Box One Prime 9 Shifter

Box One Shifter Closeup

The Box One multi shifter is the only shifter on the market that comes factory stock with a hinged (and machined) clamp. It's top of the line and comes packed with other features such as a durable cast aluminum pull lever and top shell. 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. Available as a multi-shift (pull several gears at once) or  single-shift shifter (a sound choice for e-bikes).
