High cadence issues related to being a clyde
So the other day someone on this forum pointed out to me that my 70rpm cadence was actually low, despite me thinking it was high. I went out and purchased a cadence monitor so I could get feedback in real time about my cadence (I originally calculated it by calculating tire size + gear ratio at my cruising speed... not something you can crunch in your head in real-time, heh).
Anyway, so today I took a 25 mile ride and during the ride I made a concentrated effort to stay above 70rpm. I could handle 75 with no problem, just have to keep in a lower gear, but when I reached 80, that's when problems started happening.
Basically, I felt sloppy. As a heavy guy, my legs are very massive compared to other people, so around 80 I felt the momentum of my legs lifting my whole body out of the seat on every pedal stroke, threatening my balance. In addition to that, (and not to be too graphic here, but I think it's something many of us here know about) there's actually still quite a bit of fat on my thighs so during each stroke I could feel it whipping up and down rapidly, and it was a pretty uncomfortable feeling.
Has anyone dealt with these issues before? Should I lay off the high cadence stuff until I slim down some more, or should I keep at it? Other posters seemed to imply that shooting for 110 cadence is a good goal, but honestly I am not sure that's such a great idea... Any ideas?
