This Seth guy should have his own channel, mark my words, this kids going places.
Consider them marked
These videos are like WebMd for me. Every time I watch one, I feel like my bike has cancer.
hahahaha yes. Stage 4 terminal
I have a derailleur hanger alignment tool and I think it's an absolute essential for any serious mtbr!
Tomi Saaranen self promoting again😒
@@Cleanmusiccuts Lmao how is that self promoting?
Digging and Riding all he’s doing is commenting. If you wanna see a self promoter check out lakeside launchers.
It's an kind of an "inside joke"
Just have some replacement hangars
Never knew these alignment tools existed. The amount of hangers that have just been thrown out lol
Cool, so I should check my hanger first before doing any adjustments to my derailleur?
At the very least a visual inspection of the alignment should happen prior to adjusting.
Great video! I allways check my new hangers for misalignment. More often than not, they need a little bit of care.
What if the wheel
Is bend? Shouldnt you turn the wheel
Together with the tool? Measure at the valve at the bottom and then at the top?
Yes very good
seth runs carbon rims, they don't bend they snap
@@engineergaming2553 that was not the question
you should probably true the wheel first.
@@greensphinx aint nobody got time for that son
seems like it's a must to make sure you are referring this to a wheel that is spot on true.
Simply move the rim with the tool. As an example, use the rim at the valve, and check at the various points.
Should ypu pick a single point on the rim and rotate the wheel with the tool to account for the wheel being out of true or is this over complicating?
Yes, that is how the instructions say to do it, and what makes sense. However if the horizontal run out is within a couple MMs (and you verify this), it's not a huge deal.
@@cup_and_cone I made this a while back for singletracks.com and was double guessing myself th-cam.com/video/edNG3pUf5HQ/w-d-xo.html
The height difference of Seth and Calvin is very large.
i dont know if seth is smol or calvin is rly tall
Seth is 5' 5" and Calvin is probably like six feet
Daniel Weinacht Seth’s 5’4” and I think calvins like 6’3”
Gandalf and Frodo
Fistly I have one of these tools and it very good for the job. I also follow the valve round.
Another approach could to buy yourself a new derailleur hanger they sre quick and easy to fit. Also check that the hanger is tight.......I've come across a few loose ones, even on new bikes!!!
These tools are pretty much necessary now. It's crazy how many new bikes I've assembled out of the box that have a bent hanger from shipping!
These are good tune ups. Thank you!
The information and entertainment value in these videos is through the roof!
Thanks, Guys!
Seth & Calvin in the same vid. Mtb royalty!!
Bracing technique. Another pro tip.
very disappointed that he did not use the tool properly. When you rotate the tool you should also be rotating the wheel and checking at the same location on the rim. This takes out any truing issues of the rim. Yes we hope that Seth's wheels are true but its all in the details.
I totally agree! If you are going to teach, teach it right. The video still shows what the tool does and how important it is. Only 1 thumb vice 2 up.
@@fireball9709 yep he showed the quick and dirty of it. Also kinda showed that you should be checking more than just 12 & 6 but also 3 & 9.
@@cliffjones1061 3 and 9 is more critical than ever now that we have wide ranger cassettes. The pulley wheels are more prone to being horizontal now because of the range, which makes 3 and 9 just as important.
@@cup_and_cone 100% agree. I'm a bit Obsessive with my bike so I start with 12 & 6 then do 3 & 9 and keep going from there in the end I go for a 1mm tolerance just like when I build wheels. Can a shop mechanic make money going to that level on an average tune up, no. But This is my bike and my time so I can go nutz if i want to.
Agreed, but at least the mentioned (although not linked?) video for hanger alignment covers all these details and explains the whole process. It's really good!
Hi Parktool, thanks for the video and my ongoing education on bike maintenance :) Could you please link to the mentioned video and correct the used tools (link them too) in the video description?
Kudos to you from Germany, Toshi
Very cool....been thinking of getting one.
Reason #238 to stick with 9 speed and friction-capable shifters :)
There are too many tools i need. Been borrowing from a friend but that has come to a end. I need to start collecting tools. Not as fun as purchasing upgrade parts lol.
@@aanthony2025 Agree. That's my exact intentions 👍
Great video but isn't a new derailleur hanger cheaper than the tool?
Good question. First, it can take quite a bit of time to even locate the right hanger. There are literally hundreds of models and styles. But even a new and well-made hanger can need checking. The frame interface with the hanger is often less than perfect, so you are aligning the new hanger to the specific frame.
Hangers for my bike are around 30€, and the tool's around 80. So it eventually pays for itself.
I go to the valve in case the wheel isn’t true
I just hope his wheel was true, I was taught to rotate the alignment gauge AND the wheel in order to factor possible defects in the wheel itself.
Seth's wheel, having a wobble? Straight as can be, but your comment is true, as they say. The rim run out (wobble) is typically from spoke tension issues or simply smashing something.
hi I've been working on a kids bike with a one piece crank and to times now the nuts that hold the bearings in have come loose and the bearings come out of the ring that holds them together do you know what may fix this problem
When threaded parts, like nuts, come loose, it is most likely they were not fully tight. It is difficult to get a torque wrench on the parts, but when holding a wrench at say 6-inches from the nut, apply at least a 60 pound effort. See also th-cam.com/video/dpl_wlTBC8k/w-d-xo.html
+Park Tool thank you I love your videos they are fun and very entertaining one day I would love to have park tools of my own
i thought you were meant to use a common reference point ( like the valve ) to take wheel trueness out of the equation. Am I misinformed?
The problem I see with this alignment gauge is, your tire needs to be as true as possible. Can't fix a derailleur hanger with a tire that's heavily bent. So what's the max. tolerance here?
Spin wheel together with tool. Always measure from same spot on wheel, use valve as guide.
I was in a trial at 6:00 and my derailleur hanger completely bent in so I had to align it with no tools then I went to pedal up a hill and it cracked off
What if the wheel is out of true?
then you rotate the wheel after you have set the pin, and check the same spot on the wheel but when it is rotated
Nice...
Why don't you use the tire valve as a reference for the alignment ? if the rim is crooked the alignment of the derailleur hanger will be crooked.
This rim was very straight, but when not use the valve as you say.
The wheel has to be trued for this right?
If you follow the vavle stem and reference that same spot the whole way around then the trueness of the wheel does not matter.
Hi 👋
can calvin fix the shifting on the murder machine :D
I don't get it. How could my GX 11 speed shift perfectly on one day, then struggle dropping off to the next smallest cog the next day? Driving me crazy!!
How much is that tool
Pricing is dependent on where you are located. In Chile, our products are distributed by Belda Cycles. A full list of our worldwide distributors can be found on our website: www.parktool.com/trade-resources/worldwide-distributors
you better make sure your wheel is straight before using that gauge then
Not necessary, because you should use the same part of the rim for measuring each position (was not shown in this video). I like using the valve stem just because it's easy to remember. Rotate the wheel with you as you move the DAG around.
@@cup_and_cone that makes much more sense
Personaly i use m'y Bear hand :')
Park tool is cool tech Tuesday is cool. Seth's bike hacks is just okay.
I feel the opposite. I generally like the park tool videos, and I rely on them as an instruction set of sorts for their tools. I feel like they are leveraging Seth's popularity and his 1 million + subscribers to boost Park's exposure. I just wish the Park side of the videos wasn't so "watered down" ... and I'm trying to be nice here. Seth knows how to build and fix a bike, but here they make it look like they need to show him how to push the tool just right like he is learning something. Seth even got interrupted twice when he tries to talk. In the last installment two park guys were hitting things with a hammer in some "don't do this at home" hack. Then they argued with the commentators and deleted their comments even though anyone who watches Tech Tuesday knows they know better. Hopefully the guest appearances are over and both channels can go back to normal.
@@adaycj I see where you are coming from I just don't add big explanation they did seem to dumb down both TH-camrs. - Utah Rider.
@@angelocordero5661 I'm not known for having few words ... ride on.
We don't care about your position on the leaderboard of comment speed
First to reply
oh no
@@daylightsensor8695 lmao
Seth gone clippers?
I don't have this great tool, but I had a something about 1x3 inch and almost one meter long piece of wood; 3 Wood screws; Bicycle rear axle. And also a vernier caliper. I got my bike derailleur hanger fairly right with just those.. or right enough for me to ride. Well actually I lie. Those were not all I needed. I also used screwdriver for torx head screws, wood screws had torx heads.. I prefer torx ^_^
Why dose Seth’s bike have clipless pedals
He doesn't except for his road bike.
Or if you think the hanger is bent..just buy a new one, you can buy like 20 hangers for the price of that tool and if you bend that many hangers you might want to rethink the way you ride lol
Most hangers come new needing to be aligned.
Hangers can be $40-50 from the LBS (in Australia). You can buy the updated DAG-3 for $200. Wait for it to come on sale or buy the one on the video for about $120. You also get to feel better about fixing something rather than replacing it.

Oh booi
De s-ar gasi si pe la noi chestii de la Park Tool...
Then u find out your wheel needs to be trued 😂
That was so awkward
I didn’t realise how short Seth was before
Who cares we are here for bike videos
What if your rim is bent? 🤪🤪🤪
Then pick one point, like at the valve, and spin the wheel with the pointer. This creates a flat plane for reference.
@@parktool Didn't expect an answer, it was a joke😅 But still excellent job! I love working on bikes!
It helps if you use the tool correctly, wtf ? Same point on the rim.....FFS.
Ayyy2nd
just buy a new derailleur hanger
New stuff is always nice, but it is often the frame joint that is not square. Replacement hangers tend to be made straight, but it is often the frame that is off. Alignment is then made to the bike being fitted.
@@parktool any thoughts on direct mount derailleurs? is there anything to do here in terms of alignment?
The direct mount hangers are the same thread (10mm x 1mm) and should be checked as well.
