Hanger Genie 2.0 Hanger Alignment Tool

The derailleur hanger is the part of the bike most likely to bend. It's a sacrificial alignment piece: a soft aluminum bracket that bolts the rear derailleur to the frame and is built to deform first when the bike falls on its drive side. Once it's bent (even a fraction of a degree) every shift on the cassette becomes a small fight. The cable pulls the derailleur to where the index command says, but the derailleur arrives a few millimeters off the cog the rider asked for. Modern 11- and 12-speed drivetrains punish even half a millimeter of misalignment with sloppy shifts. The Hanger Genie 2.0 brings the hanger back to where the drivetrain expects it.

What changed in the 2.0

The 2.0 is the second generation of our hanger alignment tool, redesigned around the parts of the original that wore: the head and the axle interface.

• Welded head with sealed bearing thread-in axle. The thread-in axle on the original Hanger Genie carried a service bearing; on the 2.0 the bearing is sealed and runs in a welded head. Smoother under load, longer service interval.
• Extended thread-in axle provides additional clearance, which matters specifically on modern full-suspension frames where the chainstay yoke crowds the hanger area.
• Lockable measuring gauge. Set the gauge to a measurement, lock it, reposition the tool around the wheel without losing the reference. The original gauge had to be re-set at each rotation; the lock saves a real amount of bench time across a hanger session.
• Rotating bottom part clears the frame and accessories during rotation, so you don't have to remove the wheel or fight the chainstay to swing the tool to the next reference position.
• Improved tolerance on every machined surface vs. the original 1602/2.

Compatibility

The 2.0 fits bikes with the most common wheel sizes:

• 26″
• 27.5″ / 650B
• 29″ / 700

Road, gravel, MTB, e-bike, hardtail, full-suspension; the tool's measurement procedure is the same across the entire fleet.

Made in Slovenia, since 1919

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 2.0's welded-head-with-sealed-bearing design is the kind of small refinement that turns a tool we recommended into a tool we now keep on our own bench. The original Hanger Genie remains in the catalog for shops that want a simpler entry; the 2.0 is the daily driver.

Pro tip from our mechanics

The hanger is rarely the only thing out of true. Before you call a bent hanger fixed, run a quick gauge check on the rear dropouts with the Dropout Alignment Gauges 1692/4. If the dropouts are off, the hanger will check straight against gauges that are themselves measuring from a crooked reference. You'll fix the hanger to match a frame that isn't square, and the bike will still shift badly. Hanger after dropouts; never the other way around.
