NEW 2018 VERSION - NOW AVAILABLE!
The latest One 11 Speed Enduro MTB Rear Derailleur from Box Components continues to be the centerpiece of Box's second generation mountain bike drivetrain.
The patent pending TRI-PACK™ CLUTCH technology reduces chain movement and maintains chain tension. Housed in a carbon fiber and nylon composite body, the clutch mechanism uses a clever, one-way friction plate to increase tension as the cage moves forward and release tension as it travels back. Box's patent pending PIVOT-TECH™ works to prevent damage in the event of crashes or trail-side impacts through the use of a spring loaded cable stop.
With a maximum tooth count of 46, the Box One 11 Speed Rear Derailleur can easily handle today’s gear ratios and wide range cassettes. The inner and outer cages are made of durable cold forged aluminum and feature jockey wheels with sealed precision pulley bearings to reduce friction and avoid contamination.
