SHIMANO DEORE XT Rear Derailleur (Di2 spec.) RD-M8250-SGS 12-speed

Shimano Deore XT Di2 RD-M8250-SGS Rear Derailleur

Wireless 12-speed Deore XT Di2. Long SGS cage for 10-51T HYPERGLIDE+ cassettes. It runs off its own removable battery, tucked inside a protected space so it stays put on rough ground. The battery is sold separately.

SHADOW ES keeps the chain stable and quiet, and Automatic Impact Recovery returns the derailleur to position after a knock. A wide link structure, skid plate, aluminium cage plates and covered pulleys round it out. Fitting a Di2 derailleur means pairing and setup in the E-TUBE app, so it's normally a workshop job.
