Best selling Rear derailleurs
Here's a ranking of the best products in this category. To give you a quick overview, we've also added some key information about the products.
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 guidance for the chain 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 only with 1x 12-speed drivetrains.
2. Sram GX Eagle Lunar
Derailleurs are meant to do their job, whether climbing under load or during the final meters of a race stage. The GX Eagle derailleur reliably fulfills this task. An improved architecture ensures even better chain management. It has been designed to work seamlessly with the new 10-52 tooth cassettes while remaining fully backward compatible with 10-50. We leave the choice to the rider, as it should be. Part of the Eagle color system, it matches any chain and cassette color you choose. The GX Eagle derailleur simply always does its job.

7. 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 and 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.
