I wouldn't call myself a bicycle enthusiast, but I do enjoy biking as my third most common mode of transportation (Car, running, biking), and living in a big city it affords me a quite a bit more flexibility than my car. One of the huge drawbacks to biking is the problem of clothing...especially clothing getting greased up, stuck, or torn by the chain. I usually roll my pant leg and I've seen other people rubber band their pants around their ankles which is all well and good, but I didn't realize that there was another way out there until (while bored at work) wikipedia introduced me to the chainless bike. Powered by a drive shaft if offers higher clearance and comparable "efficiency" to chain bikes. Apparently there is a niche market for them over in Europe. I was wondering if anyone had used one and if so, how might it compare to my 27 speed Raleigh M800 mountain bike with street slicks and clips? Anyone?
