If I recall, on the old ones the hex was not consistently clocked relative to the bolt pattern, so it wasn't possible to use two of them on one wheel. Instead you'd need to use one plus a hex bearing held in place with screws. I'm hoping this is what is different and the new ones, so that two can be used on a wheel and the hex flats all line up. |
The new one is plastic so it's designed for lighter duty applications. At one point VEX started making all their Hex hubs aligned to the versakeys and I'm betting they still are, the plastic ones will definitely be aligned since they are molded. At one point they had to rotary broach some of their plain bore hubs to meet demand and those weren't aligned.
