The Var Tools Derailleur Hanger tool is an essential addition to any home or professional workshop, designed to quickly and accurately check and realign derailleur hangers. A straight hanger is critical for crisp, reliable shifting, and this tool helps you diagnose misalignment caused by crashes, transport, or everyday wear. By referencing the wheel rim, it allows you to see even small deviations and gently bend the hanger back into the correct position, restoring smooth gear changes and helping to prevent premature drivetrain wear.
Built with durability in mind, this Var tool is made to withstand repeated use and the high forces sometimes required to straighten stubborn hangers. Its adjustable design works with most common frame and wheel sizes, making it suitable for road, gravel, and mountain bikes alike. Whether you are a dedicated home mechanic or a busy shop technician, the Var Tools Derailleur Hanger tool saves time, reduces guesswork, and helps you deliver precise shifting performance on every bike you service.
