DESCRIPTION

Adjustable Tri-Pack Limited Slip Clutch™

The Adjustable 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. Clutch force can be adjusted to give the user the ability to tune their setup to the desired balance of shifter feel and chain retention. This version is also serviceable.

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.

Pivot-Tech™

Impact resistant, spring-loaded cable stay keeps cable, housing & you out of harm’s way.

FAQ

No. Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs.

Box 11 speed derailleurs are not compatible with SRAM 11 speed road shifters. They can however be used with Shimano 11 speed road shifters (requires a mode converter like Wolf Tooth's Tan Pan).
