I'm confused. The description of the 2006 Reign 1 as above says Fox 36 forks, Sram drivetrain. The Giant website says the 2006 Reign 1 has Manitou NIXON forks and Shimano XT drivetrain.
So giants website is out of date... why does that not surprise me. Mind you still seems strange that the label is the same - 2006 Reign, you'd expect the spec to change as the year changes rather than midway through one.
