BOX Three Prime 9 Shifter - 9-Speed Thumb

The BOX Three shifter combines performance and value at an affordable price point. It makes good use of nylon composites in both top and bottom shells as well as the levers. The shifter mechanism is simplified, and 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. Prime 9 technology offers the same range as a 12-speed drivetrain with fewer gears to shift through. The shifter features a resin top shell, extruded clamp, and fast action lever.
