the dt swiss is good for nomale xc riding but when u start to taking it FR and stuff u need a stiffer rim that doe give way go for the mavic crossmax sx 2008 that is the same weight as dt swiss but then u use tuless or go for the 2009 crossmax sx,

 yeah, those hoops arn't the strongest. I had 719 mavic laced to hadely hubs on my pitch.

 i had to replace my front rim after a bad landing ):
