SRAM GX Eagle Rear Derailleur Pulley Kit

The SRAM GX Eagle Rear Derailleur Pulley Kit delivers smooth shifting and long-lasting performance by pairing a 12T upper pulley with a 14T lower pulley. With precise tooth shaping and durable construction, it keeps your drivetrain running efficiently and extends the service life of your derailleur. This kit includes both pulleys and the correct bolts for easy installation and reliable fit.

Key Features and Benefits:

• 12T upper pulley with optimised tooth profile: The smaller top pulley guides the chain with reduced drag and precise engagement. This design supports crisp, accurate shifts across the cassette, ensuring each gear change is fast and controlled.
• 14T lower pulley with larger tooth design: The larger bottom pulley increases chain wrap and reduces friction under load. This added stability lowers drivetrain wear and boosts efficiency during long rides, giving a smoother ride feel and more consistent performance.
• Complete kit with 12.5mm and 14mm pulley bolts: Supplied with the correct hardware for direct replacement, the kit eliminates compatibility concerns and simplifies servicing. This ensures quick installation, secure fit, and dependable function without the need for extra parts.

Consistent shifting under load is a key concern for riders, and this pulley kit is built to address it. By combining different pulley sizes, it improves chain stability, reduces resistance, and enhances drivetrain lifespan. The robust materials and engineered tooth profiles mean fewer interruptions to performance, even when the drivetrain is under stress.

Keep your SRAM GX Eagle or Apex Eagle derailleur performing at its best with a simple upgrade that restores precision and reliability. This pulley kit is the practical choice for riders who value smooth operation and long-term durability.
