Best video I've ever seen explaining chainwear, and I've been fixing my own bikes, replacing chains, cassettes, and cranksets for over 30 years. Thank you so much for video 😊😊

This video should have been watched by millions of people! Thank You so much SIR!

Excellent explanation! No nonsense, no needless talking, no stupid music, excellent graphics.

That is by far the best video I have ever seen explaining chain-wear. Your graphics are outstanding on this! I know how much time it takes to put a video like this together, with this kind of quality! I just happened to change both my chains on my indoor training bike, and my race bike last week after checking the chain-wear. Amazing what a new chain does for shifting and the noise level on the drivetrain. You video is very much appreciated by a fellow cyclist in Texas!

Best explation I have seen.

Just like to back up what Tower Runner said below - fantastic video with very clear descriptions and graphics. Well done!

GCN pisses me off sometimes when they are doing tutorials on perfect bikes, they often neglect to show what a worn out component looks like. Thanks for this video, really thorough.

I let my last road chain go to far and had to replace the cassette too. Got it done, working, but still had aweful drivetrain noise, and thought my front chainrings needed replacing too. Had a ride in the rain, washed bike, re-oiled chain, and suddenly it was silent! All the noise was apparently due to the storage grease on the chain. Never experienced it like that before, but there you go - I'll be re-oiling my new chains from now on.

You just inspired me to keep a better eye on my chain. I do have a chain checker tool, but I never use it. Such a waste of cassette and chainring :( I just saw a bunch of chain-wear vids but yours is so clear, with the visuals. My chain is even sitting on top of a brand new chainring, so now I know why. Thanks a lot!

Excellent explanation and well selected pictures! To estimate a chain wear one can also use a caliper.

Thank God for this gentleman who explains this important matter so thoroughly and clearly... For free!

Never seen a video that explains this nicely how a chain wear affects your drivetrain. Good job, and thank you!

The best explanation I've ever seen thanks

This is the exact high quality video I was looking for. The amount of work put into it is obvious. Thanks.

The best video on the topic I have seen, thanks for the detailed graphical explanation.

Love your no nonsense videos - thanks

New chain on worn cogs is bad I found that out real quick a few years ago. Great video.

Another great video Steve. Very comprehensive. I always feel like I learned some important stuff from your videos and you don't skimp on the details. Keep up the good work.

Excellent video!! Simple explanation!! I have leanrt so many things today! I was wondering why I didn't have smooth gear changing on my bike! I have found the solution. From now on I will put a new chain every 2000 Khm. Thanks!!

by far the best video ive seen explaining exactly why my bike is knackered lol

I really appreciate your channel. Clear real to the point explanations. Thanks for your effort please keep them coming.

This is absolutely clear, thanks and keep up the good work!

What an excellent, thorough video! Seriously impressed!

Great video! I have found that for me my chains wear about three times as fast as my cassettes. A new chain will wear down very quickly on a worn cassette and vice versa. Usually, the wear of only a few of the most used cogs on the cassette "spoil" the cassette. A trick I have used in the past to extend the life of chains and cassettes is to start with three chains and rotate them on about a 1000km basis. The chain and cassette wear matches up better and reduces the accelerated wear caused by mixing new and worn components. It has doubled to tripled the life of those two components on my commuter bikes. I usually put in about 5000-9000km annually so it can save a bit of cash to purchase other bike bling!

Started this video thinking..he can’t teach me anything. I was so wrong! Great video and best explanation ever! Thanks!

Worth watching every minute of the video. So detailed and comprehensive.

Best overall description and explanation for how to recognize when the chain needs replacing and the impact on chain rings and rear cogs! Thanks!

You are a GREAT teacher! Thank you SO much for sharing your knowledge with us KZfaqrs.

One of the best bike channel I know. Good job!

Still one of the best videos on the subject! TY

Without a shadow the best explanation I've seen & simply exactly what I was looking for! Thank you, Oz mate:)

Absolutely fantastic analysis. Great work.

One of the best explained videos on this topic!

I describe and advise this many times a week to my customers, your explanation is excellent/

👍Good , easy to understand,& amazing illustration, thanks a lot.

Another quality video. Best Explanation by far.

Really informative video! Explains everything about chains and drivetrain so clearly, thanks!

You've just got a sub! This is the most detailed explanation of chain wear ever. Nobody ever mentioned 0.5% wear, everyone sticks to 0.75%. Thank you, I'm going to check out your other videos.

Truly informative. Professional level forensics. Thank you.

Nice job on explaining important stuff regarding chain wear..and not just for dummies...like me.

A very nice and very detailed vid - thank you for all the work.

great, maybe the best video on chain wear! THANKS!

Without a doubt, this is the very best video on chain wear I have ever seen, well done sir

Excellent vídeo! thank you and congratulations! I have learned more than I expected...

Great video, my friend! Last good explanation about this issue I've seen was on Sheldon Brown's forum, but you made an even more detailed one. Greetings from Brazil, you are for sure helping a lot of cyclists here!

Very well illustrated and explained, thank you mate!

Super video. Answered all my questions clearly and accurately.

Excellent video, Steve!

A complete and comprehensive explanation regarding chain wear and tear...

Really nicely made video. Good work, my friend. I can vouch for the Park Tool chain checker. Great value.

Excellent video, really well explained. A chain wear tool is a well worth buying.

Greetings from California! Excellent video " mate" thanks for the knowledge! Keep up this great service which you are doing- educating the next generation of cyclists.

Hello OZ and thank you for this very useful video. You really elaborated it to the smallest details 👍

Very well explained and illustrated - excellent. Thanks

Probably the most imformation on any bike video I’ve seen well done.

Fantastic overview, and love the graphics!

High Quality Content. Thanks for sharing ❤

Learnt more about the chain and wear today. Thanks for your help.

Remember to check several different sections of the chain. They do Not wear evenly in all links. Probably due to slight manufacturing tolerance

Outstanding clarity, thank you.

Excellent video, I’ve actually just replaced a SRAM Red chain after 1400 miles, it showed .25% at 1000miles then rapidly went to .5%. Interestingly it didn’t measure the same wear right around the chain, some places were slightly better than others. So worth checking in 2-3 places.

now that was well done ,fully explains what's going on all around and now we know what to look for even without the tool

Clear explanation, thank you !

Another informative video.. thanks mate

Top stuff just getting spares for all good to know when to do all this and how . Thank you m8 !

finally i understand what the 1.0 and 0.75 stands for on my chain measure tool.... lol! thanks! and reallly loves your videos!

Hmm.. I think this vid was a little bit more than helpful... It explained in full detail just what happens to our drive systems .. I'd say it was more like... Amazing!..Thanks for taking the time and doing this for all who ride...

Great video, probably best explanation on KZfaq. Thank you!

I cant honestly fathom why someone gives this a dislike, its a brilliant explaination on the matter

Thank you for this! Very informative and easy to understand

Cheers mate , good imfo, just overhauling my road bike now. Saved me a lot of pain.😁

I get good results from running two chains. I swap them out every month or so and they get a thorough clean and relube. Thanks for the very informative video.

Brilliant video, very well explained! Thanks so much

best chain wear explanation ever

Outstanding.... I'm so impressed. Very well done 👍 Subscribed

I have jus learnt why my chain was acting up. Perfect tutorial, now my chain ring & chain will have to be changed. Checked cassette, that's fine. Again best tutorial, easy to follow. 👍

Awesome video. A lot of useful information. Thanks a lot.

Thanks for this video from Spain.

Much appreciate showing the tape measure check. Thanks.

Outstanding Oz! My bike is hurting for sure. Front rings are sharp and a few chipped off. Rear cassette looks good I think. It was a free used bike and I don't know the history. It has got me peddling again though, which I am very grateful for. Cheers from California.

Truly Awesome Video. Well done, and thank you!

Excellent video. I learned a lot. Thanks!

Thank you so much this is very helpful information. I wish I have watched this video long ago...

Very good video the best explanation on utube on that note i just got my 105 shifters 5 minutes ago im now going to watch your video on how to install them on my 60 inch tv 5 feet away from my bike so i dont miss anything lol.

Best video I have seen any wear (get it 😂) on the net. Seriously, awesome explanation.

best video i've seen re chain-wear, front/rear cogs... thanks

Brilliant Mate, really useful.

Great video! I have to buy a new tool to measure the wear of my chain! Many thanks.

Good, clear advice. Thank you!

This is top-notch content. Thank you. I just subscribed.

Excellent!

I just replaced my chain after two years. It was riding up on on the teeth and occasionally jumping under hard pedaling. The chain was about 1/2 inch stretched overall!

Excellent. Love your work.
