I recently changed over to a 2.8 pully w/no idler. I got lots of belt dust with the nonslip and gatorback 73.5 belt. well it started to fray on the edges and today when I got home the f#*ker was split right down the middle. What the hell is this from? I just 2 minutes ago ordered a 100mm idler and am getting a new GATES belt, proly a 74.
