Box Two Prime 9 Shifter (Select Option)

The Box Two shifter is the only shifter on the market (other than the Box One) that comes factory stock with a hinged clamp. Box Two is performance tier, so this shifter still maintains the durable cast aluminium top shell but trades out the Box One’s 1-piece pull-lever for a 2-piece resin and steel variant. All Prime 9 shifters take advantage of the 9-speed’s inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won’t have to constantly adjust your set-up. Available as a multi-shift option (pull several gears at once) or single-shift shifter option (a sound choice for e-bikes). Please select the option from the menu to suit your bike.

Features:

• Material: Glass Fibre / Nylon Composite, Steel, Aluminium Alloy
• Finish: Matte Onyx
• Hinged and Extruded Clamp
• 2 pc Pull Lever / Up to 3 Gears Per Shift* (Multi Shift Option)
• Die Cast Top Shell
• Fast Action Release Lever
• Prime 9 Technology
• Multi Shift Option Not Intended for E-Bike Use
• Single Shift Option Recommended for E-Bike Use
• Weight: 135g
