Nice bike but I have to ask, is that in your house?

Heh.
The teammate/friend that went to Belgium with me, he rode a 66 cm Cannondale. We were assembling the bikes and I had his seat post and his frame in my hands.
"Where's the mark for the height?"
"Just put it to the max height line."
"Oh."
With me on a 50 cm and the post so low I had to raise it to clamp my frame in a work stand we were quite a sight. Plus Cannondales were unheard of, I had Aerolite pedals, new Ergo levers, super light wheels, and we both totally sucked. We totally illegitimized US racing while we were there.

well, I don't know but I found this while googling. my legs are delicious dark meat!!
If you were to look at a muscle biopsy you’d see both red and white along with various shades of each. The white being pure fast twitch and the red being pure slow twitch. Think of eating chicken, the white meat (breast) is fast twitch. The dark meat (legs and thigh) is slow twitch. Chickens don't fly around very often yet when they do those muscles have to fire quicker, thus, their breast meat is fast twitch. Chickens walk around on their feet all day long thus their legs are slow twitch and better suited for endurance.

some bodies work very well for cycling and not at all for running, for example.

And movement is generated across joints, so I'm not sure how a long muscle pulling vs a short muscle pulling on the same size knee joint, e.g., changes much.

it's obviously a complex thing and there's more than one way to be a great cyclist--i'd just read some stuff in the past about femur length as a function of leg length and those with higher ratios tended to generate more power (for longer durations, not sprints).
but whatevs.

longer lever arms can mean more leverage, no?

I dunno. here's a somewhat educated opinion on a somewhat related topic. tl:dr longer bones = less leverage, but longer muscles are in the optimal contraction cycle to generate force for a wider range of contraction.

i dunno but does whatever you quoted translate from the loads in arm wrestling (more degrees of freedom but mostly lateral, i'd guess?) vs cycling (pretty limited to extension & contraction)?
the stuff i'd seen was cycling-focused.
i don't know the answer but would ask the above question before applying to cycling. cycling's a pretty limited case--i'd think less complex than arm wrestling.

squatting is probably a lot more like sprinting than longer threshold efforts.
not really important enough for me to discuss further. whatever i find probably won't convince you, so not gonna spend the time to look up some old reference i once saw. i could be wrong, anyway, so just assume that my memory is flawed. (seriously)
