As I've mentioned previously (complained, whined, etc.), I've had quite a bit of trouble with RSI over the last couple years. I've had to give up some of the sports I like (or would have liked to try someday) because the weight-bearing stuff makes my hands sore, sometimes for a couple days after. The times I've gotten on my old mountain bike, I've regretted it later. Since I live a mile away from a really great, 20-odd mile trail, it's been kind of a bummer.
Today, however, I was out rollerblading and noticed someone on a road bike who had his weight on his forearms, and then the bike actually had handles out in front of the usual handle bars (the brakes may have been up there, too). So, he was holding on with his hands, but not putting any weight on them.
This weekend, I'm going to hit the bike shop and see if this is some kind of custom modification or if it is a new option that some bikes are offering. I'll let you folks know what I find out.
