It sounds like you have an issue with the hex-wheel fitment. The JConcepts hex fits on the AE axles, also the JConcepts axle. The AE wheel fits the JC hex. The AE hex fits the JConcepts wheel. The issue is not the axle.
I never once said there was an axle problem!!!!! I simply stated that other's have had problems with Avid Hexes on the JC axles and with other wheel besides AE or JC. It would be nice if JC could point this out. A simple asterisk on the site/product page and in the product description would work. Not too tough and hell, it might even sell some more blue hexes for JC
