Earring Union GH-139

All Union derailleur suspensions are 100% identical to the original derailleur suspensions on your bike, as they are made by the same manufacturer.
This ensures the correct strength and stiffness. Don t use anything other than OEM quality derailleur hangers, especially CNC machined from AL-6061 or 7075 aircraft aluminum .
They may be designed too hard and thus damage your frame.
This is why using a genuine Union derailleur hangers is your safest choice!
