The new Two Series 11 Speed Enduro MTB Rear Derailleur is the second generation mountain bike drivetrain from Box Components intended for entry level riders.

The patent pending TRI-PACK™ CLUTCH technology reduces chain movement and maintains chain tension. Housed in a glass 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 46T, the Box Two 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.
