SRAM GX Eagle 12sp Drivetrain Replacement BundleRestore that "new bike" feel and peak shifting performance with the SRAM GX Eagle 12sp Drivetrain Replacement Bundle. Instead of patching a worn system, this complete kit ensures every contact point—from the chainring teeth to the cassette cogs—is perfectly synced for a smooth, silent ride.What’s in the Bundle? SRAM XG-1275 Eagle Cassette (10-52T or 10-50T): The legendary Full Pin™ technology offers a massive gear range with lightweight durability. SRAM GX Eagle 12-Speed Chain: Engineered with Flow Link™ geometry for reduced friction and longer life. SRAM X-Sync 2 Steel Chainring: Designed for maximum chain control, the rugged steel construction outlasts aluminum equivalents by a significant margin. SRAM GX Derailleur Pulley Wheels: High-quality replacement jockey wheels to eliminate drivetrain drag and sharpen shifting response. Technical Specs: Speed: 12-Speed Compatibility: All SRAM Eagle™ Ecosystem components Cassette Driver Body: Requires XD™ Driver Pro-Tip: For the best results, we recommend using the SRAM Slickwire Shift Cable Set (sold separately) during installation to ensure your derailleur handles this new kit with absolute precision.Why Replace the Whole Drivetrain?A drivetrain is an ecosystem, not just a collection of parts. Replacing components individually often leads to "ghost shifting" or premature wear because: Uniform Wear: A new chain on an old cassette will "skip" under load because the metal has stretched and worn to different profiles. Increased Longevity: Installing a fresh chainring and cassette simultaneously ensures the chain seats perfectly, preventing the "grinding" feel associated with mismatched wear. Cost Efficiency: By refreshing the full system now, you prevent a worn chain from "eating" your expensive cassette, ultimately saving you money and shop time in the long run. Shifting Precision: New pulley wheels and a crisp chainring restore the tactile, snap-action shifting that the GX Eagle group is famous for. SRAM Warranty
