Box One Shifter Clamp 31.8mm spare parts IMPORTANT NOTESThe 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.
