Derailleur Bolt/Screw Kit, S100

The SRAM Derailleur Bolt/Screw Kit, S100 is a targeted refresh kit for keeping a SRAM rear derailleur tight, correctly aligned, and service-ready after wear, corrosion, or a lost fastener. It replaces key small parts that can compromise shifting precision when hardware loosens or gets damaged during routine maintenance.

• SRAM derailleur hardware replacement - Restores secure fastening where worn or missing bolts/screws can lead to play and inconsistent shifting
• B-bolt/axle kit included - Replaces a critical derailleur interface point to help maintain stable derailleur positioning
• Complete B-bolt/axle kit contents - Includes aluminum B-bolt/axle, dust shield, and ring clip for a more complete, correct reassembly
• Service-friendly small-parts solution - Helps streamline repairs and overhauls without replacing the full derailleur
