American Classic hubs are pretty much garbage and I wouldn't recommend them to anyone. American Classic hubs possibly get the award for most poorly designed freehub body on the market as well as having poor customer service and bearings that need to be replaced after a few weeks. The flanges on the American Classic hubs are ridiculously narrow and build a very flexy wheel as well. Some of the bearing and freehub issues supposedly have been worked out on the newer hubs, but they still are not in the same league as most name brand hubs. American Classic hubs are cheap and light, but not strong becuase you can't have all three.
The Ritchey is just an Alex hub, not bad but not that great. Shimano Dura-Ace hubs are impossible to beat for bang for your buck performance though they can be hard to track down in a 24 hole drilling. White Industries are also superb hubs readily available in all drillings and not ridiculously expensive.
