Had a track specific fit done this weekend. It was interesting.
They lowered and moved back my saddle. (Those two usually go together to keep BB-saddle distance the same, but the change was enough to increase the bend of my knee at the bottom of my pedal stroke.)
It turns out my 170 crank arms are perfectly fine for me. (I am on 170s because I got a good deal on a used SRM, and I would have swapped to a shorter length if needed.)
We also lowered my bars about 1.5 cm. By objective measures, my bars should be moved about 1 cm closer, but I just felt too cramped, and I apparently looked it too.
I'll see how I adapt to it over the coming weeks/months.
