Derailleur Hanger Alignment Gauge

If you are experiencing shifting issues there is a chance that your derailleur hanger might need to be aligned. A straight hanger is one of the keys to perfect shifting performance, just a slight knock or misalignment can spell trouble. Our Derailleur Hanger Alignment Gauge Tool is an easy to use tool that can precisely align your hanger back up without damaging your hanger or frame, to get that shifting performance back.
The tool threads into your hanger in place of the derailleur and is used as a pivoting point to measure the distance between the gauge and the rim at different points (normally 9, 12, and 6 o'clock positions). If the gauge isn't the same distance from the rim at each point, the arm of the tool is used as a lever to make small adjustments to tweak it back into place.

Note: Hangers are made from aluminium and don't hold up well to a lot of bending. If the hanger is substantially bent you will need to replace it as the metal will fatigue and fail if you try to bend it back into place.

Compatibility: Works with most 20-29" wheeled bikes. Some bikes may have clearance issues depending on the hanger position and the placement of the suspension pivots but it's impossible to predict which ones will have problems
