I think innovation is cycling is great and should be welcomed.

Honestly the chain is great. It's cheap, durable, efficient and easily serviced. Sure it can be greasy, noisy and can break (what doesn't), but it's though to beat.

Belt drive sounds great I'd like to try it. A few drawbacks I heard is that apparently the tension is much higher than for a regular chain and has to be set precisely, as the alignment. That might not be harder to adjust than correctly push a chain rivet however. Furthermore I'd like to know how you can install the belt!! (without cutting through the frame).
