bent rear derailleur hanger - advice(5 posts)

bent rear derailleur hanger - adviceturbo6bar

I got a new bike a couple weeks ago. It is great except for some damage received during shipping. Are derailleur hangers a generic item or specific to each frame? Do you think this damage is isolated to the hanger, or is the dropout possibly damaged? The bike was shipped with rear derailleur off the hanger, so I doubt the derailleur was damaged.

I emailed the builder earlier today, but I haven't received a response.

Are you 100% sure that it is damaged?

I guess your "fix" is going to depend on what material the rear derailleur hanger is made out of.

A dropout alignment tool is often known as a "bend it back tool". It looks like your hanger is Al. It's not that far off. I wouldn't be concerned about "straightening" it.

In most cases, a manufacturer will use one size dropout for as many bikes as possible. Some frames may require something unique. There is no industry standard that is being followed between manufacturers. An authorized dealer may have them in stock or should be able to get them easily.

Step 1: bend it back some. I usually break out the 12" adjustable wrench and eyeball it. You can take it to a shop where they have the official tool to make 100% that its straight too, but I'm a cheap bastard.

If that don't work, then

Step 2: buy another hanger and keep this one just in case.

The builder offered to reimburse the cost to straighten the hanger, but I'll give it a go myself. The only shop I trust to work on the bike is 45 minutes away from home.
