To simply answer this question....yes there is. It would only be worth it if it lasts longer than 2 standard HTD 570-5M belts. And that can be a pretty big if, if a pebble gets between the belt and cog. They just snap!Heres something to consider. Grainger has a Goodyear Polyurethane belt 115 teeth, 16mm wide 5mm pitch for $27. This would probably never wear out! Is there enough margin to handle the xtra tooth and width?
