Todd, calm down u dick, There is no point in going off at him like that, just notify him politly that there is a search function on this forum and that this topic has come up before...
Anyway, Justin.L, I use the koxx rim on the rear and I love it, I will not use any other rim, I have the new 47mm wide one sitting in my room ready to be laced, even if I did get it for free.
I would not go near the front version of this rim however, I have just totalled the one that came on my koxx, they are crap, now I need a 32 hole hub and a new rim, because they gave me a 28 hole when I bought the bike.
Anyway, if u are in the market for a new rear rim, give the koxx a shot, if its built well it will last, hope this helped.
