Material: made of steel

NEW Packing

We added a strong protective layer to fix the product and fill the box, so the product will not be damaged :)

2020/08/01 updata : Upgrade positioning block

Some buyers reported that the tool was not accurate enough. For this reason, we reduced the tolerance between the parts, and added a fixing screw on the block. Tighten this new screw by hand to easily fix the positioning block and rod.so that is zero gap.

2020/02/15 update : Upgrade Knob

thanks for your feedback, we already upgrade the plastic knob, It's solid now and won't break anymore.

Simple to use

The Derailleur Hanger Alignment Gauge can help solve a multitude of derailleur shifting problems, most notably with index shifting systems. This tool is extremely steady in operation.
The tool threads directly into the derailleur hanger. The gauge bar holds a gauge which marks the distance to the wheel. The gauge then is rotated with the wheel to the 3, 6, 9, and 12 o'clock positions, noting any differences in measurements. The alignment of the derailleur hanger is accomplished by applying pressure to the tool's arm. The results can be checked instantly.

Gauge bar made of heavy gauge, chrome plated steel
Adjusts to fit 20" to 29"+ wheels
Replaceable threaded tip
Upgraded large inner shaft for added strength
