I show the process of replacing a broken derailleur hanger, including how I identified the replacement part. I bought this Specialized Rockhopper Comp a few years ago. I got a good price on it, but it was in rough shape. It had a broken derailleur hanger. The chain was also twisted a bit. Not sure how it happened. But it looked like something catastrophic happened.

Perfect 👍
I wonder if the chain doesn't have a master link??
Great job
Great bike mechanic?… Search your feelings, you know it to be true
I'm sorry, but it's absurd that you cut the chain without checking if it was in no condition for use. From what I saw, the chain was perfect and it was enough to distort it. at worst, you should have opened the chain and then reinstalled it with a new link. another absurdity is to tighten the new hook with pliers. unbelievable. finally, you spent an enormous amount of time explaining how to search for the dropout on google and did not explain that after placing the derailleur, it has to be adjusted and carefully checked whether or not it is warped, in order to avoid damage to the wheel and even a horrible accident due to a possible lock of the rear wheel. I think the video needs to be redone. , in order to maintain the quality and excellence of your posts.
Glad to see you back! I've returned to the Philippines. Up side is that skilled labor is very cheap. Custom paint and machining is often less than you'd pay for materials in the states. Down side is that everything but the most basic generic parts are special order from outside the country and may take ages to arrive. (China is only a week out, a package from Great Britain can take months.)
My rear derailleur is the same like in the video…but it starting to getting loose… chain flops everywhere…no tension…should I cut the chain shorter or is there any other trick?
Would you use a derailleur hanger alignment tool before putting the derailleur back on?
I've Actually used that same Rockhopper hangar to replace/fix a broken hangar on a non replaceable drop out (Gary Fisher hoo koo e koo) You have to carefully grind/dremmel the dropout into shape including removing the raised bit on the inside, widening the slot and drill for the holes (I think I removed a bit of the external lip of the hangar too) but it worked a treat, I see no reason you couldn't do the same with a lot of older steel frames. I see gorgeous lugged "mid range" (for the time) road frames with snapped off hangars all the time for chump change, too good to throw away but not worth the expense to have the dropout replaced. Seems like a fix that might be up your street RJ, if you can manufacture one of those quill seat-posts you could do that no problem.
Hot damn that is a spike in video quality. Iphone pro?
If you are going to be a mechanic , then do the job right , instead of using bolt cutter , use a chain breaker tool to break the chain, do not use pliers to squeeze to put the new hanger onto the frame. You wasted 3 minutes of your time searching for it , which you should have done before you did the video. And last thing use a blue locklite on the bolts to keep them from working back out. if you can not do this , then don't do videos and give people bad advice.
Derailluer hangers are just something the bike industry made up for mountain bikes to make consumers buy new bikes. It's pretty dumb there isnt a standard
Happy to hear "Hey viewers!" in my feed again. I always learn something from your videos. Thanks RJ
Thanks again
I suggest truing your hanger (Part Tool DAG, Abbey HAG etc.) before reattaching the derailleur, as it's very possible that whatever impact caused the derailleur to snap off possibly caused the rear tip of the chainstay to also get bent and out of alignment.
Very hood
Welcome back RJ 🤩👍
awesome man
Welcome back!🤓
Bike Jesus
This exact problem happened to me on my last ride! I changed gears and there was a lot of noise. Suddenly I wasn't able to pedal. I thought my chain had come off, and then I realized the whole rear derailleur was hanging off! The hanger had broken exactly as in your video. I mostly walked and occasionally rolled (risky and awkward) to a bike shop. Surprisingly, they gave the option to just replace the bracket; but the derailleur was a basic one and I upgraded to a better one for just over three times the cost of the bracket alone.
@Bikey McBeardface Are you RJ's representative, husband or lawyer to answer for him? Your opinion doesn't matter to me, and what you wrote just shows that you don't understand anything about bicycle mechanics. the video is intended to teach "the world" how to change a hook. it was not made to demonstrate the belt of this bike specifically. this way, all the steps have to be shown. Does Regina only make chains for motorcycles? KKKKKKK…..you really don't know anything…Mavic made cheap chains? HAHAHAHAHA…..go read more and study. Anyway, you're passing a certificate of ignorance. I liked your photo at the end of your post…pretty. I soon saw that you could only be a circus bicycle mechanic.
Nice to see you back RJ. I watch your videos even when I don't need to.
love seeing the video's again i missed them
Just use a photo to search. It's not like we live in the year 2015 or so.
Derailleur hangers started to need replacement with the introduction of aluminum and carbon frames. The steel ones were more malleable and less likely to break and could often be straightened slightly several times. Cheap bikes often came with steel separate hangers with the derailleur anyway. Too many proprietary standards out there!
