The reason that there is no market for belt drives is because most people have recognized that it's just another expensive gimmick with no real advantages...I have seven Canadian winters behind me and I find chains to be very reliable, easy to maintain and cheap to replace. Why change something that works very well ??.. And even if my chain did break , then all I need to do is get my chain tool out and fix it with a spare chain link which I always carry with me.
