I would like to find out how people's LeVel hubs have been working for them. Saw some threads that are a few years old...how have they been holding up? I'm looking to build up a 135mm spaced wheel and was thinking of going with a Surly hub. However, the LeVel design just makes so much more sense. I understand the drawbacks of the proprietary cogs and am looking for feedback on their durability. Particularly from people who ride in bad conditions on urban pot holed roads and are generally abusive. Thanks!
