Will any rock do to practice with
no. use a derailleur hanger disalignment rock only, such as the parktool ROK-3056 ($39.90)
holy *** I laughed sooo hard 😂
No you need The Rock aka Dwayne Johnson!
@@oefzdegoeggl when you go to make a joke on a comment and someone’s already been there months ago with a better version.
Well done :)
@@oefzdegoeggl I totally agree. I bought the ROK-3056. That tool rocks!
Gotta say, was not expecting the rock lol.
It hurted me !!
That was a pro move.
@@captainkickstand Absolutely.
but it can happen during ride, rocks flying here and there
Haha
My son is 13 years old, so obviously I needed this video. I bought the tool and fixed it myself this time. Thanks for the excellent video and clear instruction!
Also remember to make sure replaceable hanger mount bolt(s) are tight. Loose bolts can also affect shifting
*Torqued
@@thegrowl2210 shut up
i have 2 spare hangers, i have bolts on each one of them, but you can use the bolts from the original to install the spare if you are careful not to loose them in the grass on the trail side
YOU ARE THE MAN!!!!!!! The hanger was bent and I was able to straighten it using an accurate straightedge held against the "flat" of the hanger. Thank you, Calvin and thank you, Park Tool.
Great video, well explained, straight to the point and easy to follow!
Did this today after dealing with rattling noises which neither cleaning, shifting adjustments nor a new chain could fix - and indeed, the derailleur was bent! A tiny adjustment has fixed all the rattling and shifting hick-ups, and I cannot tell you just how much of a RELIEVE it was!
So worth it! And now my partner is eager to check his bikes as well as he's had a collision with a branch in the spokes a while back.
Thank you Park Tool for your educational videos and thanks Calvin for explaining it so well. Your videos have already saved me a bunch of times!
They always leave me with a pretty good idea of what needs to be done - competent, capable and confident!
Just got mine today, and after removing the derailleur from the hanger, and following this video closely, I can't believe it. It was imperceptibly bent inwards, which the bike being new, the hanger was bent imperceptibly during shipping. Not uncommon, but I could've sworn it was aligned by eye. I could not have been more wrong. It was definitely bent, and this tool got the bike shifting so damn smooth it's ridiculous. I'm glad I just dropped the $80 on this awesome tool instead of buying a chain, and this and that. Nothing I did following Park Tool's video on derailleur adjustment really got it smoothed out. Because the dang hanger was bent.
NICE JOB Park Tools! :) I also own their small beam torque wrench, and man that makes that easy, too.
I've had shifting problems for 2 years and could not get my gears lined up. Finally bought this tool and took me 20 min to sort this out. Came of my bike a few times and landed on the rear derailleur. Great tool to have in your bike box. Thanks for the great video.
Excellent instructional video, as usual. Got my hanger straight and shifting is spot on.
Thank you for all of your videos! I'm ordering one of these tools now and can't believe I've been without this! Should take care of a lot of shifting issues, as I mostly ride rough rocky trails with derailleur strikes being rather common.
Calvin, thanks man! I’ve had shifting issues with one of my roads bikes that I picked up used. Sure enough, the hanger was bent. Your video helped me and my DAG-2.2 get things squared away 🚲👍🏻
One clue to a mis-aligned hanger is if there's a nutter standing next to your bike with a large rock in his hand :-)
piggybladder best comment here by far!
Hahaha
😂😂
The last two bikes I have purchased (brand spanking new) came with hanger alignment issues. And with these big ass cassettes we are using these days, alignment is critical. I have the older model DAG-1, and it fits nicely in my travel toolbox.
It's not necessarily the size of the cassette (you're talking about tooth count, right?). It's more about the spacing between cogs. Now that we are have 12 speeds, the spacing is very small which reduces the amount of tolerable error.
DAG older or newer is excellent tools and does great gob. Enjoy it!
I balked at the price but I use that tool way more than I figured I would. If you want to maintain your bike yourself, you need one. And like he says, I found out the hard way that hangers can be hard to get, so always keep one on hand. Loved the rock, all my derailleurs end up like that I think, lol.
Used it today to sort a friends bike. Took about 5 mins. Interestingly enough two other bike mechanics were not able to sort the gear skipping issues. 2nd bike I have sorted using this tool, so its paid for itself already
I didn’t have the tool. I used my hand to pull it out from bottom of derailleur and it worked. Thanks for the video, very useful.
The tool and video worked like a charm. Bike shifting great now. Thanks!
you bought a ,,$200.00 tool to fix a ,$2.00 part? hummm. I just take mine off and put on a 2/4 and smash it with a hammer.works every time 😁
@@kevinfrederick7956 It was an $80 tool and a bit more accurate than a hammer ;-)
@@brianmcdonnell9010 You need a better hammer!
I finally fixed my bike. I shot a laser parallel with my frame then measured to make sure my rear tire was in-line with my frame and come to find out it was 1/2" off so I used a dremel to grind the hanger about 1/8" back so the tire axle can go back on one side making my tire in a straight line. I then used this hanger tool to align my hanger. I got everything to 1/8" and WHAT A DIFFERENCE. Instead of only being able to shift half my gears and have them pop out of gear all the time it shifts like a Ferrari. I brought my bike to 3 bike shops and multiple times to those shops. Everyone just gave my bike back charged me for a tuneup and nothing ever changed......If you want it done right do it yourself!!! Im happy :)
This tool is a lifesaver
Saved me a trip to the shop! Thanks Calvin
I just realigned my hanger using the parktool tool and this guide... this US version is better and direct to the point than the UK counterpart that has lots of talking. 😅
Thanks Calvin, you're the best. When are you taking these instructional sessions on the road?
This video rocks...
Awesome informative video. Just bought a new bike so now....start collecting tools.
Another excellent Park Instructional video! Thank you!
My favourite tool at the shop, love it!
The rock? :)
Definitely the rock.
The rock smash kind of hurt to watch haha but great video. Learning that the planarization was the most important here thanks so much
Jesus christ the things you do to teach us. You deserve all our praise
I'm really starting to like part tools help videos its helped immensely with my bike thank you park tools really
great video. I needed a quick review before using my DAG tool. I did cringe BAD with the rock smashing lol
I almost had a heart arrest when he hit deraileur with a rock
I am going to have to buy this tool! my 11 yr old is s cause of frequency flyer trips to the local bike store for rear derailleur issues..
fantastic. thankyou. liked the rock demonstration. a little confronting, but point made clearly
My old frame doesn’t have a replaceable hanger. Changing gear on the second and third from largest cog doesnt index correctly. Hopefully my alignment tool will arrive today, and ill not break the hanger off. Thanks for this video, hopefully things will work out for me. Update- derailleur hanger was bent, now straight thanks to park tools
Glad it didn't break that would not be good!
Ya if it's an old steelie it should bend back, no problem.
Sunteți profesioniști. Vă urmăresc cu mult interes videoclipurile.
I need to get one, I have about 6 bent ones put away for when I get one of these, literally just bought another one for a weekend of bike parks
Love this tool but, man, I had a hell of a time finding the right sized seat bag for it! ;)
I love smashing my bike with a boulder! Funny stuff Park!
Can you use the rock in the other direction to fix a derailleur?
I dont have a derailleur hanger ( cheap bike). My derailleur is welded into the bike frame. While bunnyhopping i fell down and saw that the derailleur was bent towards the spokes of the wheel.
I just simply adjusted the barrel adjuster and shifts just fine with only half a second delay. If u dint have tools try turning ur barrel adjuster to match the derauiller wheel with the cogs. Works fineeeee asss hell.
Probably because your hanger wasn't terribly bent. If the damage is bad enough it can send your derailer into your spokes which could royally fuck your rear wheel and and total your derailer! You can also eat shit into oncoming traffic. Happy your bike works again but that's just false economy! Cheers
Excellent video 👍👍👍
Outstanding video. Thank you.
I flinched so hard when he hit the bike with a rock...
Dear you are best in the world keep it up👍
Derailleur hangers are intentionally designed as sacrificial pieces of equipment. they are like electric circuit breaker. hangers are designed to be strong enough to do it's job, and also to bend and brake, in case of crash or bash. The main idea here is that the force from the impact, regardless of the source of the impact, will follow the path on least resistance. The hanger is designed to vividly manifest itself as the path of least resistance, so it draws the force of the impact onto itself. the idea behind this design is to protect the frame and the derailleur from being bent or broken. If you think, this sacrificial piece saves you a frame, a derailleur and the hassle of replacing frame or equipment.... and the pile of money related to all this hassle.
He smacked the living H out of that derailleur just to make this video. I love this channel.
Just the best 🙏 - that man is just great 👍
I'm used gravel bike MARIN GESTALT x10.had the same problem,my chain rubbing the cassete after i fall the bike.slowly cycling back to home,and after check,my frame (dropout) was bent at the RD point,but the hanger are still ok.i used the adjustable spanner,to alignment back the dropout frame.almost 1 year,i never face any problem.but to have a SPARE HANGER,i think its a best idea.cant imagine if i'm broken it in the way long from my home and in the deep of forest..
Dude I can make make that tool, great informative videos when I need a repair video for bicycles, Park Tool are the best vids on youtube.
thanks!!! this helped, but it will need proper fix at shop
OMG.... the rock hit... these guys are serious. Park Tool for now on... 😂
This video is a lifesaver
Hice todo como lo dijeron pero por alguna razón la brecha de 3mm no me funciona tan bien, teniendo en cuenta de que tengo el grupo 105 completo. Baje la brecha a 2mm en los 4 puntos y ahora tiene la respuesta de un Dura-ace.
Creo que deberían aclarar que los 3mm, son para menos de 10 velocidades, y los de 2mm para mas de 10 velocidades.
I don't know why, but i gonna buy two, just because of the video.
Everybody should always have two in possession, one on the bike and another on standby. This is what almost nobody buys whenever they get a new bike or frameset.
Got the tool. Just need to get the Park Tool moustache and apron combo. Is there a part number for the big ole rock?
Did anybody else cuss him out when he wailed the bike with the rock?
Indeed. All I could think was "Couldn't you guys just find an Altus derailleur for that demonstration?"
I puckered and had a spit take.
@darkasthegrave or a Tourney?
how dare you speak poorly on Tourney
nope, savage demonstration
My bicycle is 6 years old. I have been having chain skipping in the back middle cogs, 3,4,5 mostly. I replaced the hanger, the cassette, the front crankset, and the derailleur. rear cogs 1,2,6,7,8 are ok. It makes my rides much less fun. I have adjusted the limits and the derailleur 20 times and it does not skip in the shop, only when I am riding, I don't know what to do next.
Did you try replacing your chain? A worn chain will wear out the sprockets, then if you replace the sprockets but not the chain, or the chain but not the sprockets, you'll get chain skipping.
Cassette or chain worn out replace both
same condition as mine. Try aligning the RD hanger as shown in the video
A true master will bash his derailleur with a rock because he knows he can fix it
Why you did not use a simple water leve gauge on the bar hanging instead of the using the rims for the alingment, thas what I would do actually..thanks :)
Just dont do this on a trek roscoe ive done 1000 alignments but for some reason a trek roscoe hanger snapped soon as i touched it very brittle
Fantastic video
Cant wait to buy my very own
Park Tool Rock RCK-1.0
Nice, but why monetize (so many ads in the video) for the instructions of an already expensive tool?
oh god this needs an R rating jesus christ
park tool best tool !
Is it advisable to use the straightening technique on a carbon frame? Does that risk messing up the drop-out or rear triangle? Or is it better to just replace the hanger if it's bent?
Good question. Aluminum and steel both have a yield point below their point of failure, or tensile point. You can bend both materials quite successfully. However with carbon fiber the yield point is equal to its tensile point. Carbon fiber flex certainly, but the point where it flexes enough to deform and stay bent is equal to the point where it breaks. Second however, it is very rare to see a carbon fiber hanger. These are aluminum, and will take a permanent set. It is done daily with good results. Third however, new hangers are most always made straight. However, the frames are not a consistent. So installing a new hanger on the bike it is best to check alignment. The fitting on the frames are not always perfect, so a new hanger will sit differently on different frames.
@@parktool 4th however. often alignment issues with new hangers can be a result of neglecting to take care and cleaning the hanger bed in the frame and some piece of dirt can keep the derailleur out o alignment, creek and introduce potential for unwanted movement. if derailleur is not well seated because of dirt, this means some screw will not have gripped properly and cause further issues
7 years, my bike rear derailleur in bad shape, bought 1 cheap tool and done the work!
Nice and clear. Thanks.
How about checking for a bent derailleur cage? Is there a way to accurately check this, like there is for the hanger?
Good question. Not a good answer. By sight is how. However, not all derailleurs are designed to be "straight and square". View the cage from the top, and the back, as it a three dimensional issue. Compare the suspect model to a new one. Repair is a different issue. The cheaper the derailleur, the more likely bending back may help. Those are not typically the ones to worry about.
That rock part omg 😂😂😂😂
Hi, my derailleur has the hanger as a part of it, so it's not detachable and looks kinda like a hook.
It has a screw for tightening and that's it.
How would I go and straighten it out?
Thanks!
Armin: Get a better bicycle.
@@lazurm such brains, much smart
Great video!
I am looking for a video on How to lube a rear Derailleur. Thanks in advance. :)
Usually lubing the chain adequately will spread the lube everywhere the chain might go. Just shift to all the gears next time you clean and oil the chain
I managed to snap my hanger 😕 the frame and broken hanger has three fastener holds but I have a replacement hanger that fits but only two fastener holes. Would this be ok to use if the shape fits?
Rachel, even if it works I'd say the answer to your question about replacing a hanger with less fastener holes than the original is not to do it.
eh, i thought I did this exactly like shown but I think it's not going into the smallest cog due to something with the lever, It feels different when trying to get to that last one when shifting.
professional brick
Dead Pan rock smash made my day :)
Question for the Park Tools gurus. I have used the alignment tool successfully for derailleurs that are easily removed from the hanger. I am now faced with a Shimano 7 speed derailleur that doesn't expose the bolt connecting the derailleur to the hanger. It is covered by a piece of plastic and the two limit screws. How do I get to the bolt to separate the derailleur from the hanger? Help!!! :-)
There are certainly models that have use a "bolt on hanger", which attaches to the open face of the dropout. Generally older bikes and less expensive bikes do this. The pivot of the derailleur is riveted to this bracket, and there is no bolt to remove and thread the DAG-2.2 into. If so, some careful use of a pair of slip joint pliers and a steady hand can bring it back enough.
Park Tool Thanks
00:39 that escalated rapidly xd
is the bending adjustment recommended for carbon frame bikes?
Yes it is. Carbon Bikes have a softer aluminum hanger so that if it breaks it does not ruin the frame. Proper alignment of that hanger is crucial to the operation of any shifting system.
and if your hanger is straight and in true thread it in and tape it to the seat stay, boom. Truing stand.
Can you make a video on Shimano acera jokey wheel cage repairing 6:31
what web do you use for your hangers?
Ensuring the wheel is straight in the frame is best done with the bike standing on the ground.
Solid video!
Just bought a replacement hanger
Do i need to align it even if it's new? Coz that's what others said to me in a bike forum. I thought you just need to slap it and that's it.
It is good to check alignment. New hangers come aligned and straight. However, frames are often not consistent, and a new hanger not be straight. Check and aligning a new hanger effectively "customizes" it to your frame.
dear park tool
I can't afford this tool.
sincerely, me
Same here. as Much as I Love Park tool I Just Ordered a copy cat X-Tools Pro Gear Hanger Alignment Tool. its on Clarence $35 + shipping on Chain reaction Cycles..
Make one:
ua-cam.com/video/sWdO4dnu18g/v-deo.html
Visit your local bike co-op!
Just take this one:
www.aliexpress.com/item/4000561680367.html?spm=a2g0s.8937460.0.0.4a652e0eM05m95
Works just as well.
Atrumoris looks like a piece of junk
oh yeah cps we all have DAG 2.2 in the shed tut
Calvin's Tattoo says "let go" maybe zen and the art of bicycle maintenance
Gracias, me ayudó.
Jesus..... I wasnt expecting him to actually beat the shit out of the bike.
How do you align the new shimano derailluers with the bracket axle? Do you just adjust the hanger same as usual or do you adjust it with the bracket axle installed? Thanks
The alignment of the Direct Mount Rear Derailleur hanger is identical to a standard derailleur hanger. This video still applies to those.
Just got the Cyclospirit tool of ebay,same as the park but cheaper,checked all 7 roadbikes and all were out by a lot,should of got this loooong ago,sighting up doesn't work as good as this tool,if u work on ur bikes this should be mandatory tool,also don't think putting a new hanger on doesn't need to be aligned even if u buy a new bike youll be surprised how outta wack a hanger is
And here you are watching a Park Tool video to use it. Shoulda bought a Park and supported them.
@@BluedotProductions Generally you're correct about supporting the tool company (Park) that makes the videos but, if someone is poor, I think Park would be okay about it.
The rock do the job!
My 30-year old Raleigh Cross Sport frame has the rear dropout welded onto the frame. I presume the procedure is the same.
Yes, exactly the same.
what is the part that attaches to the TAP-10 please? The blue handle thing...
That is our Tap Handle the TH-2.
www.parktool.com/product/tap-handle-th-2
is it possible that hanger shifted front back, along the axes of the wheels?
It is possible and not uncommon.
Awesome~!!!!! from korea~~^^::
Do you always have to bash the derailleur with a rock before using the Park Tool DAG-2.2?
We do not always bash the derailleur with a rock before using the DAG-2.2, but when we do, we use a local Jordan Sandstone from the Upper Cambrian.
Thanks!
