"When to Stop" is probably the most important chapter
Especially for those of us with clinical OCD.
Yet new wheels look 100% true (at least some of them)... maybe that's not possible once they have been used with bumps in the rim.
Quality of those tutorials is world class truly.
Thanks!
The quality of these tutorial by Park Tool is world class, second to none.
Park Tools provide some of the best instructional videos in the world, on any platform. They’re models of clarity and concision. Massive congrats to Calvin and the entire team. They create brand loyalty by creating superb content. When I need some bike maintenance kit, even if it costs a little bit extra, I buy Park Tools kit as a ‘thank you’.
These videos are so well done. I learn so much from watching them. I am able to work on my bikes myself. I previously learned from Park Tool vids how to adjust my front and rear derailleurs, which was immensely helpful and rewarding. Having this know-how is more than about saving money from taking my bikes to a shop, it's very satisfying to be able to it myself, and gives me a sense of control. I can't thank Park Tool enough.
This guy is the Bike God himself :DD
When I first saw the Destressing title frame at 10:44 I thought you meant going for a ride after the stress of doing all that detailed work 😄
I have never been much of a comic book reader.
But, if we need a super hero, Mr. Jones would be a good one.
This guy knows his stuff and loves teaching bike maintenance. I have gotten help from him at an event and attended a couple demonstrations, he is such a class act. Bet his blood runs Park Tool blue,
Thank you Mr. Jones!
Absolutely excellent tutorial series. It is so nice to see the normal measuring system used in an English speaking video. Triple thumbs up!

The Gold Standard of cycle maintance videos - clear explanations and excellent graphics & photography - and all for free. Awesome!! A Big Thank-You. Love the spoke squeeze tip at 6:26 :-)
The first and best tutorial I’ve ever watched,
Park Tool knows me sooo well! I just laterally trued my wheel (I’ve tried to aim for perfection in the past and turned a 10 minute job in to 6 hours so have learned to live with 0.2-0.5mm) last night but have been very concerned about a high spot and how to correct this without putting it back out of whack! Now I know how to sort it!
I truly love those videos SO much - thanks to youtube I can do things I never could have done before. Thanks for your effort and time!
Thank,s guy,s. Just refreshing from your older vids.
This is incredibly helpful, thank you so much.
You're very welcome!
Nice and clear voice, easy to understand
Excellent tutorial.
Glad you liked it!
Just the best info, so comprehensive. Many thanks.
Excellent video. I wish my LBS would watch it so they'd stop showing me my radial issues and actually fix them.
Great and informative video. Thank you Park Tool.
Excellent video. Well explained.
Very impressed with the videos from Park Tool. They are so well done!
Awasome, everything visible and complete tutorial THX 🙏
These are excellent videos! Thanks!
Wonderful video. Thank you
These videos are exceptionally good tutorials. I am looking forward to applying the principles soon to true my wheel that is rubbing on the brake on each revolution and I need to replace a spoke on my other bike and tension it.
I always was afraid of radial truing. With this guide - not anymore!
I love this man, so much to learn
Great videos. Thank you. I learned a lot.
Great video--thanks.
thank you, sir! you save my day.
Ну наконец очень нужное видел сняли..Прям хорошо показали и объяснили..You're the best men). Nice video
amazing
very useful video
Thank you so much for demystifying and explaining this process carefully. I would never have thought I'd be able to do this before the pandemic.
Excellent
How do I correct a low spot isolated by one spoke when the spoke is already too loose? Great detail oriented and informative video.
What you describe is a symptom of a bent rim. If the metal hoop has been struck, and a section pushed inward, you get a low spot. Remove the tire and inspect the rim in this area. If it is a minor low spot and just one spoke is involved it does not make the rim un-rideable. If you can feel the low spot as you ride, replace the rim.
@@parktool Makes sense. The rim is true under 1mm except the low spot where is about 2mm. I don't feel it when riding. I can live with it, thanks for the reply, much appreciated.
Thank you
Thanks a lot
this dude looks like zappa! 🙌
Who else is watching this within the first 30 hours of it being posted! We are the truest!!!
How to differentiate a large low spot from a high spot when you have a big section of it, say, half a wheel? Is it that section that is high or the other opposite half that is actually low? I am having a hard time doing that...
If it is half a wheel I would say that one side is high and one side is low and equilizing the two is going to be the solution. You can do this by tightening the high spot then slightly loosening the low spot then tightening the high spot and going back and forth being sure to maintain spoke tension and trueness through the process.
@@parktool thanks so much my friends!
This man is the most gangster I've ever seen im fuckin impressed
First step In doing something correctly is having the correct tools and knowing how to use them. I guess I need a trueing stand now. One of my biggest pet peeves is an untrue wheel. Drive me insane!
Should i cut spokes when truing to balance the wheel?
Question. For the high spots, the video indicates tightening 1/2 turn to start with. Direction arrow is counter clockwise and consistent with tightening arrow on radial videos. For low spots we’re directed to loosen, but why is directional arrow also counterclockwise? Shouldn’t it be opposite of high spots?
Ok what if the spokes are overtightened in those spots where we need to tighten to correct radial truing :(
When do you just accept the the wheel is bent or damaged beyond being able to take out the high spots ?
now I'm glad I got mag alloy wheels.
This is so insanely hard to get within 1mm. Especially so because it throws the lateral off. This is insanely hard because it is difficult to tell if it's a high or low spot, or If the rim is even perfectly round
thanks a lot for your video, they are the best by far i found!
i just want fixe one mistake in this at 8:20 . the rotation on the picture is wrong! i begun to be confused like "oh no, i didn't understand anything at how the spokes work" ^^
Thanks for this catch. Too bad youtubes cannot be edited for this stuff. The action is correct, but the image is wrong.
I have i wheel, that 1/2 is High Spot, other 1/2 is Low Spot. And thats with small tension.
Great video !!! Still confused about small aspect ... so if I do proper later and radial small increment truing I technically don't need to actually measure each individual spoke for tension? If and when, when I am actually checking the actual tension measurement? Thanks in advance.
Take a measurement of maybe 10 spokes, to get an average. In many cases you don't need everyone. Measure after other corrections are made.
I have couple of doubt :
1) Is truing double walled rim the same?
2) Can we even true the double wall rim?
3) Is there a any special care or precaution that should be taken whilst truing double walled rims?
Thanks in advance 🙌
All the rims in this video are double walled rims. So, it is the same, you can true them and there are no special precautions.
What if high spot on tight spokes?
it’s a 1 1/2 for the upper bearing is there anyway to convert that to a 1 1/8?
www.mcmaster.com/bearings/ball-bearings/
weird question but is it possible to convert a future shock 1.5 to a normal 1 1/8 fork. Can I get a adapter for my future shock fork because the steer tube hight is short and also wider than 1 1/8? Can I get a adapter so I can fit a normal 1 1/8 in fork?
you probably could if you get bearings that fit well enough
@@vdel7418 true. I’m almost considering buying a new frame just because the future shock literally adds a pound to my bike and I definitely don’t need it. Haha
Do you destress after each true exercise (lateral, radial, centering) or after all three?
Simply de-stress after you are compete, as the last step. Spin one more time to see nothing significant has changed, and your done.
Perfect. Thanks!
Can a bad wheel cause the disc brake to cling on the caliper?
Unlikely in the extreme.
what if lateral is true, but the low spot spokes are too loose. I have the tm-1 tool, and the other spokes are within spec. Newer wheels that haven't seen a big bump. I'm lost.
Numbers (typically) don't lie. It might not have hit a bump, but it possible it was manufactured with a slight deformity. Pull up tension if you can everywhere else but do not tighten that low spot.
Thank you@@parktool
can radial truing be done with the tire on?
Yes, but it is more difficult to see the low and high areas.
I want to buy this tool
Me too. I've had some success truing wheels in the frame, but this would be a lot easier I think.
What do you guys recommend when half the wheel could be a high spot or half could be a low spot? Im building a wheel and it's like playing whackamole!
Yes, sort of. Consider you are moving high spots and low spots around until it is adequately round.
@@parktool i got it to 1 mm. Now i fix the lateral true again. And then I'm onto to tension balancing with the TM-1. These spokes are 166 mm its hard to Guage by feel alone
I can't seem to get rid of a tiny bump around the area where the rim is fused together. (I don't mean a burr but an actual height increase) I could increase spoke tension in that area but then one spoke would exceed the maximum recommended spoke tension for the rim as specified by the manufacturer. I wonder if it is common to have a "tricky spot" in the area where the rim ends are fused? (The difference is less than a mm but still very visible)
Where the rim is jointed together you will typically have a deviation that you may not be able to adjust out.
@@parktool Thanks for the reply! Both my new rims indeed seem to have this.
Does anything change substantially with carbon rims? I've heard they mostly either come true out of the factory, or they'll never be true (especially with deep section rims). This is probably an oversimplification, but maybe you can provide some insight.
If it is a well built rim, carbon fiber is very easy and pull up quickly. They are very rigid and stay true a long time. If poorly build, they are hard to get straight for the same reasons.
Do cheaper wheels untrue faster? I feel like Im always tightening loose spokes
Typically less expensive wheels have a weaker rim and will go out of true quicker. But just because a wheel is more expensive does not mean it will automatically be stronger. Weight, strength, aerodynamics, width and visual appeal are all reasons someone may spend more on a wheel. So just because it costs more does not always mean it will be stronger.
1mm…..keep very precise for true wheel!!
Kusheen was here...
7:18 that spike calipers seems like scratched the rims and could damaging the rim also
The tip of the calipers have optional plastic tips. Some people prefer the metal on metal for the more audible sound. This is especially nice on rim brake rims. They will be scratched anyway.
8:52 Halt 😂😂😂
8:20 losen right or left
Thank you for providing the tolerance of 1mm is used. However an explanation of how to radially true the rim would make the video more useful.
video starts at 4:03 dont thank me
Am I really this early
Still not convinced about your destressing advice. Just put the trued wheel on the carpet, push all sides, put it on one side and push the rim, other side and push the rim...
Next, put it in the truing stand and you will immediately see the wheel has to have some truing corrections. Don't just ride it, it slows down the whole process (mounting the tire, riding, demounting, truing,...)...
radrunner got a flat spot....needs puller.... The spoke wrench did absolutely nothing for it
With a flat spot like that you are best to get a new wheel or have a new rim laced to your current hub.

Hey I actually got the second comment on a video for once
Content is good but the noise in the background (guitar bloat?) when explaining stuff ruins the whole video - really sucks.
Omgggggg.... how many times are you going to define what a wheel is, what a spoke is, how it works together, what tools you need. “Video 78, this is a wheel, a wheel truing stand is used to true a wheel. Spoke create tension”..... fukkkk we know!!!’ On with the details!!!! Slowest video ever. You’re getting all of my down votes!
This is top notch educational tricks of the trade with no bullshit virtual classroom right here. Well done👏!!🚵🚴🚲🦽🏁
