It makes good use of nylon composites in both top and bottom shells as well as the levers. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. Prime 9 is also terribly forgiving so you won't have to constantly adjust your set up. Multi shift lever allows you to pull several gears at once (up to 3 per shift)
