re: going public, I carry a few sheets of paper towel & a vented baseball style cap. so I can remove the helmet, wipe down & cover my hair. when I used to ride in tight cycling shorts I also brought a small pair of running shorts to whip on as well. now I ride in MTB shorts over cycling tri-shorts but if I expect to go into a business w non-cyclers, I still bring the paper towels & cap. never know when you're gonna meet a pretty lady, right?
