Dave, this has been my go-to move since using the Retul fit bike. I'm specifically looking for muscle loading and rider feedback on the changes. You *have* to go slow, as that's the rate that muscles fire and reload. I'm sure a much more rigorous scientific approach could quantify it better, but when I'm done people feel very strong and efficient.
Interesting phenomenon I 'might' have noticed while using a Retul fit bike, adjusting drop, and asking for rider feedback. If I make about 6 full turns of the handle leisurely (about 1.5cm change), over a few seconds time, compared to making those turns super fast, say in less than half a second, the rider seems better able to perceive differences with the faster adjustments.
Has anyone else experienced this? Having done many hundreds of fits, I never picked up on this until just this past week, so certainly an N= "just a few" at this point. The difference in one particular clients' ability to discern differences was fairly profound. A couple others seemed to be helped by the lightning fast changes. And I mean I turn that handle so fast it almost drops them down at the speed of free fall.
I consider it limiting the "time between trials" in an extreme sense. Thoughts?
