Okay, cadence, got it, ORIGIN late Middle English (in the sense [rhythm or metrical beat] Got that angel number from a road worker, maybe he was mistaken, I often get information from the wrong sorces, BUT NOT THE BIKE FORUM lol. So, I have had good/better luck with biking and less knee pain and have watched my knees, lowered my seat, been concious of the beginners mistake, although I been doing this for 4 years I am still a beginner, we all are at some point and this is digressing.
Thanks for the help, closed and wish you all no wind, flat paths, no dog walkers and good cadence.
