I started watching u when i was 7 and because u taught me nearly everything I know i have a better chance of getting my dream job (bike mechanic) when i was 12 i got a apprenticeship and it's all cause of u thank u

Hey Seth, I’m a home mechanic bike flipper that’s started about a year ago. I came to know you very early on in the journey and you helped me a ton. Not only did you introduce me to more services, but you also taught me about trails and events and parts. I just wanted to thank you because without your videos, I don’t think I would be anywhere near where I am today.

I’ve watched a ton of KZfaq and read several books on bike maintenance and I really appreciate the simple approach you took here. I’m sure plenty of others will too 👍 Well done.

Please do more videos like this! Suspension setup, mysterious creaks, brake bleeds, etc - all would be valuable additions to such a series! Your super-accessible approach to bike maintenance and repair is just what “a friend” needs! And I’m sure I’m not the only one who has such “a friend”. 😉

As much as I love and appreciate the park tool video tutorials, I've watched their video on derailer adjustment countless times and for some reason it might as well be in a foreign language to me because I get lost and confused about what each adjustment does. You managed to explain it in a way where I no longer feel afraid to touch my derailer and try to fine tune my shifting. Thanks Seth!

Seth you are incredibly good at explaining bike mechanics. Other videos often assume you already know a bunch and skip many explaining steps, leaving the viewer lost and confused.

Lots of "entry level" MTBs still come with 2x, or even 3x, drivetrains. Could you make another video like this for front derailleur troubleshooting to help those people? This is great info for those that aren't very mechanically inclined!

Big fan of being entertained AND educated. I would love more of this kind of stuff for sure.

Great vid even for someone who is experienced. One additional tip. B tension on full suspension bikes should be set with the rider on the bike with the shock unlocked, and ideally at their riding weight.

As a college student who doesn't get to spend a lot of time riding my Trek full suspension like it's actually a trail bike, I really appreciate this. Thank you Seth, with this video college kids like me can avoid a trip to a bike shop (and an unfortunate amount of money down the drain) just enough to keep commuting until I can go out on trails again. Your videos are 100% of the reason why I still love learning about bikes and riding as much as I can!

I wish this tutorial existed seven years ago. This is the best explanation of derailleur adjustments that would have saved me hours apon hours of self learning headache and heartache.

Best explanation of derailleur adjustments ever... "Floating Derailleur" cracked me up.

I think its great that you are so inviting to all potential mountain bikers! Some enthusiasts tend to be snobby like they are some special elite class. We should be welcoming to all and realize everyone has to start at the beginning some time!! Thanks for this informative video Seth!!

The easiest derailleur tutorial to understand on all youtube! Everything is crystal clear. Thank you Seth!

I can’t believe how long it took me to just find a guy who just teaches what the parts are called first before screwing around with the thing! 👌👍

I've been working on bikes a long time and I still enjoyed this video because you broke it down easily and efficiently. The one common problem that you left out is gummed up housing. I find that one all the time. Love your channel.

Excellent concise tutorial on bike shifting. I've seen many of these types of videos and this is one of the best explanations I've seen

My 11 yr old just watched this, went to the shed and put his bike on the stand. Cheers mate. :)

Well Good Seth! That was a wonderful break-down of shifting assessment, management and repair of things in a way that the average person can digest. . . But I have a point of contention "because the chain's pitch grows in length as it wears. This is the most important type of chain wear, and the growth comes from the bushings wearing with the chain pins. Over time, the inner diameter of these bushings increases and the pins groove out." So I have yet to see actual evidence of a chain increasing in length. I am not saying it is impossible, I could be wrong. I have seen chains that no longer interact with the chainring and cassette in a functional way due to the worn out bushings wearing. I respectful submit this comment because I know you know what you are talking about and really enjoy this channels content. And I know this segment was aimed at a novice. You Rock & Roll Seth. Much respect Sir! (P.s. I am a life long bike enthusiast & bicycle mechanic, Pronghorn bicycle, in Syracuse Utah, to be specific.) - M

This is by far the best video. I struggled with some of the issue and this one explained the fixes so good. This is the only video you need.

I live in a country with very few bike shops or maintenance shops so I have been learning to fix up my own bikes. Love your content and I love how so much of it is helpful. A bike stand is incredibly helpful and they aren’t too difficult to make yourself. I made one with my dad consisting of 2 long base legs with a shaft on top and a simple stopper for he seat to rest on. 👍

I’ve been riding for many years, Europe, Saudi Arabia, Mexico, Canada, USA. I definitely learned from this video. Thanks so much for creating and posting it!

God dammit. I'm not paying attention to the video because I'm reading all the nice comments saying how helpful you are, dude! Nice!

This is a very entertaining and fun video about a topic that might be considered mystical by some. I would however add that before replacing a hanger, cable and housing are much cheaper and usually, a more common culprit of messy shifting. Try that first, if you still aren't able to tune it properly, consider a hanger. Also, derailleur alignment gauges, while pricey, aren't that much. Depending on where you get your hangers, could be worth between 3 or 4. And with bicycle repair, check for compatibility as much as you can when buying parts!

Big fan of the simple approach to bike maintenance! Please feel free to make more of these videos (perhaps a post-ride check for beginners, or even when to know to replace a part, etc). Thank you Seth!

Great tips. Thanks for sharing this with us. Love the float test. Tried it on a defective house key and it works. 😅

Excellent. I'll share this with some friends. A simple tip I learnt was that if the derailleur won't shift up the block (towards low gears) turn the barrel adjuster in that direction. If it's over shifting and won't shift towards the higher (smaller) gears, then turn the barrel adjuster that way.

As someone who is just getting into trying to maintain my own bike, this was super helpful!

Great video for someone who wants to start tuning their own bike. I'll be sharing it myself. I still think chain checkers are cheap and easy enough to use, that I'd recommend anyone that is interested in tuning their own bike buy one.

This is a great resource to share with someone to help them demystify shifting problems. I wish I had this when I started trying to maintain my bike during high school. One thing I noticed back then after a long evening of trying to get perfect shifting: Although in the end the drivetrain still made some little unusual sounds with the bike upside down, once back on its tires it shifted fine. For those of us being too close to OCD regarding to drivetrain noises: gravity has a tiny effect on where exactly the chain moves along. What ultimately counts is the sound and shifting performance during a short test ride. Also, a slighty damaged tooth, a slightly bent chainring or an incorrectly installed chain link can cause ticking noises without really hurting shifting performance. (Of course, an incorrectly installed chain link should definitely get corrected. Chain breaking under load is not fun).

simple solution to a common problem. youve been my biggest inspiration for my own mtb channel. i couldnt be more thankful for you and your channel. dont ever stop man.

I've been 'seriously' riding for more than 30 years, but derailleurs were always a bit of black art. But today, I was able to adjust my 5-year old daughter's derailleur so we could go on our first bike ride together. Thanks for the guidance and straight forward, plain speaking (but still humorous and entertaining) take on biking. God bless!

Hey seth, just recently got into mountain biking because I saw a couple of your videos and got hooked. Your videos not only make it very easy for me to digest more complicated aspects of mtb, but are just fun plain fun to watch. It's very clear you put a lot of care and thought into your videos, and you're great at not trying to drill a black-and-white right way of doing things into people which I appreciate. Keep up the good work 👍

This is literally perfect timing I just noticed a a couple issues you mentioned and I just fixed them thanks Seth

This was an extremely helpful video! I have been mountain biking for years and I still picked up a few tips! I would love to see more tutorials like this breaking down maintenance and tuning for things that more experienced mountain bikers probably just take for granted.

Now that I am understanding a bit more and did my first tubeless on the new GT, I rewatched this and have the gears changing pretty smooth now thanks. I feel so new after stopping rock climbing I slapped my head when you just flipped the bike over.

Its rad how you teach to the guy that doesn't have all the tools and knowledge! Ran into many condescending mechanics when trying to learn, I learned something and found it entertaining 🤘🏻🤘🏻🤘🏻 preciate ye!

Thanks Seth! I appreciate you breaking this down for beginners and I hope you continue to provide videos like this!

I know how to do all this but i still watch because there is always a little nugget. Plus Seth is awesome

This was honestly super helpful. I'm learning my way around the bike more and more these days but the derailleur always seemed so scary to fix. This helps!

This video is SO GOOD! Best I've seen thus far for explaining my drive train. Thank you!

This was like derailleur adjustments for dummies and i for one appreciated it 😂. As a car guy who’s not afraid to cut a truck in half and weld it back together it’s sad that mtb derailleurs seemed like another language to me. But this does actually give me a better idea of what I’m doing with it.

This is literally the best explanation of how to fix and tune your shifting I've ever seen. Well done Seth.

I know most of what you were explaining, but enjoyed it. I especially like the float test. It applies to many things, including a lot of electronics.

Very useful video, Seth! Thanks a lot!

What an absolute gift of a video. I looked for this video for hours last week. And you made it all make sense in 12 minutes. Thank you sir!

This is probably your best video for a while Seth! Very informative without being "too much". Bravo sir!

Thanks for this. This is the first video that it has made it clear. I sort of knew but always felt I was not doing it right. Great video

It's like you knew I needed this sort of video this week! Been trying to index my son's gears and I just can't get it right. I thought I knew what I was doing. Love this video, explained and demonstrated really well and showing we can do it without the fancy tools! We have a bent hanger by the way. Thank you😊

I learned specific terminology / anatomy😅 Barrel adjuster: ajustador de cambios Cage: pata del tensor Limit screws: tornillos de alta o de baja B screw: tornillo de tensor 👏🏼👏🏼👏🏼

Thanks Seth First derailleur tuning vid that’s worked for me! Much appreciated

This is by far the BEST tutorial video I’ve ever watched regarding how to tune a derailleur. Thank you Seth!

Thanks Seth! Keep with this kind of content! Always super useful to remember the basics

Always crackin me up! Thanks for sharing all your knowledge!

this video is great, it's really well explained, bravo

You've inspired to me to try and work more.on my bike . thanks for sharing your wealth of knowledge.

I really want to thank you for putting this video out. I have a new bike that is shifting poorly, and must admit I was going to take it to a shop and have them work on it. You have given me enough knowledge that I will try to work on it myself, leaving a shop as a last option. I now know what to look for, and am sure that I will be able to resolve my shifting issues.

Fantastic rundown of bicycle drivetrains! 👍👍

This was the best derailleur guide I’ve ever seen. Thanks Seth!

seriously I watched several videos to adjust my derailleur and this video is one of the best explained I've watched..good job !!🤟

Hey Seth im living in Germany started watching you before berm creek and you thought me every trick I know now I work at the bike shop and still pass your skills that you showed us on KZfaq to other mechanics love you videos 🥇

Cool video. KZfaq is such a boon for anyone wanting to learn skills. I could have really benefitted from videos like this back in the nineties/noughties when I was thrashing my cheap mountain bike round the woods without a clue how to do more than fix a puncture.

dude ur such a good youtuber. I knew everything in this video just from my years working at the bike park, but man I still enjoyed the entire video. did not feel like 12 minutes.

YESSSS I LOVE when you talk about stuff that seems basic, but really most people don't know. THANK YOU THANK YOU!!!

The process you described for adjusting the B tension is actually a great example of scientific method. Thanks for this video best description of how to adjust a derailleur I have seen.

wow, hands down the best video for repairing my bike myself, thanks!

😊thanks for teaching beginner maintenance in your videos. You’re a good teacher

Adjusting my derailleur is one of those things that I do rarely enough that I have to look up how to do it every time. Glad to have this video to look back on as reference.

So many problems solved in one video... many thanks!

I love these types of videos! Keep ‘em coming seth!

Thank you so much for this video! Great content. My son and I ride a ton and he’s rough on his bike. We’ve had a dozen trips to the bike shop to fix shifting issues. Now I can save lots of time and money doing it at home

I’ve always had this problem. Now I can finally fix it. Thanks!!

I learned all this last year when I finally did a derailleur job, but it's been a while and this was a good review.

I've ridden for years. I hate messing with my derailleur and have the worst sense of what adjustments are necessary. This was very helpful.

The other thing I find sometimes with the newer 12S drivetrains is that if you have a chain in need of a clean and a lube it can try to climb a bit and clunk back down. So I tend to start with a good cleaning and lube. Then pretty much the same process! Nice video.

Love you tutorials! Keep them coming!

Fixing to get my first bike at 39 years old. This is absolutely interesting to me and I will probably reference this in the near future to tune my Ozark Trail Ridge that I will be getting. Thank you! And keep the beginner stuff coming!!!

Seth as always thankyou so much for giving us great info and advice.

I learned how to do this the hard way. This is a great explanation of EVERYTHING. I wish i had this. Thanks for entertaining and educating.

One of the best rear derailleur videos I've seen. I wish I knew how to fix the damn gears on my roadbike as well. The front derailleur has a "trim" function and riding in high gears also causes chain rubbing on it. 🤣

Great stuff! Love your style and presentation 🤗

Your tutorials are some of the best, Seth!

Great video like always. Your explanations are superb 👌. My favorite bike channel for sure.

I learned a lot on this video! I connected with your way of teaching, and very much appreciate this.

This video is the best and hit me at the perfect time because I had my chain jump my low gear three times today and get wedged between my spokes a chain ring. now I know how to fix it. THANK YOU!!!

Saving this incase I need It. Thanks for these videos. I found your page recently and I have learned a lot.already.

Love these kind of vids. Keep the tech tips coming!!

Right to the point. Thank you. Been struggling with my fb marketplace special 2014 trek popping out of gear. I found the barrel on the de-railer today and tightened it. Before watching this. You confirmed my suspicions. I'll see more tomorrow on the trail. Answered a lot of my other questions too. Thank you.

Thanks for the video. I have seen a lot of videos on drive train this is the first that make sense

Thank you! I was able to get my bike shifting better than it has in years. I always just figured i could never use my first gear. I set all the tensions and screws correctly, and now i have my full range accessible again. I can't tell ya how stoked i am!

I already knew everything he said, but watched the entire thing, Truly goated content.

Please make more videos like this! Takes me back to Seth’s Bike Hacks Days!

Searched for this literally yesterday - thanks for making it!

I love the float test! You had me rolling. Especially regarding those in your audience who were scratching their heads. 😂

You are a legend, Seth! I don't own a mountain bike anymore (logistics), but I enjoy learning a lot and these videos are super helpful.

Awesome video! I've been adjusting derailers for more that 30 years and I learned something. The B screw is an issue with my Eminent Onset.

Seth rocks. A great video that should be an annual video in rotation for people to watch that cycle.

Thank you for this helpful video. It helped me.

Great video. I was just in your back yard at ABI for the essential maintenance class. I stopped by Berm Park to look around. Beautiful area.

This was great, thank you!
