.. [some] humans are cycling successively in the 5th generation now .. if these had 10kg shoes on when walking maybe the upstroke would have been influenced positively for cycling .. sorry, there is absolutely no study about heavy shoe walking correlated to upstroke while pedaling ..

edit: just some off season thoughts

LOL. I once owned a set of Frank's device.

Regarding the fore/aft pic and position.


What is the basis for this 2-4cm scooch forward? What is the advantage to having the knee be straight over the spindle at 90? (when viewed from drive side)

The further aft position seems to recruit more hamstring to the the contraction and one can still achieve a 90 down stroke if they rotate their POV of where maximal force happens.





Nice to see that I'm not the only one that thinks/fits this way!! #fullgas!

The further aft position seems to recruit more hamstring to the the contraction..

It seems to me, and all the cyclists friends of mine that venture into a more forward TT position, that the further you go forward, the more the hamstrings are recruited, so I think the opposite of what you are saying here? Whenever they do a TT off of a more slack position, they always come away with screaming hamstrings. I do too in the early riding of each season, but it gets trained, so goes away. I would think the more "aft" you get, the more your quads and other pushing muscles get engaged.


Or maybe that is not what you meant at all, but good discussion all the way around here. I too like to fit people to their go positions, unless they are never going to go of course... (-;

I did too. They convinced me that trying to apply power by pulling up is nonsense.

There’s not much evidence that any power comes from the upstroke.

Not how I see it. The farther forward you sit the more the quads need to be activated to keep the hamstring and glute contraction from forcing you off the front of the saddle.
