I have a buddy who is an old roadie and still trains as though he was racing. That's cool and all. He likes the big rides and does them often. Years ago, I purchased a mirror, the one that attaches to the bow of your glasses. He was like, "those ain't cool man..." Needless to say I never wore it. Recently, I came across it and have done a few rides while wearing it. I like it. I ride on the road and can't believe how easy it is to glance back versus the constant headturn. I still am prone to firsthand looks (non-mirror image) when maneuvering right hand turn lanes and a few other crucial and potentially dangerous situations. I like the mirror. Am I not cool anymore? Anyone else (I've seen a few in the profile pictures) wear a mirror or maybe, gasp, have one mounted on their steed? Safety first, convenience second, coolness third.
