SRAM NX EAGLE 12V REAR DERAILLEUR

This new SRAM NX Eagle™ rear derailleur features the proven 1x specific SRAM X-HORIZON™ design. The larger 14-tooth X-SYNC™ bottom pulley makes it easier to use an 11-50t or 10-50t cassette and also improves the overall smooth pedaling feel of the NX Eagle system. ROLLER BEARING CLUTCH™ Type-3 technology provides quiet performance and consistent durability.

FEATURES :

  • Completely new rear derailleur incorporating our proven X-HORIZON™ design and new ROLLER BEARING CLUTCH™ Type-3 technology.
  • The mounting system designed according to the Eagle™ environment and the positioning of the CAGE LOCK™ add robustness.
  • Eagle™ pulley technology provides greater efficiency, more precise shifting and quieter operation.

TECHNOLOGY:

EAGLE

Eagle™ technology represents our newest 1X drivetrain technology. Eagle™ is an easier and simpler to use, stronger and lighter drivetrain. Eagle™ features all-new 1X components, engineered for even greater strength and performance, while remaining significantly lighter than other drivetrain solutions. Eagle™ technology also offers an extended gear range of 520%, equivalent to a 2x11 drivetrain.

CAGE LOCK

CAGE LOCK™ technology in the rear derailleur makes removing and refitting the wheel, as well as installing the chain, faster and easier. Simply push the cage forward to create slack and then lock the derailleur in that position.

ROLLER BEARING CLUTCH

ROLLER BEARING CLUTCH™ rear derailleurs provide maximum drivetrain stability, even in the most demanding terrain. ROLLER BEARING CLUTCH™ technology eliminates derailleur kickback and prevents excessive chain slap without sacrificing precision.

X-ACTUATION

Specially designed for SRAM 1x™, X-ACTUATION™ provides precise and smooth shifting across the entire cassette.

X-HORIZON

The "straight parallelogram" design of the X-HORIZON™ rear derailleur limits all movement to a horizontal axis to prevent unintended shifting and reduce shifting force. For faster, more precise shifting, the large upper pulley clearance maintains consistent chain slack across all gears.

X-SYNC

SRAM X-SYNC™ 1x chainrings deliver the highest level of performance and durability. The large serrated square edges of SRAM X-SYNC™ engage the chain earlier than conventional triangular teeth. The sharp, narrow tooth profile, along with rounded chamfered edges, help handle a relaxed chain. To ensure the best possible performance in the mud, the X-SYNC™ chainrings have been fitted with mud evacuation cavities for the chain rollers and inner links. Designed in Germany, X-SYNC™ chainrings are an integral part of the SRAM 1x™ drivetrain.
