Sram Eagle GX X-HORIZON Rear Derailleur:

This new GX derailleur not only answers the Eagle drivetrains need for greater capacity, but its also the next evolution of our proven, 1x-specific X-HORIZON› design. The larger, 14-tooth X-SYNC lower pulley allows 10- to 50-tooth cassette, and also adds to Eagles overall smooth-pedaling feel. Our new, Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. And a redesigned, robust mounting system further improves the Eagle derailleurs performance and overall durability.

  • Speeds: 12 Speed
  • Material: Aluminum w/ Steel Pulley
  • Advertised Weight ~ 290g
  • Colors: Black
  • Outer Cage: Aluminum
  • Compatibility: All levels of Eagle drive-train systems
  • Inner Cage: Aluminum
  • Spring: Steel
  • Cage Size: Long
  • Max Tooth: 50t
  • Hardware: Stainless Steel
  • Cage Lock: With CAGE LOCK technology in the rear derailleur, wheel removal and installations well as chain installation becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
  • ROLLER BEARING CLUTCH: ROLLER BEARING CLUTCH rear derailleurs deliver maximum drivetrain stability even through the most punishing terrain. With ROLLER BEARING CLUTCH technology, derailleur bounce and chain slap are eliminated without sacrificing precision.
  • X-ACTUATION: Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette.
  • X-HORIZON: The X-HORIZON rear derailleurs straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.


SRAM Eagle GX X-ACTUATION Trigger Shifter:

The challenges of riding a mountain bike should be kept to roots, rocks, mud, trees, jumps, drops and breathing. Putting total control of your gear selection into the thumb of one hand, it’s simple to find the right gear, right now. The GX Eagle™ trigger shifter is the control center of the Eagle™ drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability.
  • Speeds: 12 Speed
  • Includes Discrete Clamp
  • Compatibility: All levels of Eagle™ drivetrain systems
  • Recommended Group: GX Eagle™
  • Material: Forged aluminum trigger
  • Color: Black
  • Includes Discrete Clamp
  • X-ACTUATION™: Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.
  • Zero Loss™: ZeroLoss simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle-ground where you're waiting for the shift to come. Gear changes are instant and precise.

SRAM Eagle GX 12 Speed Gripshifter

Three decades ago, SRAM was founded on a product called Grip Shift, and an idea that shifting a bike should be easier, better and more intuitive. The new Eagle™ Grip Shift includes new, robust internals that make it even more durable and its shifting performance more precise. But just like the original, it is total control in the palm of your hand.

  • Speeds: 12 Speed
  • Compatibility: All levels of Eagle™ drivetrain systems
  • Recommended Group: GX Eagle™
  • Includes grips
  • Color: Black
  • Gear Indication: No
  • Technology Highlights:
  • Advertised Weight ~ 144g (includes clamps, cable and JAWS™ lock-on grip)

  • JAWS: Once the Grip Shift shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to handlebar.
  • ROLLING THUNDER: Three rows of ball bearings provide zero friction or play—reducing the force needed to shift and promoting long-term performance under all weather conditions with Grip Shift.
  • SPEED METAL: Full metal indexing keeps shifting crisp and precise with Grip Shift.
  • X-ACTUATION: Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.

Sram Eagle GX Chain:

The GX Eagle™ chain is designed with SRAM’s Eagle™ geometry, the GX Eagle™ chain features solid pin construction, Eagle™ PowerLock® and smooth, efficient shifting that you can count on every time out.
  • Speeds: 12 Speed
  • Closing Link: PowerLock®
  • Outer Plate: Silver
  • Inner Plate: Black
  • Pin Treatment: Chrome
  • Advertised Weight ~ 258g (126 links)
  • Material: Outer link finish Nickel
  • Rivet Type: Solid pin
  • Recommended Group: GX Eagle™
  • Compatibility: All levles of Eagle™ drivetrain systems
  • Technology Highlights: PowerLock®, Flow Link
  • PowerLock®: SRAM chain engineers developed PowerLock® as a tool free, sure, and consistent way to connect our chains. While PowerLock® does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock® is good for a one-time application only.
  • Flow Link: Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.
