Before buying any cartridge hubs, it'd be a good idea to know that a local LBS can service them. A few years ago I bought a set of wheels with SpeedCific hubs. I think that they are rebranded Formulas. At that time the wheelbuilder, Mike Garcia of Odds and Endos, recommended annual service. The OP used them in a road race during a heavy rain, which caused the front hub to need new bearings. I found one LBS who would try to service the hub. The rear hub was more complicated. Noone seemed to know anything about how to service them. The situation may have changed, but I'd want to know who would service my hubs.

BTW the OP said that when he raced the hubs, he didn't know that putting petroleum jelly on the sides would have blocked the water from getting into the hub. I'd still want to know who will service my hubs.
