- What to do with a bent derailleur hanger??
So I bent my rear derailleur, and I don't have the correct tools to fix it. Fear, not people, where there is a "wheel" there is a way... and I may have found a way.
So in this video, I'm going to straighten my bent rear derailleur hanger without the correct tool! It actually turned out to be a great way to fix a bent mech hanger.
There are many ways that your rear derailleur hanger can become damaged, and in fact, the hanger is designed to bend/break/twist, in order to save other parts of the bike. What a hearo part!!

Just what I needed, will give it a try tomorrow. Cheers 👍
Excellent! Glad that you found the video useful!! 😁
Good luck with your fix.
After years of riding and experimenting with DIY alligment tools - a simple old wheel! Brilliant. Thanks :)
Very clear! Be interesting to take the hanger off after correction and examine for crease lines or other indications of where it might break. And compare it to a new one.
Thanks great idea. Only problem is damaging the threads in the hanger. Maybe use a crescent wrench to get it straight and just measure with the other wheel. That wasy hanger threads are not damaged by putting part of the spare wheels axle in the hanger mount hole.
This works! I used a rear from another quick release and the threads weren't 100% so didn't use the second rear to actually do the bending, bent it by hand with some pliers/key through the hole (my hangar wasnt bent as badly as the one in this video), but then attached the second rear to make sure the alignment is alright.
Thanks for the vid!
Very interesting mate. Have not had this problem before, but good to know what to do, if need be! cheers!
Hey Damose, it worked surprisingly well! 👌🏼Glad you found the video interesting 😁
Local bike shop was going to charge me over $100 to fix this... thanks for the video. Cheers
100 dollars! Crazy how some bike shops will rip people off!
Bike shops are always a scam, remember that.
Bro same thing they charged me and after a month it started acting up again I said screw bike shops I’ll learn to do it myself
Support your LSB! They’re very nice people! 💩
Stoked! I bent mine on my Trance, but I have a spare set of cx wheels, so I'm in there, thanks.
Another helpful video J. Thanks for tips.
Hey Friend, glad you found the video helpful! 😁😁
Really good video ,Rj is the guy
I have learned to always lay my bike down on the left versus right side if there are no other options for upright standing. Even when one cannot visibly see a bend in the derailleur.....the immediate symptom is cassette gear shifting dysfuntion. Aluminum is very prone to metal fatigue but a bit of heat applied to a cold/bent derailleur can help especially in cold weather.
Not enough videos to find about straightening bended derailleur, but this tip is still nice.
👍🏽
great hack....iv just found a VITUS ARCOR frame down the scrap yard with a 105 group set on it plus Dura Ace shifters with a leather Turbo saddle im well happy so this tip will finish it off nicely thx for putting up ✌
As if you found that down at the scrap yard. That's a great find. Glad this little tip helped!! Enjoy 👍🏽
Made me feel better knowing it is not just me that this has happened to. Mine happened at the beginning of a group ride of all things when I clipped in to start moving and just like that, the group decided to stop at the light and I just didn't have enough speed to unclip and I just toppled over on the derailleur side. Same problem on mine, but I don't think I'll be this brave with my bike, LoL. Great video, though; thank you.
Sorry to hear about your little tumble, it was the second time that it happened to me. Mine was similar, a car didn't pull away at a green light and I was anticipating them to move.
As for the fix, it's not too difficult to be honest and it worked pretty well. Normally new hangers are pretty cheap so you could just grab a new one if that's easier. 😁
Safe riding friend!
@@JourdainColeman from what I've learned in other videos on this topic, a lot of new hangers aren't straight either! So it's worth checking the alignment (using a proper tool or a spare wheel) even after fitting a brand new hanger.
Great video. Thanks very much. Very helpful
Glad you enjoyed it!
In case emergency when there is no tools that is a great advice thanks from Bronx N.Y.
RJ is fantastic. I wtach his vids as well. Thanks for showing it. I saw his video and I was wondering if he used any special extension to the threaded axle of the wheel hub and your video showed that the answer is "no". Thanks for sharing it.
He has loads of great tips 👌🏼 - Glad you found the video helpful
Saved my ride, cheers
Glad it helped, Lee!! 👍🏽
Brilliant video. Great hack.
Cheers, Adisa! Glad you found the video useful.
I've never seen that method ...... Useful idea !
Thanks Paul! 😁
Good to know for the future 👍🏽.
Thanks for watching! Hopefully you'll never need this little tip!
Mr Fix it J good method useful to know just in case things happen 😀🙏🏿
Glad you think so, Carl! Hopefully you'll never have to use it 🤞🏽 (but just in case )
Should the deraileur free to move forward/ backward on the hanger?
Do you think that heating the hanger eg. hair dryer, will help reduce the chance of snapping the hanger?
Potentially. To be honest, the hanger isn't the strongest part so it bends relatively easy. It was easier to to do than I had originally thought.
I have the tool but it doesn't seem to work for me to allow the shifting to the last cog. ugh
I think you are supposed to screw in the extra wheel on the hanger by the non-drive side.... to avoid having to remove the cassette.
i have a titanium frame and the hanger is part of the frame. will this still work?
Hi Chris, If you have bent the frame then I'm not sure how it will be bending it back. I'm not sure if titanium loses strength once it's bent a couple of times. My instinct says... "Get a professional to check". My more daring side says, give it a try and see.
Let me know how you get on. Sorry to hear that this has happened to your frame.
I am afraid to put pressure on the frame as the power is transferred to the frame. So I removed hanger from the frame and put it in the vise and bended it.
Not a bad idea to remove it from the bike 👍🏽
Just saved me £20 quid, cheers mate 👍
No problem 👍 - Glad to help!
thanks to RJ
What a legend he is - ruclips.net/channel/UCaAK2FaxQ2xiBbAUVZsvDYQ
I notice he took apart the casette on the rim he used as a tool to bend back the hanger I wish he would have showed how that looked disassembled and pointed out a little better
Sorry Kim, I should have shown the wheel with the cassette removed. The wheel looked like this - upload.wikimedia.org/wikipedia/commons/8/89/Nabe_01_KMJ.jpg
Nice little hack, hopefully it'll never be needed though 🤞
Hopefully, Scott! I was actually super surprised to see it bent!
RJ the Bike guy did this 3 years ago
He sure did! That's how I learnt. I also mentioned him in the video and in the description. The man is a living legend.
