Derailleur Hanger 321

I bet you’re wondering what a derailleur hanger is. It is a small piece of metal that is attached to the frame of your bike. It is also known as a mech hanger, mech dropout, cast hanger, mountain bike hanger and hanger dropout (the list is endless). Derailleur hangers are designed to absorb any impact and strain that would be focused on the frame of the bike.

We work hard to make sure all of our derailleur hangers have superior strength, amazing durability and great shifting. BETD derailleur hangers are your robust and premium, yet affordable upgrade from a standard cast hanger.
