A bent derailleur hanger is the most common cause of poor shifting after a crash or a knock. The BBB PadAlign makes it easy to bend the hanger back into line with your wheel, so your rear derailleur shifts cleanly again.

Highlights

• Long, stiff profile with an accurate gauge for high precision
• Uses your wheel rim as the reference
• Rubber ends on the gauge protect the rim
• High-quality steel, built to last
• 295 g (BBB claimed)

How it works

Thread the PadAlign into the derailleur hanger in place of the derailleur, then use the gauge to compare the hanger to the rim at several points around the wheel. The long arm gives fine control as you bend it back into line.

Why it matters

Even a slightly bent hanger throws off indexing, causes noise and can push the derailleur into the spokes. Checking alignment is a quick job that should come before any fine-tuning of gears.

Compatibility & fit

For threaded derailleur hangers on bikes with a standard rear derailleur mount. Hangers can crack if bent too far; if yours is badly damaged, replace it. For a hanger check and gear tune, book it in with the Tune Cycles workshop.
