While everyone else keeps adding more and more gears, the Box Two Prime 9 Multi Shift Groupset takes a different approach. The engineers at Box decided that sometimes simple is better so they developed a groupset with a wide ratio range over only 9 cogs. The benefit is that fewer gears reduce the chain angle on the low end; making the chainline more direct across the whole range; improving component longevity and power transfer. The rear derailleur boasts a limited slip clutch with instant engagement and constant torque which prevents dropped chains and minimizes chain slap. The Prime 9 chain is compatible with modern narrow/wide chainrings. This is the single shift option; optimized for eMTB to keep the user from shifting multiple gears under load, significantly reducing the rate of bent teeth and broken chains.

Pieces installed easily. After the usual fussing to adjust the derailleur , shifting is predictable and runs quietly except during actual shift. I needed a wide range, strong drive for an ebike modification, Jim
