A bent hanger is behind most shifting that can't be adjusted out. This gauge measures the hanger against the wheel rim and lets you straighten it back into line.

Highlights

  • Measures and straightens derailleur hangers
  • Fixes most indexed-shifting issues caused by a bent hanger
  • Updated design fits more frames, including thru-axle
  • Works with wheel sizes 20 to 29 in

Using it

Thread the gauge into the hanger, use the rear wheel rim as the reference, and check at several points around the rim, straightening gradually.

Compatibility & fit

Frames with a threaded derailleur hanger, quick-release or thru-axle, and wheels from 20 to 29 in.
