Have not gathered the Data.. only put a computer on for the 2 odometer functions on bike tours.
my computer on that bike is down on the fork-blade.. rarely look at it.
I stay just ahead of the chosen gear-ratio.. so Im not mashing too big a gear,
or trying to keep up with one too small..
when I'm on my Brompton, 3 speed, I adjust the speed to the gear, low too fast a cadence ?, Slow the pace.
