1. Shimano Deore XT RD-M8100
The Deore XT M8000 derailleur was already known for its smooth gear shifts and quiet chain operation. With the M8100, these features have been further improved, allowing for even faster shifting. To accommodate the extreme range of cassettes with 10-51 teeth, the derailleur has been completely redesigned. The indexing rollers are positioned to keep the chain at an optimal distance from the cassette in all gears. Their size has also increased to 13 teeth. This not only provides better chain guidance but also ensures a quieter and more efficient operation. Additionally, the Shadow+ system prevents annoying chain slap on uneven terrain. To achieve the best performance, Shimano recommends using this derailleur exclusively with 1x 12-speed drivetrains.
2. Shimano Deore XT RD-M8000
With the latest and completely revised version of the Deore XT group, the Japanese manufacturer elevates your shifting performance to a new level. The new XT group meets the diverse demands of cross-country bikers, trail bike enthusiasts, and enduro racers with equal conviction, presenting itself as the most versatile high-performance shifting group from Japan.
The Deore XT RD-M8000 rear derailleur features the optimized SHADOW+ technology with a flat angle of attack and an extremely low profile, keeping sensitive components out of harm's way. Shifting performance has been enhanced with newly designed jockey wheels optimized for cross-running chains. Additionally, you have the option to adjust the mechanism for minimal operating forces or maximum stability.
The Deore XT derailleur allows for precise and lightning-fast gear changes exactly when you need them, securely guiding the chain even on the roughest trails. Enduro fans can also forgo an additional chain guide, as the Shimano Clutch System keeps the chain under high tension.
The new Deore XT derailleur is suitable for regular 2x use as well as for bikers who prefer to ride with just one front chainring and 11 cogs at the rear, thanks to its large capacity.

This is a brand new derailleur specifically designed and optimized to work with a motor rather than a cable. The AXS™ components allow for precise customization and maintenance of the system through the AXS™ app, tailored to the preferences of each rider. Its shortened fork head provides an additional 10 mm of clearance between the derailleur and the ground, enabling better chain wrap on the cassette. It can be fixed more inward and forward than a mechanical Eagle™ derailleur. The Eagle AXS™ derailleur is smart enough to protect itself with its extremely strong overload clutch function. In the event of a collision, the motor drive disengages, allowing the derailleur to move freely before immediately returning to its position without the rider noticing. The system is waterproof and dustproof to IP69K standards, allowing you to ride through streams and mud puddles and perform high-pressure cleaning after each ride.
Product benefits: Easy and wireless shifting (128-bit encoding). Quiet, secure, and smooth transmission, regardless of terrain. Customize and control the system through the app according to your needs. To protect against impacts, the system features an overload clutch that disengages upon impact and returns to the desired position.
