Brecoflex Treads

Clicking on the images you sent shows that only the Linatex Red and PVC White are 1.1 CoF. The rest are lower than that. I thought that Blue Nitrile from McMaster was either 1.1 or 1.2, but I don't have that right now. Maybe someone else can chime in on that.

Rather than grinding off the teeth, perhaps you could use the stock pulleys or bar stock to make your own wheels to the exact size you want. Then rivet the belting to your homemade wheel. Or you could just cut to size and rivet to the AM wheels.
