Their road hubs are very good. I have a pair Full Carbon Clinchers, Full Carbon Tubulars & a pair of 50mm Carbon /Alloy rims with these hubs. Fully sealed japanese bearings that seem to roll even better after a few rides.
Cannot fault them as yet & have found them better than a pair of ZIPP's I had previously. Proof is in the riding.

Yes, being a Taiwan manufaturer they do OEM work for many brands of wheels. Who really knows how what hubs are made for who anyway. CNC machinery is CNC machinery no matter which country it comes from. Only thing is these days the Taiwanese the lastest & best machinery going around.

Its no different with bike frames too, many famous brands coming out of the once laughed at Giant Taiwan. It only recently that some have fessed up to it but still some too snobby to admit where their frames are made.
