Dedicated to improving our components through rider feedback, Box drivetrains have been further refined to increase overall performance and enhance the user experience. The end result is more robust systems that provide precise control and increased range across any type of terrain. All second-generation derailleurs now include the following updates:
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* the clutch force with a simple Torx®-equipped multi-tool. (*Box One™ only)
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.
