Been there too:(
The folders do break off much too easily, IMO kinda missing the point. I had the T-rex rear axle sliders hit the pavement and unload the rear tire before the factory pegs touched .
IMO, the multiple holes in the rearsets are just a fashion statement. It doesn't fit any peg I've ever tried in anything but that one hole.
My feet are much too wide for the fancy shmancy $400 ones EBR sells (anyone want them? Lol, I haven't heard back).
