Box Two Prime 9 Speed ShifterClassed as Box’s most durable shifter, this 9 speed model features a hard-wearing two-piece resin and steel lever construction, which makes it more than capable of handling all the intensity from exploring the MTB trails.The Box Two shifter is the only shifter on the market (other than our Box One) that comes factory stock with a hinged clamp. Box Two is our performance tier so this shifter still maintains the durable cast aluminium top shell but trades out the Box One’s 1-piece pull-lever for a 2-piece resin and steel variant. All Prime 9 shifters take advantage of the 9-speed’s inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won’t have to constantly adjust your set-up.FAQ:Does the Box Two Prime 9 Shifter come with a cable? Yes.
