    Not sure when this exactly happened, but I first saw it when traveling through Mexico (must have his an unexpected tope!). Sorry about the lighting, but I had to use the car headlights:

    It looks like only the out part is warped. Can this be repaired, or does it look like I need a new rim?

    Here's a video of the wobble:

    thats close to nothing. Ride on. Had my 950 like that for two years in worst condition and never had an issue.

    Yep. My front and rear have looked like that for years.
    No biggie, just soft rims.

    Or you could find a wheel works company to re-roll it.

    But if it can't be felt while riding then why not just keep an eye on tyre wear?

    Then if it becomes an issue later do something about it.

    I have straightened my front rim several times using a 3 lb deadblow hammer. tip* remove rotors first for easier swinging. They're pricey but work great on a bunch of stuff.

    Just straightened mine out last week. Tire and rotors on, whole setup off the bike. Used a heavy 4' steel rod, small heavy mallet, and a cut up tube to protect the strike zone as if it's not scratched to shit already. Couple of few whacks and it's 80% better than it was. Might work better with the tire tire off.

    Sounds good. It does create some wobble and vibration when sitting on the center stand. I don't notice it while riding. I first noticed the dent in central Mexico, and we rode all the way to El Salvador with no problems (before getting into an accident, which is another story).

    I'll try to get it hammered back into shape. I was sort of prepared to buy a new one, but I was hoping not to have to. We're heading out on the continuation of our trip in five weeks, so I just want to make sure it's OK for riding.

    I generally run my wheels until they look like an egg.
    in the past I have cut a radius to match the wheel out of a 2x4 and used a heavy dead blow to pound them back into submission.That works well and does not scare the powder coating, works best with the tire off the wheel.
    I just replaced the front wheel on my ADV with an SE hoop.. lasted a month before it was "broken in":cry

    Check the spoke tension and adjust accordingly is the best advice.
    Like some have said its not worth the worry to staighten, i have some decent dents in my rims , been there for years.
    If you get it fixed, next week you'll hit another rock:lol3, plus i think it weakens the rim if you try to straighten them, alloy is like that.

    On the road! Finally!
    I have seen then crack badly after being straighten with a hammer - I suggest don't do it if can't feel it, just ride on.

    You can get away with hammering steel rims back in to shape, not so successful with alloy rims though- they really should only be re-rolled by a pro wheel works.

    Any tips on spoke tensions? I've read or been told to listen for a specific sound, but I am not exactly sure what that frequency would be. Also, I only have a traditional spoke wrench (without a torque function).

    This is a warped rim.

    After the first big hit, the wheel lost consistency, the tire started pushing out throught the first bend and it was like riding with a very low pressured tire.

    If not like this, keep on going

    Gustavo, your rim is a bad example for future generations.

    Your rim is not too bad, I would do nothing.
    I bended the front rims a couple of times.
    But it was really bad in the Danakil Dessert in Ethiopia.

    No change to repair it, but I was riding back to Addis 1.500 km without problems.

    If you decide to fix the rim yourself, after hammering a little bit, heat the area very well. That will let the molecules adjust. This prevents cracking as you bend it more by more hammering.

    I couldn’t repair the rim. So I had to ride 1500 km back to Addis with the bended and broken rim.
    And not only tarmac. 500 km have been sand and gravel.
    But the rim didn’t change until Addis, good stuff.
