Recently, I've had several customers show interest in having me build up wheel-sets using the American Classic hubs. I am giving my professional opinion of the hubs. I cannot say that I recommend these rear hubs for anything other than race-day use if you are a heavier rider or are rough on wheels. The reason I say this is the method of which the rear hub pawls engage the free-hub body. These hubs are reverse from pretty much every free-hub in existence in that the pawls are mounted inside the hub and the gripping teeth are on the free-hub body itself. The problem is that the teeth of the free-hub body are aluminum being gripped by the hardened steel pawls. This steel vs. aluminum causes rapid wear of the free-hub body teeth, causing engagement issues. Below is an example of a new free-hub body and a free-hub body that was used for one season by a rider that weighed 190 lbs. In the top picture, the new free-hub body is on the top with the used one below.
