Once again I get to a poll and it's already closed . . . I just don't click on 'em soon enough.
Anyway, my answer would have been 21+. Hey, I've been cycling since '68 and I never (okay, rarely) throw one out . . . never put one on ebay.
Plus (big PLUS) my ex just sold 'our' old house and in cleaning up she found four of my old wool (yeah, real wool, like grows on sheep) jerseys and sent them to me. Now I'm toasty warm on winter rides! Everyone calls them "retro" but I just call them warm!
