Pathtaker Derailleur Hanger Alignment Tool

The Pathtaker derailleur hanger alignment tool is a precision tool for measuring and correcting misalignment in the bike’s derailleur hanger. The derailleur hanger is the small replaceable bracket on the frame that the rear derailleur mounts to. If it gets bent, for example in a crash, a tip-over, or during transport, the rear derailleur moves out of position and shifting is no longer accurate. This typically causes chain skipping, inconsistent shifting, and drivetrain noise, even if the rear derailleur itself is fine and correctly adjusted. With this tool, you can check and straighten the derailleur hanger so shifting becomes precise again, especially on indexed shifting systems.

• Fits most wheels: Compatible with wheel sizes from 20" to 29"
• Precise measurement and adjustment: Makes it easy to see whether the derailleur hanger is bent and to straighten it fully
• Solves shifting problems: Helps identify and fix the cause of most shifting problems quickly and efficiently
• For indexed shifting systems: Especially relevant where even small misalignment affects shifting precision
• For both home mechanics and workshops: A practical tool that saves time when troubleshooting shifting problems

The Pathtaker derailleur hanger alignment tool is a useful tool for cycling enthusiasts who want to ensure optimal shifting performance and avoid chasing shifting problems that are actually caused by a bent derailleur hanger.
