comment How can I avoid getting chain grease on my trouser leg
hi batman: the guys from carbon drive systems claim to have solved most of the problems related to typical belt drives. they use carbon fibers to strengthen the belt to prevent stretching. this reduces the need of high tension, which had been killing the bearings. so some of the drawbacks are gone. But I speak theoretically, as I do not own a bike with belt drive yet. But I think it's a very interesting alternative for a city bike.
