Marwi derailleur hanger GH-288 Cube Marwi offers a wide range of gear hangers (rear derailleur hangers) covering the majority of all bicycles equipped with a derailleur gear system. Gear hangers are designed to bend or break to prevent damage to the frame in the event of a fall. For this reason, gear hangers are originally made from 6061 cold-forged aluminium. 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 part. All Marwi gear hangers are 100% identical to the original gear hanger on your bike. And that is precisely why a Marwi gear hanger is the safest choice. 100% identical to the original gear hanger on your bike.
