Of course, you could always convert to fixed gear, start waxing (chain, not legs) and move to the SW. I've got close to 11K miles on my Riv gofast fixie and there is just the barest hint of wear on the ring and none at all on the cogs (which I have admittedly changed from time to time but not "replaced". High torque, too, and a lot of dust. 3/32 drivetrain.
Phil bb and rear hub also as new, as is SunTour cartridge front hub, all with same mileage.
