1. Sram GX Eagle Lunar
Derailleurs are supposed 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.
2. 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.
3. Shimano Deore RD-M5100
Thanks to the Shimano Shadow RD+ design, the Shimano Deore M5100 derailleur offers consistent shifting performance for mountain bikes in rough terrain.

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.
