Marwi derailleur hanger/frame hook GH-268 Decathlon Marwi offers a wide range of gear hangers (rear derailleur hangers) covering the majority of all bikes equipped with a derailleur shifting system. Gear hangers are designed to bend or break to prevent damage to the frame in the event of a fall. That's why gear hangers are originally made from 6061 cold-forged aluminum. There are many different models of gear hangers. This is because the design of the gear hanger is related to the design of the frame's dropout section. All Marwi gear hangers are 100% identical to the original gear hanger on your bicycle. And that is precisely why a Marwi gear hanger is the safest choice. 100% identical to the original gear hanger on your bicycle Gear hangers are designed to bend or break to prevent damage to the frame in the event of a fall.
