The problem? Tekno's wheel hexes are not wide enough and/or the Pro-Line wheels have too much material; making the wheel's socket too deep. When I go to tighten the wheel nuts, the extra plastic that is .41~.70mm above the wheel hex (in picture) rubs on the hubs. So annoying.
Get the +1mm hexes, I had to for the same reason (though people kept saying it was the wrong offset).
