try removing that cassette when you have a rusty 2 year old back wheel and you dont have a stable vice . gonna have to take it to a a local bike mechanic

This was less crucial in my case than the rear derailleur but there was a little noise and misalignment and this video was equally helpful. I can now ride my bike without the risk of being eaten by barn owls. Thanks!

Very detailed explanation on the different possible situations that might be encountered when changing the tyres. Thanks!

Never realised that my dual pivot calipers just needed approximate centring before fine-tuning with separate adjustment, thanks

Hello, Is that a Aluminum Freehub protector or Metal? where can we buy this item?

My old pads were really thin, I got new ones and they are to thick so my rotor doesn't fit in and iv pushed the pads back what do I do?

I'm 6'10 I ride an old school early 80's 68cm Japanese road bike chrome moly frame with Suntour superbe friction derailleurs and Suntour Barcons on the ends of my drop handlebars. It's fun and works for my length. I don't have to spend $3000+ having a bike specially made.

Corrention:Original rim.

Where i can buy original parts of a road bike like ream.

he is explaining it well but im so confused.

Hi, I'm Joëlle, bicycle mechanic and trainer at the CyCLO DIY workshop in Brussels. A few days ago, I passed a qualification exam of wheelbuilding. The wheel fulfilled almost all of the jury's requirements. I obtained 95%, because a wheel can never be perfect ;-) Dear Calvin and Truman, THANK YOU very much for the great videos! Always very instructive and nice to watch. Let's keep learning👩‍🔧

the background music is a little distracting, maybe choose something more subtle

you missed the opportunity to say "cranks for watching"

Thank you truly!

How is this video 3 hours 😂

I havent got that bike stand and I feel like my back will need an adjusting by the chiropractor tomorrow....

You're the best Calvin ! I met you YEARS ago as a student when you were teaching at the John Barnett Bicycle Institute . . . Cheers from Montreal ! :-)

I got lost at 3rd set and sent my wheel to the bicycle shop. So confusing!!

This is incredibly useful. Thank you!

Ty so much.

Only halfway through my indexing was right and noise on all gears removed. This was an excellent video for novice bike maintenance guys like me! Thanks!

So many factors 😳

Amazing video. Top quality. I'm without words.

Park Tool is one of those very rare companies that actually respects consumers and its customers. Truly one of the last great brands out there.

brilliant! simply brilliant.

I'm just wondering why your subscribers is not increasing,it is still 830 k

8:12 I have same problem, but when i hit the tube in bb shell the tube is damaged..what should i do to remove t bb shell?

10:13 yesterday I worked on my bike until 4:00 AM, so I have a new saying ... "If is broke, don't fix it" 🤷‍♂

Been fighting my bikes for hours and this video helped me to understand the mechanics of these bikes…thanks Frank Zappa!🎸

Hi. Which spirit level app do you use?

It would have been good if you had said exactly which way you were turning to loosen, rather than just saying, "Use a 3/8 drive ratchet or breaker bar to drive the tool", There's only one tool that I can see & hear! I'll try a better and more informative RU-vid video.

Now I understand how to correctly centre the brake pads on the rim, awesome 😁

Very good video and clear step by step guidance...... Thank you sir!

Oh h yes

0:51 I didn't get that part (which is most important), screw must be grinding against the frame ?

awesome ! thanks !

Can deore m615 rd fit to 46t cogs thanks

I’m tired grandpa 😓

Im having trouble in doing 3rd set. The spoke couldnt reach the rim hole after passing 3 spokes. Help me

Thank you so much 🙏

Best tutorial

You are my favourite Park Tool host!

What tool do you use to check pitting on the spindle?

3:23 this screw moves extremly hard when I took the deraileur off, what could cause that ? I tried all kind of sprays and oil on it, in the end I thought it was supposed to turn that hard.

Update: I will be trying to reinstall a front derailleur later this week. Took it to a shop to get quote and was quoted $45 to install and $95 an hour for labor. I said nope. Guess need to master this video. If I’m to replace both front and rear shifters/cables and both front and rear derailleurs. What should be done first so I can finally get the derailleur into adjusting? Since I fallen quite a dozen times and 2-3x were at speeds of 20-28 mph. Pretty sure all of it has to be fixed as my gear covers were damaged.

Awesome video, I was able to true my wheel for my first time, in less than an hour 👏🏿👏🏿..thank you

What if the nipple was aluminum, then magnets wouldn’t work?

You didn’t say anything

Just found your RU-vid. I bought a book from you 14 years ago. Your book help me through so many bike repairs because I rode my bike everywhere for at least 10 plus years. 14 miles a day and more. Thanks bro it’s like seeing an old friend!
