While everyone else keeps adding more and more gears, the Box One 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 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 Prime 9 chain is compatible with modern narrow/wide chainrings.
