I think this chap has an interesting take on bike fit.

The bike rotates around the BB so what is important for dynamic bike fit is the distance from bars to BB. It is a very different take than stack/reach but focuses on getting the bike setup to make it optimal for hinge positions and rowing/pushing the bars.

The Pace geo chart is with a 140mm fork, unsagged, offset bushing in the high position, 29” wheels.
I’m running it with the offset bushing in the lower position, with a 150mm fork, and a 27.5” rear wheel.
I think that this means I have probably shortened up the reach quite a bit- and I’m wondering whether it was that, plus the slightly lower BB that contributed to the “ah, this turns in much better!” feeling that I had the first time I rode it as a mullet.
Does this make sense?
I’m worried that comparing a geo chart of the Pace that is probably not very accurate to the accurate geo chart of the Madonna is leading me to make the wrong decision on frame size.
