Unior Tap

This tap is specifically designed for chasing or restoring threads on bicycle derailleur hangers. It ensures the derailleur mounting bolt seats correctly, which is critical for smooth shifting performance.

While it is sized for derailleur hangers, it will work on any component that requires an M10 x 1 thread. However, always verify the thread pitch of your specific part before attempting to use it.

Actually, the shorter length is a benefit. It allows you to maneuver the tool easily in the tight, confined spaces around the rear dropout where derailleur hangers are located.

This tap is primarily intended for cleaning and restoring damaged threads. While it is made of durable carbon steel, it is not designed for cutting new threads into unthreaded material.

Yes, you will need a standard tap handle or a T-handle wrench to hold and turn the tap. It does not come with a handle, so ensure you have one that can accommodate the square drive end of the tap.
