Calvin is like the🔧Dumbledore of bike mechanic wizardry ⚡️
This man is born to make these kind of videos 🙂. Thanks a lot!
I have to mention that before doing ANY derailleur alignment, you should ALWAYS CHECK YOUR AXLE, HUB, driver/freewhub and Cassette for torque, alignment and function.
Many customers over the years w shifting issues caused by a misaligned qr axle, bad hub, bent teeth/chain.
My wife thinks I'm crazy watching bike repair videos each night in bed. Therapeutic. Nice video, Calvin.
First place bike video repairs
Second place wife.😂😂💪💪
I think it's the difficulty of balancing the keyboard on her lower hips.
It's very relaxing and takes your mind off the world collapsing. I can relate.
repair videos for the win
So I catch the video a week after using that tool to align a steel dropout and it worked brilliantly. Another decade for my 2 x 9. I used a marker to mark the spots. What's good about Calvin is he can explain it without sounding pissed off, like I would.
The problem was that the owner added a direct mount D-Link to the hanger, then attaching the derailleur to the D-Link caused the derailleur's chainline to be moved out by the thickness of the D-Link. Which is why the limit screws were totally wound out, as the derailleur can hardly reach the largest cog with the increment in chainline.
Another component you can consider if you want to use a larger cassette than recommended, is a derailleur hanger extension. It's an add-on to the derailleur hanger, and does not replace the original D-Link of the derailleur, while keeping the chainline similar.
😁 i was going to write such straight explanation as well as I felt it was blatantly omitted in the video... but you were here first, nice! 👍
As a newbie to working on bikes this is great info. I wanted to add a larger cassette on a bike I just bought for my wife but I have no idea where to find the info on how big of a final cog I can use on a Deore XT drivetrain. I just have no idea what to search for but maybe all I need is a hanger extension.
@@Iosis6 A derailleur hanger extension will work well, albeit not officially recommended. There are tons of cheap ones online, anodized to your favourite colour! Or else, other famed component brands do carry them too (WolfTooth). Good luck!!! :)
@@zoladkow hahaha, Calvin and Park Tool are legends, they are trying to help us circumvent common mistakes especially with this D-Link thingy. If it were me, I'll probably take weeks before I realise what's wrong with this bike. Mad props to Calvin!
What is the derailleur hanger extension? Can you link brand of product? Thank you
Great host, communicates so well. I don't watch em all, but this guy... 👌👌
I have learned so much from all Park Tool videos, thank you so much, definitely my to go videos.
Another great video! Looks like the bike had "hangar management" issues.
Underappreciated comment 👍
Why Hangar? Isn't it Hanger?
Damn he totally missed the opportunity to say "When the limit screws are at the extreme, it's time to look in-between... the derailleur and hanger"
Shout out to Wolf Tooth Components for making quality parts that make our granny gear bigger and our bikes sexier. 😎
NICE explanations Calvin. I appreciate the knowledge you share. Another one in the books :- )
Bike doctor, who I will always go to for any of my bike technical knowledge. 👍🏻💪🏻
beeen working on bikes tor 50 years but you are the mann dont stop dont change
Thank you Calvin and Park Tool for another informative video. I was wondering if you can also make RD shifter disassembly and maintenance video specific XT M8100 and XTR shifter more power to your awesome channel 💯👍💯
If it’s an existing mech & cassette…. Check chain length and Hanger alignment for sure.
I spent a lot of time trying to correct a setup that either couldn’t change correctly in high gears, or if adjusted, low gears…..
Great content as always, from the makers of the finest tools to fettle your bike.
Thanks for sharing your knowledge!
This man is a genius
Buen video , muy bien explicado y muy util. Enhorabuena !!!!!
Thanks you! I just needed to check it out
Love Calvin. He's amazing.
You’re a genius Gump , absolute genius
When I set up a derailleur for a mates bike I do the stops first so the chain don’t go into the wheel or in the frame 👍 🚲💨
Calvin reminds me of Mr. Rogers. So smart and wholesome.
Thank you 😊 Looks like I set up my extra link correctly first time.
Awesome as per usual
If only we could have Calvin check our bikes and have them adjusted correctly.
Very interesting sir. Thanks for sharing this with us.
"The manufacturer's literature". In other words: RTFM.
Read the fisherman manual?
Is that included in shimano fishing rods?
TL;DR RFL
Thank you. I learned a lot.
He is the Bob Ross of bicycles
Thank you for the informative video
I’ve done this to a friend’s bike when we were doing a drop bar brifter to wide range 1x11 mullet. 😬 Fixed it in the end but who knew Goat Links are different than Road Links. 😆
Bonjour Calvin , C'est très intéressant 👍 Thank you 😊
Always learn something new 👍
Calvin, every new bike I’ve ever bought had the derailleur hanger out of alignment enough to need correction. Also, the last bike I bought, a Cannondale Topstone 105SE (first edition), had a chain one link too long. To compensate, they had the D screw run almost all the way in to compensate, and the upper jockey wheel was way too far down and back from the cassette. There’s even a few pictures on the net of it although they must of corrected it during the model run because not all were that way.
So true! My current bike was my first bike not from an LBS, instead it came in a box. I was sure that if my LBS couldn't get it right what were the odds that, even if they had set it up properly before shipping, that it would survive in said condition: I was absolutely shocked that this would be my first bike ever where the limits were set correctly, alignment was good, only my rear brake was rubbing ever so slightly.
Extra parts, how you know you did the job right. 👍
Calvin, thank you very match!!
I promise you I wish you released this video 6 months ago.
Broke a hanger after running my bike for months in the wrong way. Recently got new hanger and extender fitted it correctly and it's been perfect ever since
Wow the amount I've learned in 9 months haha
Good oh. Also looks like the chain is a link or so too short.
I bought myself a DAG-3, because my old DAG-1 wouldn't sit next to some modern carbon frames. However, I'm a bit worried that the plastic bit will one day wear and get sloppy, and the O-rings on the feeler rod perish and drop off, and so I'll lose the feeler. I started out thinking that the feeler rod mount and pivot were on the wrong side of the bar, as I do all my hanger aligning standing up behind the bike, but I've got used to it now (you could swap the feeler rod mount to whichever side you wanted on the DAG-1 & 2)
nah chain looks good its a hardtail
Calvin is the best!
Awesome I was just about to change my cassette I needed to used the same link extender was going to put it on with to meny link lol thanks
Great video, have seen may bike with a link too far
new camera? video quality looks awesome
Thank you. I had the same issue. Found out my hanger was off
The end of the cable and the ferrule were catching the spokes!
Calvin... Do not die... ever!!
Love me some Calvin
When Calvin talks, the world listens.
Cut that cable down after the cable anchor bolt!
Nice video!....But seriously, an extra link?...WHO does that?!😁
Bro's thinking they can cheap their way to a "bigger than your" cog and don't put in the riding hours, so I still blast by them on my SS.
I've tell my guys this a long time ago, when you this replacement b-link beginning exist in my country's FB groups community that you should replace instead of add them.... They're too ignorant to accept this fact, they're too proud to use those gigantic sprocket even though their system isn't compatible
chain looks a little too short for a low gear that big. That derailer is SCREAMING trying to bend back like that.
I’m surprised you can even put the links together like that, aside from how did they did not know this
Great Job.. Question- What long cage Shimano mountain bike derailleur works with Shimano Claris 8 speed road shifters?
All of them. The pull ratios are identical until up to 10 speed.
If there’s a bike part that doesn’t have an appropriate Park tool, I don’t know what it is….
(but I’m still getting the hang of hydraulic brakes 🤪)
Spoke threader.
Almost anything related to Hope components. Except brake bleeding, but a lot of their stuff uses proprietary tools.
Can deore m615 rd fit to 46t cogs thanks
"And how do we know this? We read the manual"
Many things in life are actually really simple... :)
I'm surprised Calvin hasn't been picked up by the discovery channel, or animal planet or something like that... he can talk about grass slowly growing and I'd be listening closely to every word. lol
think he needs a couple links in his chain that deraillure looked pretty stretched out.
Got to ask, did you set this up for the purpose of the video?
Because i cant unserstand how someone would buy a hanger extension but just add it and not replace.
We have seen this several times in the wild.
@@parktool that's mad to me why would someone do enough research to know they need an extension but not know to replace haha.
While I have your attention. I have just done maintenance on my sons bike, I cleaned out the cup and cone as someone spilled concrete powder on it.
Anyway my question is when I reassembled the wheel would tighten the bearing when the wheel rolled. What on earth did I do wrong to make that happen.... if you could help that would be awesome.
What would I do to know even a fraction of what he knows about bike wrenching...
Study?
What type of tool did you use to remove derailleur ?
That is the QTH-1.
don't know how the bike owner didn't notice that, either way we'll diagnosed and corrected kelvin
RTFM!
what tool are you using to remove the Derailleur ?
5mm allenwrench
@@jmvillavicencio3449 ty I’m aware of the size required just hadn’t seen that specific park tool.
@@bob8fred ok correct me if I'm wrong that's the atd-1 ??
@@jmvillavicencio3449 QTH-1
Why did shimano do this? Why not just go straight to the hanger?
Or here's a idea use a rear derailleur that is designed to run a 46 tooth big gear that looks like a Shimano tourney the max they can go up to is 34 teeth even my Shimano acera has a 34 tooth limit
I think it's old Deore 10 speed which is 42 tooth limit.
New/replacement RD can be very expensive, especially if a long cage is required to accommodate a bigger cassette. I know, I have spent a few hundred dollars doing so... and the RD hanger extender is less than $20 and works very well in my experience
went with à Wolftooth to go from à 34 to à 42 while keeping my midrange dérailleur. worked fine all the way across us
Can i use a 10 speed rd to a 9 speed sprocket 42t? With a link?
Depends.... the issue is if your shifter's throw ratio can shift through the 9 cogs fine. It's a crap shoot on which brand and model will be compatible with your particular 10sp derailleur. My suggestion is to just try it. Your derailleur actually could care less how many speeds you are running, it's the shifter that decides how many clicks and how far to pull the cable (pull ratio). As for adding a link, if the derailleur's B screw isn't maxxed in and you've added enough chain links then you're fine, if not, than you need an extender or dlink.
...actually it's okay if the B screw is maxxed in. As long as you're jockey wheel is clearing the biggest cog (your new 42t). If the maxxed in B screw can't allow the jockey wheel to clear the 42t cog, for sure you need an extender or dlink.
There are a lot of variables here but the most accurate answer is going to be "no".
1 by is by far the dumbest "revolution" in mtb. So glad I have no cross chain problems, don't need a rear derailler with clutch, don't need an oversized, overprized and overweight cassette, don't need a chainguide and also, can shift in a second from full descent mode to full climbing mode.
Otherwise a rather nice bike
1:27 With the chain in the second to the largest cog, I'd just carefully bend the RD hanger a bit inward until the chain jumps to the largest cog. : )
Which may solve the problem but at the same time causing new problem at the smallest and second smallest cogs
Should you never use two links?
There are derailleur hanger extenders OR, as in this video, an after market dlink that is meant to replace the original dlink. I'm guessing the owner of the bike didn't realized he had the latter. Weird that he got the correct part but didn't install it properly. Most people would order an extender not knowing they need a longer dlink.
@@newttella1043 Thanks
cocaine is a powerful drug, that bike should be deemed a death trap.
“more better”. Another Calvin-ism…
555th 👍 Sweet
Am I the only one or is the chain too short for this setup?
Chain length was good. That is a huge range to cover from the smallest to largest. Any longer it would sag at the other end.
@@parktool Thank you and be well!
The problem is they were using the wolfs tooth to make the derailleur work with that large cassette, when most likely the derailleur is not rated for that much difference in tooth range. So the chains looks too short but in this case will have to be okay but in a properly designed native system with the matching cassette and derailleur, this would look like a too short chain scenario.
TLDR: RTFM
Sure would be better without the silly, distracting background music.
you must be fun at parties
@@MisterRabbiit He's always "Boron" and is okay with it.
Remove the link between your products and China LOL
Annoying and distracting music. Who thought this was a good idea??
