Although I did state Ace said they now make the hangers straight, I did happen to check out a set of the new forest green ones. They have regular nylock nuts on the axles, but still had the ever so slightly curved “rocker” in the hanger. Just as much as a set of ones that came stock with the .38 specials. So it seems again, you have to take everything Ace claims with a grain of salt.
I’ve yet to have any problems with bending or axle slip, from their old design to the new ones. Curved hanger or not, they both work fine. They just need to focus on a stricter quality control, with hangers and axles coming out even. Especially making sure the axle facings aren’t all wavey, deformed looking, and oval-like. If you pay attention you’ll notice some sets look sloppy at the shop.
