this makes no sense.
i don't see how this is possible unless you were lifting your leg purposefully.
because otherwise physics would dictate your foot rides the pedal up as it forces your leg upward because your other foot is forcing the other pedal downward.
and i doubt you were downstroking so hard that the upward force was launching your foot off the pedal.

The one thing that hasn't been discussed in the pedal retention debate is centrifugal force. I suspect that it is the reason why pedal retention becomes important at much higher cadences because the higher speed of the foot/leg mass results in a tendency for the foot to fly away from the pedal.

Yeah, yeah, yeah. It's a useful description to describe what is happening when the foot wants to move away from the centre of the rotating cranks.

says this:
Since the centrifugal force appears so real, it is often very useful to use as if it were real.

Yes, but only if you use SPD style pedals/shoes. If I try to kick anything with my road shoes/Look cleats, my other food tends to slip out from under me and I fall down. Thus: platform and spd pedals make you more efficient ass-kickers.

Our Wednesday breakfast ride at work featured a discussion on clipless today. None of us are racers, and only one guy goes with clips. The conversation lasted about three minutes, advice was shared on SPD/Crank Bros/Clips, then we rode to work.
It reminds me that this thread started as a molehill and it has become a mountain.
