Shimano Ultegra RD-R8000-GS 11-Speed Rear Derailleur – Medium Cage (Like New) Up for sale is a premium Shimano Ultegra RD-R8000 mechanical rear derailleur. The Story & Condition: I accidentally bought this to install on a 10-speed bike. Because this is an 11-speed component, it was incompatible with my setup. I rode it exactly twice before my mechanic explained the mismatch. It is practically brand new with almost zero wear, clean pulleys, and perfect functionality. Why People Love It: The Ultegra line is legendary among cyclists. It delivers the same crisp, lightning-fast shifting performance as Shimano's top-tier professional racing gear (Dura-Ace) but at a fraction of the cost. Specs:\

• Model: RD-R8000-GS (Mechanical)\
• Speed: 11-Speed\
• Cage Length: Medium Cage (GS) — measures 5 inches wheel-to-wheel.\
• Gearing Capacity: Supports larger climbing cassettes (from 11-28T up to 11-34T).\
• Technology: Low-profile SHADOW RD design tucks neatly under the frame to prevent crash damage. My compatibility mistake is your gain! Feel free to message me with any questions.
