Apparently all serious cyclists shave their legs.
Being one of 3 unrepentant cyclists at our club
races who havent bothered I would like to know why?

I was once asked [in Calistoga, California] whether I was a "serious
cyclist", after having ridden from Sacramento via the north shore of
Clear Lake around Soda Bay [some considerable distance]. I replied that
I am more of a light-hearted cyclist, to the dumbfounding consternation
of the questioner.

As for why those "serious cyclists" shave their legs, I have no idea. As
a bearded man since before many of them were born, I haven't figured out
why they shave their faces, much less their legs.
