Shimano XT RD-RX827 Di2 12 Speed Rear Derailleur Long Cage

• Low-Profile SHADOW ES Design: A wedge-shaped, compact profile reduces the derailleur's exposed surface, allowing it to glance off rocks and trail obstacles with ease.

• Automatic Impact Recovery Function: The derailleur self-resets after absorbing hits, ensuring uninterrupted shifting and long-term reliability.

• Exceptional Durability: Wide-link construction and solid pulleys minimise flex and contamination, delivering smooth, consistent gear changes in all conditions.

• Advanced Chain Stabilisation: Dual-spring technology provides higher chain tension for superior chain retention and reduced slap on rough terrain.

• Protected Power Source: The Shimano BT-DN320 - opens in a new tab battery (sold separately) sits safely inside the derailleur body, shielded from vibration and impact yet easy to remove for charging.

Engineered for the toughest gravel adventures, the Shimano XT RD-RX827 Di2 12-Speed Rear Derailleur takes precision shifting and off-road durability to a new level. Incorporating Shimano's advanced SHADOW ES technology, this next-generation wireless Di2 rear derailleur delivers ultra-reliable performance across any terrain-from fast fire roads to unpredictable, rock-strewn trails.

With a low-profile wedge design, reinforced cage, and seamless chain stabiliser integration, the RX827 offers exceptional protection from impacts, while maintaining the fast, smooth, and quiet shifting Di2 is renowned for.

Rugged Design Meets Intelligent Recovery

Even when the trail strikes back, the RX827's automatic impact recovery function ensures your ride doesn't skip a beat. The derailleur's internal mechanism absorbs shock and instantly returns to its original position-so you can keep riding, often unaware there was even a rock strike.

Its wide-link construction, skid-plate protection, and solid pulley design further enhance strength and longevity, keeping shifting crisp and consistent through mud, dust, and debris.
