There has been a lot of interest in belt drive on a winter cycling mailing list to which I belong, and one member has posted his results. The benefits are that a chainguard is not required, it never needs lubrication, and it is free from corrosion, and "chain stretch". The member reports that the efficiency seems comparable to that of a roller chain and that the pedaling action is smoother. However, he also reports that the belt can clog when used in snow and ice, although Gates (wo make the belts) claims to have a fix for this. I think that this may be a technology worth watching.

Trekmogul - how do you like it so far? How is it different from chain drive? It certainly is a good looking bike.
