I am looking for some new wheelset and got to know of these Taiwanese Bitex hubs.
Searching on the web, there is Pro Wheel Builder from Atlanta area that carries this hubs. Not much other places from what I can find.
Reviews for the Bitex RAR12/RAF12 seems good - but I found there is also RAR13/RAF13 that is much more cheaper.

Does anyone have experience with these hubs?
Anyone know the difference between 12 and 13 - some cheap carbon wheelset from China has the 13 one on eBay.
