.one. 11 Speed Rear Derailleur

P/N: 250284

DER BOX RR ONE 11s BK

  • Patent pending CamClutch™ technology reduces chain movement and maintains chain tension
  • Housed in a carbon fiber/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
  • 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™ 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
