My
guess is that OP is using longer than 165mm cranks, which make carrying unloaded high RPMs difficult sometimes.
Also, in doing cadence ladder drills (10s x 100rpm, 110RPM, 120RPM, 130RPM, 140RPM, etc...), there can be some odd frequency issues at a certain point. At one point I noted that, using 170mm cranks, I could hold every cadence at will smoothly up to and over 220RPM...except 130RPM. It was this weird frequency that disrupted the flow.
I'm pretty sure it was just a perfect storm of me, bike size, crank length, tire pressure, tire bounce on the barrels, and legs bobbing up and down that was simply dissonant.
It's worth noting, this went away when I went to 165mm cranks.
I think everyone could have this odd dissonant RPM.
This could or could not be OP's issue.
