Box One Shifter Clamp 31.8mm
$24.99
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.
