bx-sh4-08cms-bk, The Box Four shifter's main features aren't strikingly different from Box Three's. The key difference is its 8-speed platform. We've chosen to modernize the 8-speed in much the same way we 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.SUPPORT MATERIAL Prime 9 Technology(TM)View Prime 9 Drivetrain Compatibility ManualHow is the Ebike variant different?View Prime 9 Comparison ChartView Prime 9 E-Bike Comparison ChartWhy Prime 9?
