The derailleur hanger, a sensitive and crucial part of the geared bicycle and regardless of drivetrain quality or adjustment, a poorly aligned derailleur hanger can make your bike almost un-rideable. With some modern drivetrains putting 13 cogs where we used to put just 8, it becomes exceedingly important for your derailleur hanger to be as close to perfect as possible. The brilliant minds at Abbey Bike Tools have designed a tool that allows for nearly perfect hanger alignment, while simultaneously making all other derailleur hanger alignment tools look like children's toys.

Introducing the H.A.G. (Hanger Alignment Gauge) from Abbey Bike Tools, precision machined with tolerances as low as .0063mm — for a practical comparison divide the average human hair, which is roughly 101.6 micrometers, into 16.  The H.A.G is likely the finest hanger alignment tool we've ever seen. Designed to be compact, as well as strong, the H.A.G can bend even the most stubborn hangers, and is perfect for both professional and home mechanics. Built with a surprising amount of adjustability, the H.A.G. is equipped to effortlessly tackle any bike, from full suspension, to fendered commuters.

With the addition of the new Abbey Lever Setter, you can use your H.A.G. tool to set the height of your shift or brake levers on either your road or mountain bike.
