The Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-50T and fashioned with steel spiders. The derailleur exploits BOX's Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, although you'll forgo the hinged clamp and die-cast structure. And lastly, string it all together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your 2/3 by bike into the 21st century, then level up with this group!

Box's Prime 9 Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability.

FEATURES

  • Our Best All-Rounder Drivetrain for Aggressive Terrain
  • Prime 9 technology offers the same range as a 12-speed drivetrain, with fewer gears to shift through
  • Fewer parts, reduced weight, and increased durability
  • Prime 9 drivetrains significantly reduce the chain angle in the lowest gears, allowing the chain to run straighter across all gears, increasing the life of the chain and cassette
  • The 2-piece multi-shift pull lever allows for riders to move up to 3 gears per shift
  • The Prime 9 chain is compatible with modern narrow/wide chainrings, and resists stretching over time, and decreases wear on the cassette and chainring
  • The x-wide rear derailleur features a limited slip clutch, which engages instantly with constant torque for less chain slap, better chain engagement and no dropped chains
  • The 11-50t cassette offers ultra-wide ratio with consistent progressions
  • Single shift options are for eMTB to keep the user from shifting multiple gears under load, significantly reducing the rate of bent teeth and broken chains
  • Compatible with HG Freehub Bodies
  • Compatible with Standard Derailleur Hangers (Non Direct-Mount)
  • Compatible with most 10,11, & 12-speed wide / narrow chain rings. Prime 9 chain must be used.
