cyclists are rarely "snobbish"...but there are several very distinct groups of riders.
at the top of the heap you find 'the racer'. dedicated to his craft, he is trained to the very razor's edge. his fitness is paramount and finishing positions mean more to him than equipment or clothing. he is confident and has the reactions of a cat. graceful on the bike and brave in the pack at speed.
beneath 'the racer' (also known as a road warrior) are the 'tr-dweebs'. these guys live to train. their bike handling skills are often lacking, and their fitness level can get them into serious trouble in massed start cycling events.
next, you have 'the tourons'. these are the touring types. often seen carrying 20 lbs. of gear on a twenty mile ride. though lacking in speed and skill, their fitness often approaches racing calibre.
'freds' may be either 'tourons' or techno-dweebs'. i won't get into their characteristics...but, DON'T BE A FRED!
to be a cyclist, you MUST be able to say, "fuck the world"...and truely mean it when you say it.
i wear proper cycling gear and could give a flying fuck what some fatass in his car thinks of the way i look.
every piece of cycling clothing is designed and purpose built for comfort and speed.
if you are concerned about what others think of your looks and abilities, cycling may not be for you.
it is, and always has been, a sport for independant thinkers and those prepared to go their own course.
as stated above, shaving one's legs is the norm in racing. if doing that...or wearing lycra is somehow a challenge to your "manhood", take up another sport.
