I'm also concerned about not having rotating flanges on at least the center pulley. My old team used the Vex belt upgrade on the AM14U chassis in 2014. It worked for the season, but the belts showed some pretty hairy wear, as the sides of the two belts rubbed past each other on the common, center pulley.
