The SRAM Cagelock Feder XX1/X01 Eagle is a small but essential spare part designed specifically for SRAM’s high-end XX1 and X01 Eagle rear derailleurs. The Cagelock mechanism on these derailleurs allows you to lock the cage forward, making wheel removal and chain handling much easier. This spring ("Feder" in German) is a key component in that system, helping to keep the derailleur cage stable and ensuring crisp, reliable shifting on demanding mountain bike trails.
Replacing a worn or damaged Cagelock spring helps restore the precise function of your Eagle derailleur, especially if you ride frequently in rough terrain or harsh weather. Using an original SRAM part ensures proper fit and compatibility with the Eagle architecture, maintaining the performance you expect from your drivetrain. Ideal for riders who like to keep a small stock of critical spares, this component can extend the life of your derailleur and prevent minor issues from turning into ride-ending problems.
