Box Four Trigger Shifter

The Box Four shifter is designed specifically for 8-speed drivetrains. While it works well with Box components, it is generally compatible with other 8-speed systems, though we recommend checking your derailleur's pull ratio to ensure smooth indexing.

The multi-shift option allows you to shift through multiple gears with a single push of the lever, which is great for rapid acceleration. The single-shift option restricts you to one gear change per push, offering a more deliberate feel that can help prevent accidental double-shifts on rough terrain.

Yes, the Box Four is a solid choice for e-bikes. Its durable, simple construction is built to handle the increased torque and demands often associated with electric mountain bike drivetrains.

This shifter is designed exclusively for the right side of your handlebar, where it controls your rear derailleur.

The V2 release lever uses an MTB-style design that is positioned for intuitive, ergonomic access. It provides a crisp, responsive click that makes shifting feel precise and predictable, even when you are wearing gloves.
