While everyone else keeps adding more and more gears, the Box Two 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.
- Prime 9 Technology offers fewer gears with wider spacing to ease set-up, provide a better chain line, and result in less wear and tear
- Ultra-wide ratio with consistent progression and fits standard HG freehub bodies (Not compatible with XD or Microspline)
- Box Two features hardened steel cogs pinned to aluminum spiders and an ED black finish
Freehub Body: Standard HG (Shimano/SRAM)
