Box Four Prime 9 Cassette (Black) (8 Speed) (Shimano HG) (11-42T)

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.

Features:

• 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 Four features 8 speeds with Prime 9 Technology
