While everyone else keeps adding more and more gears, the Box Four Prime 9 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 8 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 2-piece multi-shift lever allows for shifting of 3 gears at a time. 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.
