I was making some videos of my clutch hand (for a future video) and I noticed that I rest my thumb on top of the bar. I never noticed that I do this before but I find that it is more comfortable to position my hand this way. My thumb automatically goes there when I am cruising at an easy pace, but I am taking corners hard I have a full grip on the bars.
Is there any reason not to do this?
Does anyone else do this?
