Product Details

Shimano RD-5800 105 11-Speed Rear Derailleur

Following in the footsteps of Dura-Ace and Ultegra, this is the RD-5800 is the first 11-speed derailleur in Shimano's most popular road groupset - 105.

  • The Dura-Ace-derived, super stiff, wide link design increases rigidity and makes for fast and accurate changes across the 11-speed cassette.
  • The lighter spring rate delivers a super light action.
  • Large 11 tooth pulley wheels increase service life and reduce noise.
  • Available in two versions: SS for cassettes up to 28t, and longer arm GS for cassettes up to 32t.
  • Weight: 248g - based upon weighing a Shimano RD-5800GS 105 11-Speed Rear Derailleur at Bike Co-op HQ in May 2015.
  • Be aware that cycling equipment specifications can change without notice so please regard our published weights as an honest but approximate guide.
