Shimano Ultegra FD-R8000 Front Derailleur Cable Fixing Bolt Unit

This specific bolt unit (Y2BA98010) is engineered specifically for the Shimano Ultegra FD-R8000 front derailleur. While it may share similarities with other Shimano components, we recommend using only the part specified for your exact model to ensure proper cable clamping and safety.

This is the complete factory-spec fixing bolt unit, which includes the necessary hardware to secure your shift cable. It is designed to replace the entire assembly as a single, cohesive unit.

The most common reasons for replacement are stripped threads from over-tightening or corrosion that prevents the bolt from holding proper cable tension. If your cable slips during shifting or the bolt head is damaged, replacing it is the best way to restore reliable performance.

You will need a standard Allen key (hex wrench) to install this bolt. Ensure you use the correct size to avoid stripping the head, and consider using a torque wrench if you are unsure about how much pressure to apply.

It is generally recommended to apply a very light coating of grease to the threads to prevent seizing over time. Avoid using thread locker, as it can make future adjustments or cable replacements difficult.
