Abbey Bike Tools H.A.G. (Hanger Alignment Gauge) is a precision alignment tool designed to restore proper derailleur hanger alignment on modern geared bicycles. As drivetrains have advanced from 8-speed systems to 12- and 13-speed setups, accurate hanger alignment has become critical for reliable shifting, reduced drivetrain noise, and consistent indexing.
Precision machined for strength and repeatability, the H.A.G. is designed to measure and correct bent derailleur hangers across a wide range of bike types, including road, mountain, commuter, and full suspension bikes. Its adjustable design and rigid construction make it suitable for both professional workshop use and serious home mechanics.
Why Use Abbey H.A.G.
Bent derailleur hangers are one of the most common causes of poor shifting. The H.A.G. is designed to provide accurate derailleur hanger alignment measurement and controlled correction, allowing mechanics to resolve indexing problems at the source instead of chasing adjustment issues elsewhere in the drivetrain.
