The BOX One Rear Derailleur is an 11 speed mountain derailleur that was designed for performance with durable 3D forged linkages as a way to greatly improve impact resistance. BOX also incorporated their tri-pack limited slip clutch system to drastically reduce derailleur cage bounce and chain slap.


  • Impact resistance is greatly improved by way of 3D forged construction
  • The Tri-Pack limited slip clutch is an advanced chain retention system that provides instant engagement and long-lasting chain dampening through the use of a one-way roller bearing and composite friction plates
  • Impact resistant, Pivot-Tech spring loaded cable stay keeps the cable, housing, and you out of harm's way
  • Precision sealed bearing pulleys
  • Wide cage fits up to 46T cassette cog, X-wide fits up to 50T
  • Not compatible with Shimano direct mount derailleur hangers (requires traditional derailleur hanger)
