The Shimano Deore XT M8250 long-cage derailleur paired with a standard 10-51t M8200 cassette (cassette sold separate) gives all types of riders the range and robustness to tackle every trail on the mountain. With built-in Automatic Impact Recovery, a new, impact-deflecting wedge shape, and simple covered-pulley solutions, this derailleur stands up to harsh trail impacts and still retains its lightning-quick shifting speed and high level of performance.

• Di2 technology results in precise and clean wireless shifting
• Pinpoint, ultra-fast shifting, and a no-sacrifice 510% gear range
• Wide link structure, skid-plate design, durable aluminum plate and solid pulley add robustness and longevity
• Automatic Impact Recovery function instantly returns the derailleur motor to its original position after impact
• Shimano Shadow ES technology delivers a wedge-shaped design that reduces the derailleur’s front-facing surface area and eliminates edges that could catch on rocks and roots
• Tucked safely inside an enclosed space, the battery won’t budge even in rough terrain, while remaining easily removable for charging
• Solid pulley and shielded pulley teeth prevent trail debris from jamming up your flow
