a spaced tour stem comes up and back changing reach. 7 degree 90mm.
Really? Thinking technically with a riser bar hand position goes straight up. With moving a spacer under bars go up and back.Changing a spacer is exactly the same as swapping to a riser. Your body will be in the same spot and have the same effect on handling.
He gets it!Spacers move the stem up and down along the HTA, whereas a taller bar is independent of the HTA.
He gets it!
Doesn’t the stem technically move rearwards slightly as it climbs of the steer tube? Not a huge measurement but any small adjustments in the area are noticeable.But your body position ends up in the same spot, which is what effects the handling. I have an XY tool at the shop if you want to see how exactly the same it is.

I’ll try to stop in with both bikes soon.You'd have to raise it a lot for that to come out in a measurement. But yes, if you had a foot of steerer it would. Seriously, we can do this all with a tool and you'll know exactly what you need to do.
My bad, was actually a 12mm spacer. But still, moving stem back 4mm or more changes bar over axle position.If i did a quick calculation - a 20mm spacer with a 67deg headtube angle will move the bars towards the seat 7.8mm.
sin(90)=1
x=20 x sin(23) = 7.8
the rise is 18

IDK, I am not going to try and math it out like @Patrick but it always felt better on the mtb the closer you can get to being slammed with the stem and run a riser bar. Especially for things like cornering. Mind you we are ignoring sweep and rise that riser bars typically have compared to the average flat bar.Changing a spacer is exactly the same as swapping to a riser. Your body will be in the same spot and have the same effect on handling.

Briefly reviews Pat's EVO setupSo i'm rethinking "actual" vs "effective" -
reducing strain on your lower back (or reducing weight on the bars) means being more upright -
assuming your bars are below the pivot point of your body (there is not 1 pivot point)
moving straight up would decrease reach and bend angle, if it is above, it actually increases reach, but offset by reduction in angle. interesting.
it also messes with effective stem length (if that is a thing? virtual center of bars to center of steerer?)
so much for academic look - it probably isn't worth a dime until you try it out, and see what works. like those compliant bars that give a little
in the vertical.
