The SRAM Schaltwerkfeder X.0 is a replacement derailleur spring designed specifically for SRAM X.0 rear derailleurs. Over time, the return spring in a derailleur can lose tension due to heavy use, contamination, or simple wear, leading to sluggish shifting and poor chain control. By replacing the worn spring with the SRAM Schaltwerkfeder X.0, you restore crisp, positive shifting performance and ensure that your derailleur cage snaps back into position with the precision you expect from a high-end SRAM drivetrain.
This small but essential component is ideal for riders who want to extend the life of their existing X.0 rear derailleur instead of replacing the entire unit. It is particularly useful for mountain bikers and aggressive riders who demand reliable shifting in rough terrain, where a strong return spring helps keep the chain stable over roots, rocks, and drops. Whether you are refreshing an older bike or performing a complete drivetrain service, the SRAM Schaltwerkfeder X.0 offers a cost-effective way to regain factory-fresh shifting feel and maintain the performance of your SRAM X.0 setup.
