The HAG is Abbey's derailleur hanger alignment gauge, built to check and correct hanger alignment to the tolerances modern multi-speed drivetrains need.

Highlights

  • Tolerances as tight as a quarter of a thousandth of an inch (roughly 0.0063mm) in critical dimensions
  • Lockable feeler so a measurement isn't lost after bumping the tyre
  • Top half rotates clear of fender stays and frame tubes
  • Feeler gauge stick stores inside the tool for travel
  • T-bolt extends further for hangers tucked behind full-suspension linkages

Serviceability

Rebuildable — the brass bushing in the T-bolt can be replaced in the field, though Abbey recommends returning the tool for a full rebuild.

Compatibility & fit

Fits standard rear derailleur hangers. Replacement HAG Gauge Sticks and Thread Caps are sold separately. Made in Bend, Oregon.

Abbey Bike Tools doesn't publish fixed consumer warranty terms for this item, so cover is assessed against manufacturing defects under normal workshop use, and for warranty support, return the product to Tune Cycles and we'll manage the claim with Abbey Bike Tools' Australian distributor.
