Tune Tool 01, nipple key for UpSideDown-nipple, green

Special tool for working with UpSideDown nipples.

The Tune Tool 01 nipple key is designed for precise and easy wheel building with UpSideDown nipples. Its long shaft reaches even through deep-section rims, making lacing and adjustment much easier.

Markings on the tool handle allow precise pre-tensioning by reading quarter turns during the wheel-building process.
