Union GH-059 derailleur hanger

• Chrome-gray aluminum, a sturdy replacement for the point where the derailleur is mounted
• Total length: 50 mm; check that it matches your old hanger
• Mounted from the outside with 2 screws, so you can install it without removing anything else
• Center-to-center distance between the upper mounting point and derailleur hole: 35 mm, useful for comparison
• Before ordering, compare the measurements with the installed part: compatibility with Flyer and Bulls is for reference only
