For today's commute I wore one of the cycling jerseys that I reserve for weekend recreational riding. I felt kinda silly the whole way in. I want to send a message that you don't have to go out and buy a whole new wardrobe in order to bike to work... That, and for some reason I always feel overheated after riding wearing one of the jerseys.
Warren, this is essentially the position that Grant Peterson takes, and it makes a lot of sense. It's not just about riding a bike to work--I should be able to go on a club ride in a pair of normal shorts, a t-shirt, and a pair of trainers without feeling like the odd man out, surrounded by lycra. Specialized clothes are OK, if you really need them, but they are just another obstacle for getting someone to ride a bike regularly.
Then why do you guys wear it. I have a couple jerseys and a couple pairs of shorts but I only wear them when I have to, not because I'm embarrassed but because there's no reason on rides under 20-30 miles. Show up at your club ride in an ACDC shirt and cut-offs. If they don't let you ride pull a Jerry MacGuire and see who's coming with you. Start your own ride.
It's a comma splice anyway. I get treated better in street clothes, far as I can tell. I wear whatever's on the top of the clean laundry clump. Why should you make the people who want to wear lycra dress like you, though? They should change clothes, lest you feel "like the odd man out"? Must be a man thing. Good thing women aren't so obsessed with what people are wearing ;) ;) ;)
