BOX Components BOX Two Prime 9 Speed Twin Lever Shifter Parts

Box’s goal with Prime 9 was to blend all the durability and reliability from a traditional 3×9 drivetrain with a 1x setup. Box Two is the performance middle-tier option within the Prime 9 lineup. With Prime 9 you still get the wide range offered on competing 12-speed setups, but with fewer shifts required to go up and down the gear range. The Box Two shifter maintains all the great functionality of the Box One but forgoes the 1 piece pull-lever from the flagship variant to bring the price down.

Who’s this item for: Any riders who need a wide range drivetrain to climb and descend steep terrain, but don’t want to spend hours tinkering with a 12-speed setup. 

Choose between single or multi-shift options. If you’re running an e-bike make sure to go with single-shift as the multi-shift option is not intended for use with e-bikes.

Number of gears: 9 speed, 11-50T gearing.

Weight: 135g

Materials: Glass fibre, nylon composite, steel, aluminium alloy.

Mount style: The Box Two shifter uses a hinged bar clamp so you won’t have to remove your other controls and grips to install it.

Shifter cable included: Yep! all box shifters come with a stainless steel shifter cable included. You’ll have to purchase a shifter cable housing separately though as these aren’t included. 

Compatibility: For use with the Box Prime 9 series only. This shifter won’t work with older 9-speed drivetrains due to a different cable pull ratio.
