Box Four Multi-Shift 8-Speed Shifter

The Box Four shifter's main features aren't strikingly different from Box Three's. The key difference is its 8-Speed platform. Box Components has chosen to modernize the 8-Speed in much the same way Box Components did the 9-Speed for Prime 9. Just like the Prime 9, the Box Four shifters take advantage of the "less is more" theme and exploit durability, simplicity, and reliability. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for E-Bikes).

There are also the "Compact" variations that are fitted out with upright shift levers. Any rider that either prefers to sit in a more upright position or has smaller hands will enjoy this configuration. The "Compact" comes with or without display.
