Riding posture?

Well it's very noticeable that pictures of racing bikes in brochures 20 years ago show the bars about level with the saddle. Now you'd have to search for a while before finding a picture in an advert showing this; the bars are now always several inches below the saddle. I keep a pretty relaxed posture on my road bike and only get down on the drops for a burst. My road-ised mountain bike is a bit more upright but still not sit-up-and-beg. Depends whether you want to be able to see what's going on. In my view really down on the bars is only safe if everyone is going the same way as you.

You'd be surprised at the speed of evolution for the cyclists body. Much more flexible in just one generation :-)
