That will need replacing. If replaced with the same rim you can probably get away with reusing the spokes.

Hi kurt ,
you can do a trail straitening , I taco'd my front so bad it would not go through the fork arch .
Take the wheel off leaving the air in the tyre hold the wheel at 9.00 and 3.00 facing the bulge in the rim down at 12.00 find a nice hard tree root or something similar using about 60% of full force hit the "tyre " not the rim on the log three times check how far it has returned spinning the wheel around to the next bulge or continuing on that section or flipping it over if there is multiple directions of bends.
The tension in the spokes should return the rim to about 90% + of its original shape if the rim has not been to badly twisted your LBS should be able to re true it with spoke re tensioning
I did not believe this would work until I had to do it myself , I got my wheel back to almost as good as before but due to a huge flat spot as well I eventually replaced it.
This will get you home at least and depending on how much of a perfectionist with your wheel shape will roll for many more miles

after a bit of working out banging and swearing its straight again with a slight buckle
only a bit of truing up with the spokes required and its off again to see if we can do the same

cheers
Kurt
