Add me to the long list of sliders wearing to quickly. I know this is getting beat to death but I hope ski doo is keeping a eye on the site and can see there is a problem. I know its wearing out on hard packed trails were there is less lubrication but my wife on a 04600x right behind me is still on the first set with 2300 miles. And looking like new. 100% of my riding is on groomed trails so I'm going to have to do something here to fix this problem. Kinda hoping doo has some answers here soon.
