Risk Titanium R8000 Rear Derailleur Mounting Bolt RT113

The Risk Titanium R8000 Rear Derailleur Mounting Bolt (RT113) is a precision replacement fastener for Shimano road rear derailleurs. Machined from corrosion-resistant titanium alloy, it replaces the OEM steel derailleur fixing bolt to reduce weight while maintaining secure attachment to the derailleur hanger.

Designed specifically around the mounting interface used on Ultegra R8000-series rear derailleurs, this bolt is ideal for lightweight road builds, wet-climate riding, or routine service where long-term corrosion resistance and clean serviceability are priorities.
