snap_ drama if it is going over the last gear you need to turn the high limit clockwise. I just had the same issue and fixed it doing just that. I believe that is what makes the limit screw stop the the derailleur from going past that last gear accidentally.

Probably eight or nine months ago I used this video as a guide to getting my rear derailleur set perfectly… The instructions in this video are articulate, well laid out, and very clear cut. For somebody who has absolutely no experience, this is a very complicated endeavor; which this gentleman explains in such a way, that WITHOUT ANY FUSS WHATSOEVER, I was able to perform like a master mechanic from a reputable local bike shop! My derailleur shifts smoothly like a Swiss watch! With that being said I hadn’t yet adjusted the front derailleur, and came here just to make sure I’ve left this gentleman and this channel a compliment, a like, and double check that I’m subscribed! It’s easy to use these things and go on with life, and often it’s just the nature of the world, but this guy did such an amazing job guiding me through this process, if I didn’t stop to thank him & your channel, then I don’t feel I deserve the masterful help!

This is pretty much the case. My appreciation for these videos is indeed part of the reason why I tend to pick Park Tool when I need something to work on my self converted E-Bike, though it helps that the quality of the tools speak for themselves. Would be nice if you could get one of their Beam type torque wrenches with the square socket fitting on both sides of the tool end though, because sometimes the only position you can torque the bottom bracket bolts is one you can't see the indicator face side of the torque from, would be nice if you could flip the wrench around and swap the socket onto the other side....

This is one of the best explanatory videos on how to do this. It's clear this was made by folks who knew what they were doing, and knew how to explain it clearly to others. Thanks, Parktool!

[@Zigonce]

This team makes great videos: in depth explanation, likely problems, animations, great camera angles, no fancy tools... I love everything you do.

[@khalilissa1304]

Calvin is a pro, not just in excellent knowledge of the topic but the delivery of the institution, excellent job.

[@nu66ets]

So clear I could land the friggin' lunar module if he was at Mission Control. Excellent work, Park Tool.

[@wolfinthesno]

100% the best how to video I've ever seen on KZbin, perfect camera angles to see what's happening, perfect explanations of how to do everything. Thank you so much for making this something a total novice can understand.

[@MILNER-HOMESCHOOL]

Great video! my son and I fixed his derailleur in just a few minutes, he went from frustration to pure freedom behind the bars. Park Tools are great, these videos are absolutely the best around. Thank you!

[@Jef1970]

I keep coming back to these front and rear derailleur videos for a refresher before giving our bikes a service. They're concise and clear, perfect tutorials for those that want to look after essential bike maint themselves

[@ZeroMemphisto]

This is by far the greatest video EVER. The pauses, the angles, the voice. EVERYTHING is clear AF. 10/10

[@graff_cruz89]

This man has taught me so much about bikes I have now started working on my friends bikes because of everything I’ve learnt from him

[@richardmcnally2056]

I can’t thank you enough, Mr. Jones, for this video. Your clear instructions and careful demonstration have given me a happy day, washing away a lot of frustration as I tried to do this as an bumbling amateur. Always pays to work learn from a professional.

[@josephbrown4651]

By total accident I came upon this video but I did need to watch it! Let me repeat what many people are saying here: What a supremely clear and professionally produced video. This is a model for what all DIY KZbin videos need to achieve! Thank you!

[@floatingvoter8618]

Calvin Jones, you are a legend. I was a newbie cyclist 3 years ago, but now have nearly 3,000 miles clocked up and two bikes. From watching your videos I have learned to service my own bike and bought lots of Park Tools along the way. I am having loads of fun and getting fit while doing it and watching your videoas along the way. Please keep up the great work Calvin and Park Tool!!

[@chromax3]

Thank you. Being a beginner, I attempted to replace my derailleur using a different video, but I ended up feeling completely lost. The derailleur stopped shifting properly as a result. However, your video came to the rescue and not only saved me but also taught me a lot in the process. Now my bike is perfectly shifting.

[@tomzook]

This video (and the videos on disc brake adjustments) have saved me a whole lot of headache. New 7-speed e-bike came out of box with clanky, unreliable shifting. Everything is smooth as can be now! Thank you, Calvin.

[@hazardmuffin]

I haven't owned a bike in probably 10 years (as a teen), knew nothing about how they even really work, recently got one secondhand that was in desperate need of some love, and thanks to this channel it's now fully operational and running smooth. Big thanks to Calvin Jones ❤

[@tuliobenavidez9952]

Ah ok I understand

[@HighFistShin]

Thank you Calvin. It is a pleasure to watch a true professional at work.

[@SD-tl7xw]

I don't have a gear bicycle but found this video because of the derailleur's awesome engineering.

[@lazerbut]

This is a god tier tutorial. I have unbelievable respect to the team of people who created this.

[@philkism]

I was always intimidated by adjusting my rear derailer and continued to avoid it. When the one came that it was unavoidable I was lucky enough to find this video. This video makes it so easy to do I was very surprised. It's setup perfectly to watch the video as you work on your bike. By the end of it your bike will shift flawlessly. This is a very valuable video, thanks!

[@marktrue7794]

This guy is head and shoulders above the rest. Step by step detailed instructions, you can't miss. Any time I need some help I all ways find this guy. Thanks Man.

[@SammyDunster]

I'm refurbing my 1985 MTB and just discovered this series. This is without a doubt the best tutorials on KZbin.

[@dpwr]

After doing this badly for years, this video helped me understand the perfect technique. No more rub, no more bad shifting. Awesome video!

[@jeffreybarker357]

I’ve picked up a great conceptual understanding from watching other videos-some great ones done by GCN-but the animations and colors made this incredibly clear. This is DEFINITELY the first video for someone to watch to really understand how their gears work. Thanks for putting the time into the production of this one rather than just filming a mechanic doing stuff. This is great, thank you!!

[@geoffpoole483]

The video also shows us what to look out for when things are going wrong and what to do about it. Too many instruction videos regardless of subject just show what happens when everything goes exactly as it should the first time. Bike maintenance is fiddly; things seldom fall into place at the start.

[@jimmyle9248]

Yes yes yes!!!! Give this man a raise. Whoever put the video together should get a raise too! So helpful!

[@Oskar_Zhitnica]

At first I thought to myself “well this is pretty long” but while I’m watching, I’m like “whoa! every tutorial video should be like this”

[@waynemorrison9902]

Calvin is an excellent instructor. He speaks eloquently and is easy to follow. He clearly knows the range of factors involving a bike and is a master of his trade. I have learned a good understanding of my bike. Thank you Calvin for the masterful lessons.

[@gregcannon2167]

I've watched this video a thousand times and you can't mess up if you follow it step by step. Extremely detailed but broken down to the point that anybody could understand. Watch it everytime I go to tune up the family's bikes before a big ride and just now found myself watching it again to tune a new derailleur I just put on.

[@djhatstand7312]

This is the best rear derailleur set up vid I have watched, the way you describe what your doing and why is spot on, no waffling on just clear and concise instructions that are easy to follow, the way it should be, you have gained another fan

[@alanhaze3192]

Never realized how important barrel adjusters are in the whole process...thanks for the invaluable tips

[@gregorloff5266]

I completely agree with Cliff Cox. It’s by far the best derailer adjustment video I’ve seen on KZbin clear concise and eliminated a lot of headache. Thank you! Keep up the great work.

[@mikefule330]

Excellent video. Assumes no previous knowledge and explains everything clearly and concisely with good visual demonstration, without being patronising. Thank you. It was so much easier in the days of 5 speed blocks and friction levers!

[@snap_drama346]

I don't understand so my chain keeps coming off when I reach top gear so I just the h limit screw but is clock wise or anti clock wise?

[@kraegm]

This is by far, the most thorough and easy-to-understand rear derailleur adjustment video i've ever seen. That is all that needs to be said. Thank you ParkTool

[@johnlopez4089]

I just bought a core remover for a presta valve. The shop guy sold me a park tool remover. $12.99, I thought that was a little pricey. But the knowledge I just received from this video is priceless. Thank you park tool for these videos 👍👍

[@richardmcnally2056]

Mr. Jones, my bike recently fell over and heavily loaded panniers bent the rear derailleur into the spokes so when I tried to pedal the pedals would hardly turn, so naturally I came down on them with all my weight and mangled the derailleur as the wheel turned a bit. I just finished putting a new derailleur on, for the second time, and I can’t thank you enough for your excellent video and commentary which enabled me to do the install successfully. You are a great asset to cycling in this country. Keep up the good work sir, you da man!

[@alanmartinezrodriguez884]

This is like a university lecture on Bicycle mechanics. I mean, wow. This fine gentleman is PhD level. Bravo!
