I feel like the new 2015 Giant Reign isn't as good as their older 2013 models, the bike geometry feels like it puts you in too much of a attack positing over the center of the bike even when riding on flat trails which isn't my type of riding style. The bike feels quite heavy and very pedally even when its not climbing, does not keep momentum going for a long time even though it's a 27.5 wheel size. The 2015 Focus sam is very good bike on climb compared to the Reign due to it's geometry, i rode one with 2.4DH tyres and it climbs like effortlessly even with those big fat tyres and the bike also feels lot lighter than the reign and both are aluminum. I wouldnt recommend this years Giant Reign to be honest.
