I like to change mine out every 7000 miles or so, i can tell when it starts feeling slopy back there to much lash in the drive train
Hmm, Mine started feeling a bit chopy a couple of weeks ago. When I shift gears sometimes it feels like something is wrong with the rear tire. Never thought about this..
+1 or was.... GaleSpeed wheels use a much different cush drive and have not had to replace them yet..every other rear tire change so abought 8000 mile.
SmithBoosta or something close to that had some heavy duty cush drive rubbers. It's really going to depend on the rider. Shake the rear wheel, you don't want a lot of play.
