I'm rolling on ~4yr old Shimano LX hubs. The freehub body is wobbling and the nut assembly is tight so I'm thinking the body is failing. Any ideas on what is a good hub? I race sport/expert categories in NORBA/Collegiate so I am looking for quality stuff and preferably sealed cartridge bearings. I know DT Swiss makes some groovy hubs and Chris King makes some chi-chi stuff, but I don't know much else. Any of you other racers wanna give me a little input on good hubs? I know I'm gonna be looking at a pretty price to get my wheel rebuilt but its worth it!
