Second day out with my bike and I got a branch in the rear wheel, the derailleur is now completely out of place... Do you think it's easily fixable?

It's a cube 140 TM 750, it's have a UDH derailleur hanger. I hesitate to check furtur alone i don't have torque system.
Does one of you have a similar issue on the past? did i have to changer the hanger? I will go to a pro but maybe i can i fix this myself?

Nothing broken! The UDH hanger havedo his job and have moved to prevent damage... So it's was easy to repair! But now i have to buy a torque system...
All good i'm happy

You can straighten the derailleur hanger using a special tool like this one :

Or get a shop to do it for you, but if the hanger is too badly bent you risk breaking it while trying to straighten it, so not a bad idea to get a couple so you have a spare on hand...good thing you have the UDH , they're easy to get hold of...the Park Tool tool is a bit expensive but very handy to have around, I've used mine on several occasions so I figure it's paid for itself

Thank you for your tips! Yes tomorow i go to a pro so i have the correct strength.
But yes i will buy a torque system after that and yes maybe a park tool

Glad you got it fixed. I came of my first bike at speed within the first couple of weeks and spent an age waiting for a new hanger. Now always keep a spare in stock and have a knockoff realignment tool.

Unfortunately the derailleur is easy to knock on things at the side of the trail, so easily bent out of shape.
