Shimano Deore XT Di2 RD-M8260 Rear Derailleur Black, SGS, 12-Speed

What Our Gearhead(R) Experts Are Saying: "I'm blown away by how consistent and fast the shifting is, especially when I'm climbing or mid-descent. The fact that it pulls power directly from the bike's battery means I never have to stress about charging a second battery, and features like FREE SHIFT make descending smoother than ever." We ride harder and faster knowing the Shimano XT Long Cage Di2 Rear Derailleur for E-MTBs has our back on the trail. Whether we're running a tough-as-nails LINKGLIDE 11-speed drivetrain or opting for the ultra-precise HYPERGLIDE+ 12-speed setup, this derailleur handles the terrain without missing a shift. Shimano pulls from its proven XT lineage, integrating Di2 wireless shifting into a trail-ready package that runs directly off the e-bike's battery. This long cage derailleur was made for aggressive lines and unpredictable terrain. It's armored with a wide-link structure, a durable aluminum cage, and a protective skid plate to shrug off hits. SHADOW ES tech adds chain stability in all conditions, and Automatic Impact Recovery ensures you're never out of alignment for long. With advanced AUTO and FREE SHIFT functionality, you can shift while pedaling or coasting-letting us stay focused on the ride, not our gears.
