I thought about buying some of those myself, but decided not to when posters here on BikeForums claimed:

1. The bearings were probably junk at that price

2. The bearings & freehub could probably never be maintenanced or replaced

3. The alloy wheels would be prone to cracking over time

4. When the cast metal fails, it will do so catastrophically, causing a possible wreck

I don't know if any of the above claims are valid or just yahoos blowing smoke. Please keep us up-to-date over time as to the performance of your wheels - I'd like to know. Thanks!
