Anyone else have a mirror on their road bike? I've used one for years, but I hardly ever see others with them. I realise they might not be the coolest accessory you can buy, ranking somewhere alongside the wicker basket or the child seat (I actually saw a rather nice Specialized road bike with one of these on the back a while ago) but the way a mirror enhances your awareness of what's around you more than makes up for that. They're most useful on quiet country roads, where you will generally hear a car approach from behind, but not the two or three immediately behind the first one, because the noise of the engines seem to blend together and mask each other. Also good for lane changes in busy town centres.
