Below is the reason you won't be seeing the Reign anymore
Meet the 2014 Giant Reign (not really):
2014 GIANT TRANCE 27.5/650B
The Advanced 1 has more travel (140-150mm), Fox Racing front and rear and Shimano XT drive train.
The showstopper of the 2014 Giant Trance models has the most travel with Fox Racing Shox front and rear as well as the new SRAM XO1 drive train.
