Box Three Prime 9 Speed Shifter

This 9 speed shifter makes good use of nylon composites in both top and bottom shells as well as in the lever. Box Three is Box’s performance and value tier, so this shifter sheds all the fancy trappings of the top 2 tiers but still maintains their incredible shifting characteristics.

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.
