Box Two-E 9 Speed Rear Derailleur
Tri-Pack Limited Slip Clutch™
The Tri-Pack limited slip clutch™ is an innovative chain damper that vastly reduces derailleur cage bounce and chain slap. The system also maintains tension for better chain wrap. At its core is a clutch pack, that is capable of providing a large amount of force in a small package.
Durable 3D Forged Linkages
Impact resistance is greatly improved by way of forging — a key manufacturing process that strengthens critical components. Tested at the premier freeride event of the season — Red Bull® Rampage — this new construction has proven itself capable of performing at the highest level.
Impact resistant, spring-loaded cable stay keeps cable, housing & you out of harm’s way.
