Im thinking of going from a 2011 epic comp 29 to the 2014 camber 29 evo for xc trail riding. Question is will I miss the efficiency of the epic. Has anyone made such a switch or own both and can comment on the efficiency difference? I was never in love with the xc geometry of the epic and it becomes uncomfortable after about an hour of riding and this is with a riser bar and spec stem flipped to the steepest angle. Im looking more a more relaxed geometry like the camber.
