Sram x01 11 speed trigger shiftertheres not much to report on the new sram x01 shifter all the pertinent technologies carry over from xx1 the x01 trigger uses the same cable pull and has the same zero loss design allowing you to fire off successive shifts with ease the x01 shifters are also matchmaker x compatible the primary difference is that the xx1 shifter has a carbon cover while the x01 version uses an aluminum shield that allows access to the shift cable and other internals claimed
