The HAG is the last hanger alignment tool you'll ever have to buy. 

The derailleur hanger is the foundation for modern drivetrain to function properly. With modern bicycles getting up to 13 gears in the space we used to fit 8, it has never been more important to ensure the hanger is perfectly straight. Unfortunately, many of the current tools simply aren't capable of achieving that kind of precision.

We've gone the extra mile to make this tool half precision measuring instrument and half leverage bar.

Tolerances as tight as a quarter of a thousandth of an inch (.0063mm) in some critical dimensions of this tool.

Ability to lock the thickness so you don't have to guess your measurement after knocking it on the tyre.

The upper half of the tool will rotate out of the way of chainstays and frame tubes.

The feeler gauge stick stores in the upper half of the tool, very handy for the travelling mechanic.

The T-bolt extends beyond the tool to access problematic hangers found on some modern full-suspension bicycles.

Compact at just under 11" (28cm).

Repairable. Whilst your HAG should ideally be returned for a rebuild, it is possible to do this in the field by replacing the brass bushing in the T-bolt.

Compatible with the three most common wheel sizes, 26, 27.5/650B and 700/29) 

Made in Bend Oregon.
