SRAM RED XPLR AXS Rear Derailleur Mount Bolt Kit

No, this specific mounting kit is engineered exclusively for the SRAM RED XPLR AXS E1 rear derailleurs. It will not fit previous generations of SRAM AXS or mechanical derailleurs.

The B-washer, frame sleeve, and B-bolt are designed to work as a cohesive unit to maintain the precise interface between your derailleur and frame. Replacing the entire set ensures there is no play or misalignment, which is critical for the crisp shifting performance of the RED XPLR system.

If you are comfortable with basic drivetrain maintenance and have the correct torque wrench, you can install this yourself. However, because this is a critical connection point for your derailleur, ensure you follow the manufacturer's torque specifications exactly to avoid damaging your frame or derailleur hanger.

You should consider replacing these parts if you notice persistent shifting issues that cannot be resolved by standard indexing, or if you feel any play or movement when wiggling the derailleur body. Additionally, if the bolt head is rounded or the threads show signs of wear, it is time for a fresh set.

Yes, this kit includes the B-washer, frame sleeve, and B-bolt, which are the essential components required to secure the RED XPLR AXS E1 derailleur to your bike's hanger or frame interface.
