OneUp Components RADr Cage
  • The 2nd generation cage replaces both the inner and outer cage for Shimano GS (medium cage) Shadow+ rear derailleurs (Saint and Zee too)
  • Shorter than the original RAD cage for more clearance
  • RAD (Radial Appositioned Derailleur) cage moves the upper pulley wheel rearward of the cage pivot to optimize the derailleur for larger sprockets. As the derailleur moves into larger sprockets, the top pulley wheel automatically moves away to adjust the chain gap, no longer relying on just the B-Screw
  • Chain Wrap (cassette wear) and Free Chain Length (shift performance) are corrected to stock Shimano spec
  • Specific to 1x10 11-40/42 drivetrains
  • Inner and outer cages are made of 7075-T6 aluminum
  • 34g
