Marwi derailleur hanger/frame hook GH-280 Stevens 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 For this reason, gear hangers are originally made from 6061 cold-forged aluminum. There are many different models of gear hangers. This is due to the fact that the design of the gear hanger is related to the design of the dropout part of the frame. All Marwi gear hangers are 100% identical to the original gear hanger on your bike. And that's precisely why a Marwi gear hanger is the safest choice. 100% identical to the original gear hanger on your bike.
