BOX One Shifter Clamp 31.8mm

BOX One Shifter Clamp 31.8mm
Color: Black
Please select options Unavailable


The Box One 31.8 shifter clamp is an accessory that converts any Box shifter to be compatible with modern drop handlebars found on gravel, cyclocross, and commuter bikes. While these bikes traditionally come with clutchless 2-by drive-trains, the addition of this clamp makes the conversion to a more user-friendly and durable Prime 9 drive-train affordable and simple.
