5. Sram X01 Eagle AXS Lunar
This is a brand new derailleur specifically designed and optimized to work with a motor rather than a cable. The AXS™ components allow the system to be adjusted and maintained as closely as possible to the preferences of each rider via the AXS™ app. 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 IP69K rated for water and dust resistance, 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 encryption). Quiet, secure, and smooth transmission, regardless of terrain. Customize the system through the app to suit your needs and control it. To protect against impacts, the system features an overload clutch that disengages upon impact and returns to the desired position.
Details: 1x12 speed drivetrain compatible. Compatible only with Sram X-Dome cassette. Max. cog size: 52 teeth. Overload clutch protection. Aluminum fork head. Adaptable (Sram application). Water and dust resistant system up to IP69K. Battery weight: 25 g (compatible with Reverb AXS seat post). Delivery without battery and charger.

10. Sram GX rear derailleur 1x11-speed long cage
Technologies
Cage Lock
Thanks to the Cage Lock technology in the derailleur, removing and installing the rear wheel as well as chain installation is faster and easier than ever. Simply push the cage forward to release the chain tension and lock it in place.
Roller Bearing Clutch
The Type 2 derailleur was designed for the X0 and X9 product families and offers maximum drive stability – even on rugged and highly demanding terrain. With Roller Bearing Clutch technology, the SRAM Type 2 puts an end to wobbly derailleurs and clunky chains – without sacrificing precision.
X-Actuation
The X-Actuation technology, specifically developed for SRAM 1X, ensures precise and consistent shifting across the entire 10-42 tooth cassette.
X-Horizon
The parallelogram design of this derailleur limits movement along the horizontal axis, eliminating so-called "ghost shifting" while simultaneously reducing shifting force. For faster and more accurate shifts, the large offset of the upper jockey wheel ensures a constant chain distance in every gear.
X-Sync
SRAM's X-Sync 1X chainrings provide maximum performance and durability. The long SRAM X-Sync tooth edges engage the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile, along with the rounded angled edges, support chain guiding. To deliver optimal performance even in muddy terrain, the X-Sync chainrings feature recesses for the removal of dirt and mud from the inner chain links and rollers. The X-Sync chainrings, made in Germany, are a crucial component of SRAM's 1X drivetrain.
