I posted my experience regarding large folk in spandex on bicycles about a month back.
(never again will I ever presume clydes and athena's can't haul arse)
I've got several 30something neighbors (I'm 68 218lbs)who used to snicker about the large old guy on the bicycle.
Then one day..they tried to keep pace with the large old guy on the bicycle....and got dropped.
End of snickering.
Here's the way I look at it.
You're out on the bike doing something positive for yourself and your health.
Exactly what are those 'spectators in life' doing ?
