Box Four Prime 9 Derailleur (Black) (8 Speed) (Wide Cage) (Clutch)

Description

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 rear derailleur boasts a limited-slip clutch with instant engagement and constant torque which prevents dropped chains and minimizes chain slap.
