Ever since the first, totally rundown and old bicycles of American newspaper boys were modified for mountains, gravel and forests, mountain biking has been about defying tradition and improving driving. And every new driving style needs a perfect solution. EX1 is the world's first propulsion system designed to meet the unique needs of e-mountain bikes. With the proven SRAM 1x ™ technology as its DNA, the EX1 cassette is the heart of this group. It allows optimal gear shifts for more targeted gear shifts and the best gear ratio for mid-range e-MTBs. Each EX1 component was designed to be the perfect complement to the system. The result is smoother running, intuitive switching, longer battery life and more resilience. EX1 opens the door to a beautiful new world of mountain biking.
