I'm with SciFi--I just don't GET it. I don't scoff at what anybody rides--I do about 25 percent of my miles on a singlespeed I made from an old touring Trek and a BMX freewheel. But I run out of patience in about a second and a half with anybody who won't learn to shift. This is a marketing gimmick by Shimano, and I hope it works--if there are more people riding, we'll all get better treatment in the long run. But I wonder if they'd be smarter to emphasize how easy it is to shift a modern bike, either internal hub or indexed w/derailleur, than to dumb down and heavy up the bikes.
