Here on the 50+ threads most of the posts are pretty civil. Maybe it is because that us mature and older riders are not always trying to prove something. We ride what what we want to ride, not the latest $5000 unobtainium bike of the hour, unless that is what we want to ride. We ride where, and at what speed feels right to us. And that includes what pedal cadence feels right.
I guess what Im trying to say is that most of us are not trying to prove anything, and there are some things about getting older is really a good thing.
PS If you try to suck in your gut when some pretty young thing walks by you are not quite there yet!!!!
