I own a couple of sets of Tune hubs now and they need a bit of love occasionally, they start to creak when they get some dirt inside... the downside of having lightweight hubs, seals might weigh something and are not needed.
Most of my wheels have the good old reliable Hopes, I have seriously never had to service or replace any item on a set of Hopes.. ever... and I have owned and own dozens of sets. I reckon I have about 8 sets of Hopes on bikes at the moment, my kids ride competitively and we have 18 bikes in the garage/vault.
I have given a mate a Hope freehub that he killed by riding single speed and hes a big bloke, but thats it, the only failure I have ever been a part of. Bang for buck, there is not a better hub out there, and I have owned a few "great" hubs over the years, 240's, I9's, Kings, Tune ect..
