So, one should be aware of cadence because (on 'flat' terrain in 'reasonable' weather):

--------------------------------------------------------------------
'High' gear, 'High' effort, & arguably Low cadence(Less than 80rpm)= 'Bad'

-'Poor' improvement rate for the 'inexperienced' cycling enthusiast.
- Not 'ideal' for relatively longer distance rides.
- Eventual joint damage .
---------------------------------------------------------------------

Lower gear, 'Medium' effort, & 'High' cadence (>80rpm, <110rpm)= 'Awesome'

-'Optimal' improvement rate for the 'inexperienced' enthusiast.
-'Ideal' for 'long' distance riding.
- Bread and Butter for a considerable number of 'professional' cyclist.
--------------------------------------------------------------------

Am I right so far?
