The Box Two shifter offers exceptional performance with high-quality componentry. It features a hinged clamp made of extruded resin and steel, with a durable die cast aluminum top shell. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. Prime 9 is also terribly forgiving so you won’t have to constantly adjust your set-up.
