DEORE XT Di2 Rear Derailleur Medium Cage 12-speed delivers impact-ready trail reliability

What Our Gearhead® Experts Are Saying:


"I’ve set this up on everyday trail bikes where rocks and mistakes are part of the ride. The automatic impact recovery actually works, and the compact 9–45T pairing keeps it tucked out of harm’s way. It’s the kind of derailleur you stop worrying about once the ride gets rough."


When trails get tight, rocky, and unpredictable, we want a drivetrain that fades into the background and just works. The DEORE XT Di2 Rear Derailleur Medium Cage 12-speed is built for that kind of riding, where durability and composure matter more than shaving grams. With added ground clearance and a compact cage profile, it stays protected while we focus on line choice and momentum.


Wireless Di2 shifting delivers fast, clean gear changes under load, while Automatic Impact Recovery snaps the derailleur back into position after a hit. The SHIMANO SHADOW ES design keeps the profile slim and protected, and the solid cage and covered pulleys reduce the chance of trail debris ending the ride early. Optimized for use with a 9–45T cassette, this derailleur balances range, reliability, and confidence for daily trail riding.
