Save the frame. Replace the derailleur hanger.
Merlin frames are among the most durable, most reliable builds in the world. Like all high-quality framesets, if they do have an Achilles' heel, it's the derailleur hanger. Anyone who has ever bent or snapped a hanger knows that this is by design, as it sacrifices the small, replaceable part to protect the integral-to-the-frame dropout and the derailleur. As such, Merlin offers the Derailleur Hanger Extralight/CrusherTi as a replacement part for cyclists with the misfortune of having snapped, bent, or otherwise damaged their stock derailleur hangers.
