I know we have already posted up a singletrackworld.com link to their in-depth SRAM XX group-set release coverage but at the moment they are the only ones who are posting anything noteworthy. The launch is over and Singletrack now have the full lowdown in various stories up on their site. It's well worth checking out. Check out these US prices though, this isn't gonna be cheap.
Rear derailleur - $265, Front derailleur low clamp - $119, Trigger shifter set - $276, Cassette - $328, GXP Crankset - $430, GXP BB - $195, Avid XX brakes 160mm - $373
That's a total of US$1986 not including XX forks!!!
