this has come up a few times before, but i really don't think that that nashbar hub is a formula hub. anyone who owns one (or many) like i do will be able to see the difference.
it may be a decent quality hub, and probably better than a suzue basic, but i don't think it's a formula.
sidenote: if this is true about the price of formula hubs going down so sharply i feel bad for tony at IRO...he was the one to break ground with these things, and deserves the business.
