Solid read and insightful. Thank you.
One thing that I've been having trouble with is upstroke to assist with the opposite downstroke of the crank turning. I've noticed that unless my straps are tight on my foot, limiting movement, I'm losing efficiency and have wondered if going clipless would help with that.
Anybody notice improvement in hill climbing when switching from clips/straps to a clipless setup?
Absolutely. Climbing is significantly more efficient on a clipless setup than on clips/straps.
