Doing some research on wheel parts to build a set out of. I've gotten some recommendations and ideas from here in BF, but would like to know a bit more about what the advantages/negatives there are between the two. Cartridge bearing hubs I've seen are lighter weight, and I assume will have a "replacement" interval. Cupe and Cone hubs (i.e. Ultegra hubs) tend to be heavier (partly due to the steel cassette body) but are very much a tried and true hub design, and will likely involve a "service" interval.
I know that the cup and cone style can be easily 'snugged' down to proper tension as well as re-greased. Sealed cartridge bearings can't be regreased, and I assume cannot be 're-tentioned' if they ever develop adverse movement.
How much of a concern are these issues? I apologize if this has been fully discussed before, and if you know of a truly thorough explanation in another thread or website, please link me to it. I appreciate your help. The build that I'm wanting to do is going to be a somewhat budget build, so paying $200+ for a good rear hub isn't really an option for me. I know wheel builders such as neuvation have been able to produce trusted wheels on imported cartridge bearing hubs, but if I want to build my own, the opportunity for good reviews on these cheaper hubs isn't as convenient.
