DT Swiss hubs seems to get a lot or recommendations, but I don't understand why. They are absolute rubbish. The seals are made of Swiss cheese - full of large holes and the bearings are just standard cartridge bearings which have no place in bicycle hubs in anyway.
The rear hubs are particularly problematic. They use proprietary roller bearings and a very thin pawl spring that's prone to rust and then breaks, leaving you without a ratchet up a creek.
It even has its own chocolate factory. After a wet ride and some time to stew, you end up with emulsified, rusty grease like this. That little ring in there is the spring. Two rides like this and it has rusted through and broken.
Avoid like the plague. The only thing with DT Swiss stamped on it that's worth buying is a spoke. They make rubbish suspension and rubbish hubs.
