SuperB Derailleur Hanger Alignment Gauge Tool Needs Images Who's this item for: AnyA misaligned hanger is often the main culprit behind poor shifting and a tweaked hanger will make it impossible to get your drivetrain running smoothly in every gear. All it takes is a bit of a knock from a rock or log, putting your bike down the wrong way, or a crash, and suddenly your gears are all over the place. The worst thing is that the hanger often looks fine but can be juuust wonky enough to make your gears skip a little and drive you insane.
