The Box Three shifter makes good use of nylon composites in both top and bottom shells as well as the levers. Box Three is our performance and value tier. So this shifter sheds all the fancy trappings of the top 2 tiers but maintains their 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. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes).

    No, traditional 9 speed systems use a Cable Pull that is not compatible with Prime 9.

    Not good for XC riding or racing

    I have been using the Box Three shifter for 5 months after having purchased it in the early part of 2021. After the first 3 months, the shift lever started coming apart from the main casing. I have pulled it apart for a re-greasing twice and have made sure to tighten the lever fixing screw each time. I recommend re-greasing it after hard or frequent use. As a cross county rider who races and shifts under load a lot, I cannot recommend this for hard XC riding or racing unless you are riding less aggressively. I would recommend this for trail/enduro riders. The gear range you get with Box is very good. I also have a review for a Box One derailleur.



    its a little bit hard to press due to solid RD but its accurate and precise on my multi shift.
