Does anyone remember, 20 years ago or so, the Ladies Mountain Biking and Tea Society? One of the first bunches of women to really get out and ride with the men, and they always wore pearls and lace gloves and "girly" stuff so the guys knew they were being passed by women.
Folks who make rude comments about your pink bike (and hoping you'll hear it) are insecure and trying to make themselves feel better by putting you down.
I'm not a pink bike kind of gal, but I have a pink helmet and lavender bar tape and usually ride in a skort.
Ride on!
