I don't know about the older English built 5 speed hubs but my newer Asia built non-(W) isn't much to be proud of. I rode it two seasons with the factory lube, tolerating crappy shifting and 180* engagement slips. When I went to overhaul it it fell apart as I removed the guts from the shell. I ended up having to pull it apart to get it working, no index marks for the planetary gears means it's running rougher than it did new. Lube leaks into the drum cavity making the rear brakes very weak. I installed a Nexus 8R35 with roller brake in the meantime, now I am looking for a new rear hub. I'll think I'll wait for the SRAM products, maybe I should have my sanity checked after dropping $450 on the turd im9....
