Shimano XT 12-Speed Rear Derailleur-RD-M8150-SGS

Free shifting allows you to select the optimal gear while gliding through zigzag mountain trails or unpredictable maneuvers, so you can always maintain better balance and control, ready for sprints with fast and precise shifting performance. Optimized for riding on any track, the Hyperglide+ allows for quick overtaking under the greater chain load of an E-BIKE. Directly powered by a Shimano STEPS battery, it utilizes the E-TUBE PROJECT for custom-designed and diagnostic testing. Its low-profile design provides uninterrupted rear derailleur operation on a rugged bracket. The Shimano Shadow RD+ penetrates the E-TUBE EW-SD30085SHI.
