I dunno nuthin' Aica, you know way more than I do. For me, it just started last year when one of my riding buddies commented that I was flexing my ankles too much, then two weeks later I went for a fitting, and the fitter (a pretty experienced fitter and tri coach) said the same thing. My massage therapist noted how my calves were masses of trigger points and adhesions and suggested I stop toeing off in all my sports (I'm definitely working toward a midfoot strike running, and honestly kind of dreading going back to teaching aerobics where toeing off is unavoidable). In the past year I've read over and over how the current practice is to drive through the heels.

I do start getting pretty bouncy around 110 rpm, but the truth is I haven't worked on my cadence in over a decade. I used to be pretty smooth, but I used to work at it too.

So that's all I know.
