Just a note for everyone using the barrel adjustor - rotating it clockwise will release tension and rotating it anti-clockwise will add tension. It's counter intuitive actually. That's why he rotated the barrel adjustor all the way in (clockwise) at the beginning of indexing - to be able to add tension afterwards as you most likely will. Another tip I got from their other indexing video, before adjusting the cable tension, rotate the barrel adjustor all the way in (clockwise) and then give it 3-4 turns anti-clockwise to have a bit more wiggle room in case your cable is too tight to begin with.
You have demystified how to adjust a derailleur. I am 74 and for the first time in my life I have seen the light on this subject. Well done!
same same!
I’ve watched a dozen of these videos and still can’t figure out how to fix my gears
Doddy is starting to look like the guy from park tool
Trumen
Yeah but different hair color lol
Its the chain oil that does it..
I was thinking the same thing!
Calvin! :)
Doddy really saved my bud where, I bought a new Deore Derailleur and didn't even know what there was a mark behind the derailleur, thanks GMBN tech.
One of the clearest tutorials on derailleurs that I've seen. Thanks, now I'll try to put it into practice!
he knows whar hes doin, thank you
I’ve been working on my bikes for decades! (Not a pro by any means) everything from triathlon race bikes, cyclocross, and now my new obsession mtb’s, even my kids bikes. But this by far has been one of the best tutorials on rear mech adjustments!!! The camera angles, the explanation, and technique…Brilliant! Cheers boys very helpful 👏🏽🙌🏽
Thank you so much! Bought a new bike in box that gears where wrong and bike mechanics in town couldnt help me right now so after 10 min with help from you here they work spotless now 😍
This is the best one of these vids for adjusting rear mechs
I'm a total mechanical noob but this vid just helped me adjust the shifting on my bike. Cheers Doddy and GMBN.
Glad we could help!
Thank you. Had to replace a rear shifter cable on 2001 Trek 6500 Mtn Bike. Helped a lot. I've got over 34,000 miles on the bike. My second "bed!"
Holy shit this was helpful! I was going to war for 4,5 hours the day before with my gears, but today after watching this video it took me 20 minutes to adjust them right. God bless you man!
Bravo mate. One of the best instructional vids I've seen. Crystal clear on the steps and the tools and how you know when the adjustments are correct. CHEERS!
I share the praise. Well done, Doddy.
Thanks to you, and this informative video which is easy to understand even for someone like me whom is a beginner MTB'er. After sending it to 2 professional cycling workshops here in South Africa, and throwing a ton of money on them, they could not get my gearing right, and eventually set my bike up but compromised my largest cog, they informed me that my bike needs a new cassette and derailleur. After watching your video and following it step by step, my bike now works smoothly on every single gear, including the largest cog :D Happy days! Well done Doddy!
Dude, you explained that better than anyone I have ever seen do it. Three points, Simple idea and it stuck with me. I did the 3 things exactly as you said, then sat down and figured I'd need to fine tune. I checked the indexing. Big surprise> I was hitting every gear on my cassette perfectly- what a thrill- so easy to do and remember!
Best out of all video so far, much more simple to understand and follow than the rest. Some of higher viewed video drive me mad with listen to the noise and adjust both cable gear and limits screw at the same time which is so complicated and headache. You make adjust so easy to learn for beginners like me. Much appreciated 🙏
I love your tech videos especially when it comes to derailleur adjustments. I will say i feel like there is one thing that you should elaborate on...the hanger itself. As a bike tech 90% of the shifting issues i see are because of a bent hanger. Even the smallest crash can bend one and i understand that not everyone has a hanger alignment tool. But starting with a straight hanger is the base for building your shifting pyramid. Keep the content coming and keep the stashe 🤘
True. So you just have to buy a hanger alignment tool. A simple adjustment that will fix 95% of bent hanger issues is: with the hanger adjustment tool threaded in, lift tool arm up where it is parallel to the floor. Standing behind the bike, pull the tool to the right where the hanger is straight and even with the plane of the bike. Then stand opposite of the rear wheel, let the hanger tool drop to to the ground where it it is now in a vertical position. Pull tool hanger handle up about parallel with the floor or until the hanger it self looks relatively straight. Remount derailleur and check for performance. if it is still bent in too much, then you need to pull out both axis's a bit till the derailleur works effortlessly. if you have pulled it too far, the derailleur will have a hard time shifting all the way too the top gear and/or tend to jam on the smallest sprocket (high gear) and frame. Side note, it is possible to adjust a cast replacement break away hanger, just be careful. It's worth trying before you replace it with a new one.
I've been searching like mad because my derailleur is clearly bent but nobody is offering advice on fixing it!
Thank you Doddy, you so easily demystified set up. I’ve been paying for this service for years… never again. Cheers
Cheers, Doddy. Watched it a couple of times then had a go. You made it a simple task. Thank you. 🙂
0:39 Damn I was not expecting getting flexed on by Doddy today
Especially with a beaten up XT derailleur. Not even an especially expensive piece of gear.
So simple when you explain the process! I've always been a bit baffled on what to do, largely because nobody has ever taken the time to explain the process in detail - Thanks Doddy!
Gmbn tech have got me out of a sticky situation many times , thank god for youtube when on the trails 👊👊👊
Thank you....the cable tension was the part that I was missing when I was making adjustments. Thanks!
Thanks for the tutorial dude. It allowed me to set my 12 speed Shimano derailleur like a pro. You totally rule the game!!!
Doddy you legend! Been struggling with my LTS ghosting and skipping gears then here you are you've saved the day.
I started cycling with internally geared hubs, so these guides have been super useful! Really well explained and easy to follow.
Thanks, man. First time adjusting my gears, worked flawlessly following your guide.
Excellent guide video! It's fun to see how much GMBN have grown, i started watching when scott
, neil and marc were the main presenters back then.❤❤❤
Thanks for taking the mystery out of the mysterious derailleur system.
Brilliant thanks for this, always looked at those gears and wondered - getting out to adjust them today - great video - thanks for the help!
I've not been on my bike for WEEKS bc I flucked my derailleurs trying to fix them :/ THANK YOU: I was just about to go do another search for how to fix my mistakes! Perfect timing
Best vid I have seen on the subject. Straightened my ride out
It seems I do this just far enough apart to where I forget, and this will be my Go-To refresher vid in the future. Doddy explains it all clearly in minimal time so I can still catch a ride before the sun goes down - Thanks!
Thanks for this then 👍. A nice clear explanation and demonstration how to get it right. It's not hard just know what you've got in front of you and go carefully and all's good. I've currently got my bike on the stand cleaning and replacing parts,next job is reset the sifting after new cassette and chain, I've done it many times but always felt like a dark art, so thanks for setting my mind at ease. Looking forward to cracking on with it now!
Thanks Doddy, been doing this for many years without really knowing a correct adjustment for the b screw. Used to just play until it works well enough. Good to know this time it's done right. AndyB
Thanks for the info. I was able to tune my Deore transmission on my new Ibis after watching this. Very helpful.
Great tutorial.
I love that your kitchen is your bike workshop - good lighting and somewhere to wash your oily hands and bike parts
Simply an awesome and well structured tutorial, Thank you!
Thanks Doddy! Your vids are are always super comprehensive.
Super helpful... thanks, Doddy!
Thanks for posting this :) after watching I managed to get the gears on my old bike working again.
Just watched this and makes waaaaay more sense now! Just got my bike back and the gears were fine when it went in, but not dropping down like it did! I know my mech was removed, so I will check the adjustments now! Thanks
This video was so helpful! Just built up a hardtail and was having issues.
Finally found a video where there's no waffling on. Thank you!
Best adjustment video to date. Thanks. My gears are perfect
Thanks for your video, my old man brought me a new Ragley BluePig and it hadn't been set up correctly, your tutorial helped me set it up perfectly! Peace 🤙✌️
Doddy is the man .thanks for the info .great stuff.👍👍👍👍👍
Thank you very much, you really helped me big time. I'm doing a bit of a tune up on my Specialized rock hoper tomorrow. Replacing my R. Derailleur and setting up my full suspension. Again thanks a bunch 👍👍👍👍
Many videos out there on this. But this one is the clearest and the best. Thank you.
Great video👌 very good explanation and easy to learn quickly. Thank you teaching me how to adjust the derailleurs✌😍
Best video for adjusting your rear mech! Thanks Doddy!
This video really helped me. It took a couple of hours but I got there. Thank you so much!!
Thanks! What a great video! Gear adjustment has always baffled me, this has been such a great tutorial.
Glad it was helpful! We really appreciate the support! It's a tricky thing to get your head around! 👍
Timings spot on, just got my wheel back and know that the limits need adjusting as it doesn’t go onto the smallest cog.
Comprehensive yet short vid! 👌🏻
2 tips that made doing this way easier for me:
- *pre-stretch* new cables - insert new cable, clamp it on the very end _(excess you gonna cut anyways)_ and pull the housing away from the frame, won't need to re-adjust anytime soon
- after resetting the barrel adjuster wind it out 1 turn, to allow some room for error
Great vid Doddy. I know what I'm doing tomorrow
Thank you! I have the very same derailieur with the very same set screws. This was immensely helpful!
Thank you so much for the video, it helped me adjust my gears quickly!
Honestly this is the most important topic for a cycling channel. Ask any random person who doesn’t ride a bike why and they’ll usually tell you that they have a bike, but it’s broke. By broke they usually mean the gears are knackered.
Exactly that! Hopefully this keeps lots of bikes on the hill
Outstanding info. Even the bike mechanics in the UK sound so refined and sophisticated. Amazing country
You guys are absolute legends 👏🙌 thanks helped alot
Well that worked! And I avoided a visit to the bike shop. Thanks so much for a clear explanation of the actions and the order for taking them. Excellent!
Had to watch this again sort my gears out 😢 I just wish I had a bikestand. Gotta love GMBNTech💯
Stands are easy to make. Google "homemade bike work stand". There are several designs and videos out there. Not as fancy as store-bought, of course, but very basic construction and entirely serviceable. Best of luck.
Smashed mine on a skinny last week. Bent it back but it just wasn't quite right. I adjusted it a bit and now it is good as new. Thanks Doddy!!!
This is the video that It finally clicked for me how to do it. Must have watched 20 videos over 3 days problem after problem and finally my bike changes into the gear I tell it to.
Greatings Sir, I just want to thank you. Your video helped me today. I couldn't find out how to adjust my gear system and was weisting lots of time and energy while I had lower back pain so I was really suffering. I have googled it and found your video which really eased my day. Thank you so much. I really wish your good deeds return to you man. For you shall receive what you give!!!🙏👍👏🙌🤝✌👋🤞
Very Informative Doddy !!
What a fantastic tutorial. so clear.
Greetings from Montana USA!
Great explanation. I've been doing this for decades but still checked out this video and learned.
Setting up a new bike with 1x12. Didn't know about the mark on the back of the jockey wheel cage. Thanks!
Something that helps me fine tune the barrel adjuster is to turn the bars hard left and turn the barrel in the direction that the shift is having trouble moving. Works great on-trail helping out friends compensate for cable stretch.
Eee: I like a good tune, you're forced to!
🎶😉🎶
Thank you so much..just what I needed 🤟
Excellent instructions. Thank you…job done
Excellent video. Very helpful and well explained. Thankyou.
Thank you very much, such a clear and useful explanation!
This was plainly laid out and I was able to stop uneven shifting. Thank you!
Thanks for your help, awesome instruction made life easy!
Great explanation, mate. Thank you for the video! :)
Thank you so much for a great video, super well done! It has just helped me in reparing my sons mtb. 👍🙂
Thanks for the video. Very helpful 👌
Great video! Thanks...just used this for a successful upgrade from XT 1x11 to XT 1x12 🤘🤘🤘
Whoa, this made it sooooo much easier!
Wow.. These are some really great videos.
Thanks a lot👍
Just converted my son’s bike from 3x9 to 1x10. This is going to be a big help, thanks!
Thank you, I got my bicycle ready for the fall season.
Epic video. Just setting up my new bizango pro hardtail. First decent MTB. And ye this was a massive help! Thanks.
After this video, my gears are going through like butter. Thanks mate!!! 🤛
Such a helpful video thanks 👍🏻
