It's been a long time since I've been in the market for a new bike. I'm seeing some nice road bikes with 2 chain rings instead of the 3 chain rings I'm used to. I can see where this would be an unremarkable difference if you ride on primarily flat terrain but if you live in a moutainous region I would think there would be an advantage to having more gear choices. I am not a high performance rider, looking mainly to get from point A to point B with as much fun and perhaps a couple of donuts along the way. I was wondering what others think of this trend and what their thoughts are of 20 speed bikes.
