I believe belt drives are an excellent solution for bicycle drivetrains, and that they’ll continue to grow in popularity over the next few years. The advantages of belts are many, and the downsides few, the most obvious being the need for something other than a derailleur to change gear ratios. As internal gear hubs become more ubiquitous, I believe we’ll also see an increase in the number of bicycles spec’d with belts.
The Los Angeles Times published an article on belt drives yesterday. We’ve also written about belts, and we’ve reviewed two bicycles outfitted with belts that will be available for 2010.
