    1x11 may be the one the best game changers to come around this decade but there has been a common request. "We want lower gears." The smallest front ring for XX1 is 28 tooth and the for X0 and X1, it is only 30 tooth. 30t may work for most but folks with bigger wheels, heavier bikes, steeper...
