I'm in the process of considering whether to start deciding if I should buy a new Co-Motion. (Which means I'm definitely getting one, the question is when ) I want a Periscope, so that my stoker can have the option to be captain, and either of us can ride with a stokid selected from stoker's extensive collection of grandchildren and other small relatives. The question I have is, should I get the Gates belt-drive sync "chain". I like the idea of it, because it's all high-tech and stuff, but I've never even seen a belt-drive bike before, and it its an extra several hundred bucks. I don't care about the few ounces of weight saving, but if it really does work better than a chain, with less maintenance, that seems like a big plus. So, does anyone have one? If so, how is it?
