Unior Hanger Genie 2.0

Even a slight bend in your derailleur hanger can cause poor shifting, chain noise, or skipping gears. This tool allows you to measure the alignment relative to your wheel rim and apply the precise leverage needed to straighten it, which is nearly impossible to do by eye.

It is designed to be compatible with the vast majority of standard derailleur hangers found on mountain, road, and gravel bikes. Because it mounts directly to the hanger, it works regardless of the bike's frame material or specific drivetrain brand.

While it is a professional-grade instrument, the process is straightforward. You simply thread the tool into the hanger, rotate the gauge to check the distance against the rim at different points, and use the handle to gently bend the hanger back into alignment.

The Hanger Genie 2.0 weighs 1134 grams, which gives it a substantial, high-quality feel that is necessary for applying consistent leverage. It is designed to be sturdy, so it is best kept in a toolbox or hung on a workshop wall rather than carried in a saddlebag.

When used correctly, it is designed to safely adjust the hanger without causing damage. The key is to apply slow, steady pressure rather than sudden force, allowing the metal to bend gradually back into its proper position.
