I had a set of Chrinas on Tiagra hubs, from SPA. Didn't take long before the eyelets started to rip out of the rim and eventually the rear hub fractured on the NDS flange and 2 spokes immediately lost tension - rim 'banana-fied', meh. I have built my own wheels last summer (Chrina on 105 hubs), so far they are ok, aside from one spoke breaking on the rear and it needing to be completely re-tensioned. I have had to tweak it a cpl of times but we'll see if the rims hold up better than the first set!!
