I used to maintain a cadence in the 90's and would occasionally spin up to the 120s... my low was in the mid 80s. (This drove some therapists nuts once after knee surgery in the mid '80's... they insisted I should ride their stationary bike at 60RPM which was ridiculous)
This was checked with the old cateye cyclocomputers... these days I typically ride in the mid 80s, and I cannot seem to "spin up" at all anymore... in spite of better shoes, and better pedals.
I am on heart regulation drugs... and feel that may be part of it... but I am just wondering... do we lose that "spin edge" as we get older?
Has this happened to others out there?
