Box One 11 Speed Rear Derailleur
Fine tune input at the shifter and set chain tension accordingly with Tri-Pack™ Clutch technology. This advanced chain retention system provides instant engagement and long-lasting chain dampening through the use of a one-way roller bearing and composite friction plates. Housed in the lower knuckle, Tri-Pack™ is both user-friendly and easy to maintain, allowing riders to adjust clutch force* with a simple Hex key.
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 levels and comes standard on all second-generation Box derailleurs.
Impact resistant, spring-loaded cable stay keeps cable, housing & you out of harm’s way.

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).
