I believe that the only thing that distinguishes SR hubs from Record is the titanium axles -- I've never seen any, but expect that they'd be a gray color rather than blackened steel. Hub shells are exactly the same as Record AFAIK. Meaning, when they're on the bike, with axles completely non-visible, nobody can tell that you spent the extra money, nor that they might break under you! They weren't very popular, because of this. Unless you're on the 160# side of things, you might consider an "upgrade" to steel.
