I've been repairing bikes since I was a child. No-one taught me, and over time, mainly through trial and error, II earned a reputation for being able to fix almost anything. I don't drive because of my (adult) ADD, so have cycled almost everywhere in my life. Consequently I consider myself something of an expert. Not being arrogant or 'owt like that. It's just accrued knowledge over the last 45 years (I'm 51 now but like I said, been repairing bikes since a child). But dang it, this bloke always, and I mean *always* teaches me something I didn't know before. Brilliant. So thanks RJ, and I really mean that. I can imagine that something that took just a minute or so to fix in reality then becomes an hour or two when you add in setting up the camera, various tripod positioning, working the camera itself, all the way through to editing the video and posting it in here for us all to watch, be entertained by and learn something from. Nice one, thank you. 😊

Thanks RJ you really saved me a few years back I moved to the Netherlands and needed to earn extra money for my family and fixing bikes to sell really saved me as I knew nothing about bikes.

Aaahh. I am really very grateful to you. I have had this fork for almost 2.5 years and everyone told me it was broken because it hadn't moved. thanks to you, it works perfectly now. lol 🤣

I had my doubts that that fix would be that simple. But I did exactly as you explained, and my lock out for my shocks work again. Thank you so much.

This was exactly what I was looking for! Cap fell off on a ride and when I tried to put it back on the lockout wasn’t working at all, needed a lot of tightening and now it’s perfect again. Thank you 👌

I don't even have suntour forks. I just enjoy your videos.

I have this fork. I have this problem. I couldn't work out what was wrong and was going to buy a new fork. Your video popped up. I watched it. I still have this fork but I no longer have this problem! You're awesome. Thank you so much!

Thanks for the great video! The bike store said they couldn‘t repair it because it was very rusty and they told me to by a new one. I just sprayed some WD40 and I could repair it at home. Now it works perfectly fine :)

Dude thank you!!! My Raidon fork started making weird noises yesterday (unbearable to ride with) every time I compressed or released the fork. It was like a clicking / creaking with a bit of play and sounded like something needed to be oiled. I contacted suntour and was told the noise was normal and to keep riding. Naturally I took the whole fork apart (which I needed to do anyway to increase travel to 120mm). I put the fork back together and still had the same noise! It was so bad that I really contemplated not being able to ride with this fork and if I should look for another one. After watching every video online about this fork I came across yours. Sure enough the Allan key bolt under the lockout wheel was completely loose and there was grease all over. I tightened it and the noise went away. Thank you!!!!

Amazing. Literally the easiest fix and its working again. Thanks

Thanks for the video. Thought 'someone' had broke my fork. 5 minutes after watching your video, I'm happily riding with a functioning lock out!

I'm glad that thru your video, you are able to help a lot of people. I also have the same issue with my suntour fork but unsuccessful so far to fix it. I had a hard bump with a rock on a rough road and since then, the lock out no longer works. When I watch this video, I though this would be the solution but no! the nut at the top could not be tightened, it just turn and turn.

Thank you for this video I was able to repair my folks that were lock in a few minutes. Saving me money for replacing forks as the bike mechanic recommended.

You are a life saver - I somehow lost the lockout lever and my forks have been stuck on no bounce - managed to sort it - Thankyou.

the blue lever is hard to remove ...while using a plastic thingy and also tried with screwdriver ..the lever almost got cracked and broken trying to remove it ..any other ways to remove it sir?

Absolutely unblieable from bikeguy, I was just started the maintenance on this very same fork with my exact intention to service the lockout. Just went to turn on your channel and here you go... absolutely amazing and thanks again for your good work.

Legend mate just bought new bike and this saved me

Thanks! 5 minutes of my life and now I have the lockout working again!

Saved me 60 bucks from buying a new lock out kit ! Super thank you !

Helped me fix my lockout in under 5 mins! Thanks from Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿

Thanks for the video! Saved me some time and money. Thought I would have to buy a new lockout lever. Now I know I can just use a 4mm allen wrench (shown at 1:00). No need to purchase a new lever just to have it fall off again.

Had the same issue with a slightly newer version of the fork you have in this video, but it worked a treat for me and fixed the lockout issue. Thanks a lot mate!

this is why i'm a subscriber.something commonly on bikes needs fixing? RJ has covered it

Mate thank you so much I thought I was screwed my forks wouldn't go back soft man you have saved me was so stressed now I can hit trails again haha thankyou

Thank you very much RJ. 3 days back i told you my lockout was screwed and a video for that is already uploaded. Thank you very much!

Thank you for this vid i was worried i broke it because im a beginner in biking and i fixed my fork just by watching this vid! Thank you!

God, thanks for this video, in the Russian segment of Google there is no information about this lockout. I just had to search in English and the first link gave me a solution to my problem))

Perfect how-to video. I was able to quickly fix the lockout on fork using the instructions.

great explanation. What do I do if the 4mm is tightened (in lock out position) and it still does not lock? what is broken?

Hey there, thank you for your guide! Bought a brand new bike but it has non working lockout. I even thought about refunding my bike but your video helped me not to do it. Thank you so much!

I didnt want to touch it because of varranty also didnt have time to go service. Anyway i fix it in two minutes. Thank you :)

Short and useful instruction, thanks a lot! 😄

Thank you! Saved me a trip to the bike shop and took 2 mins to fix

Thank you so much my forks came factory without a working lockout and this fixed it.

This did the trick for my newly purchased (used) bike. Thanks a lot!

While I was riding my hard tale the front suspension got stuck so I took it to my local bike shop. The man who waited on me told me it couldn’t be fix and to replace it would be $190 to 250 depending on the fork plus labor. No way Would I spend the much on a $700 bike. Fortunately I came across your video and it took me less than five minutes to fix my fork. Thanks

This guy has helped me twice I can’t tell you how thank ful I am of this video thanks mate your a like saver 👍👍😑

I dont even have suntour forks but this vid helped me fix my trek bike forks

Thank you so much master.Greetings from Turkey🇹🇷

thanks!! the biker seller wanted to order me a new fork, unbelievable

Thank you so much! My Brand new bike fork was not working good. Now it is fine. It was a wrong lockout setting from factory.

Thanks you VERY much! Now my bike is work! 👍

Thank you for a great troubleshooting video! I will need the cartridge but at least I know what to expect!

Fantastic thanks; fixed my lockout. Spindle was tricky to get out, as had rusted in. But coaxed out after few drops of light oil.

Thank you very much for your support, I managed to repair my bike! greetings from Argentina.

Thank you man, I was able to fix the lockout on my Talon 2.

this is exactly what i want to know. now i solved the lockout on my bike. thanks!

Thank you from germany , this did help me a lot today 👍👍👍

very nice, you save my fork, bro. Thank you.

This fixed the front fork on my Trek Marlin! Thanks so much for the vid!

Excellent advice. Sorted out my son's forks! Thanks.

This allowed me to unlock and get the cartridge back into fork, mine is a simpler cap which is annoying and it just button fits to allen head...at least I will leave it in the unlocked position now till U upgrade the forks.

Great video! Bought a used bike and this was the fix! Thank you so so much 👍

Awesome. Good content as always. Thanks RJ.

Sorted my issue, you’re a life saver dude thank you so much for this video

Nice fix but should do a vid on fixing preloaded forks because they are common and sometimes they are real hard to turn but I know how to fix that but you can help the others who don't know how to do it out nice rj

Thanks for posting RJ. I think I may have made an expensive mistake. I think I may have over tightened the interior 4m bolt because now it just turns freely in either direction and there’s no travel at all in the fork. Any advice?

RJ you rock Taking away the mystique I took my voodoo bizango to 2 repair shops and they said naaah we dont touch forks take it back to the manufacturer for fucks sake !! So I followed ur instructions and within 5 minutes the forks were sorted . I just subscribed thanks Yr a fucking king !

Thanks RJ. Great vid and saved me a trip to the bike shop.

Не нашёл видео по этой теме на русском ютубе, но ты мне помог !!!

Also worked for my Specialized Rockhopper.

Thank you a million worked a treat.

Thanks for the help! I had no idea what locking cap I needed and you helped me with shopping and installation. Thanks

Just put a deposit on a specialised mtb 29ner . But the forks have about 10mm travel !!! Everything else is fine rj . But agreed £200 SO i will have to speak about this problem no doubt .

This worked Great and took me about 2 minutes! Thank you! have subscribed for more!

Excellent thanks 🙏

Thank you! My time was saved by this video 👍

But unfortunately, I think the issue is with the cartridge inside. Let me give it another shot to see if this works. Else, chuck it. The suspension anyway works. It's only the lockout that is not working

Thanks for this RJ and for all the others that have taught me so much about my bikes.

Another helpful video RJ thanks for the input. You really have covered so many subjects and saved people money and time. All the best Andy

Thanks! Just fixed mine.

Good info for the people who need it. For most of my life, "bike" was what I called my motorcycle. Now I'm back to using a bicycle as my primary transportation, in a developing country where the roads vary from pretty decent to mostly imaginary. My bike doesn't have a suspension. That may change.

Thank you so much for these explanations ! I have just fixed my fork lockout

you've made my day by saving hours and £££££. Thankyou

Have you made a video to service Nex4610 V2 Lockout Alu Monocoque adjustable fork?

Exactly what I was looking for and it worked perfectly. Thank you so much!!! Very helpful

Saved my day!

Can I convert this manual lockout for remote lockout by changing the cartridge

This worked like a charm! Thank you so much!!

Thanks for the video! I have the same shock but there doesn't seem to be anything the 4mm allen key attaches to when I insert it. The fork is completely locked out and I can't unlock it.

Amazing video! Can you please let me know how to adjust the 'preload' on the other leg of the fork, please? What exactly Is it?

You're the man as always! You just saved me a lot of time and money! I thought I was going to have to rebuild it.

Looks like my cartridge is bad. Thanks for the video!

Thanks for this usefull tips, from Colombia, thanks again! 🇨🇴

I have been looking for a guide like this for a long time. The bike I am currently prepping is missing the right cap of the XCR fork and what may have been underneath it. Both the 5mm and 4mm Allen screws can be tightened clockwise without stopping. Since I got the bike the way it is now, I don't know if the fork is locked out or just has rough suspension. 🤷‍♂ I don't know what to do.

Gracias, excelente video me salvaste... justo me llego una trek marlin 6 y pense que vino con falla de fabrica y con tu ayuda lo solucione... gracias

Thanks v much for your video i eventually did it..after severel on going efforts & bit of cussing lol.. Why do both the screws turn at once if your not carefull though.. excellent vid & simply explained etc eternal gratitude again.

Worked like a charm on my voodoo bizango! Thank you

Dang know I know what the hell the lockout does bruh thanks so much because I’m getting a not I storm 2 which has a lockout lever on the for thanks so much!

I did exactly what the video said, but still the broken lockout (and harder to turn blue knob). Is the cartridge broken?

Thank you. This did the trick four me

You might wanna put a version of sr sontour fork..because i follow u but i damage thr locking cup because it has acircular locking pin that i thought i dont have.

What does it indicate if the Allen 5mm will not tighten, it snugs but never tightens almost like trying to tighten a bolt with the nut fee spinning on the other side. The 4 mm also never stops turning clockwise

Thank you so much RJ.. This is very helpful

You actually saved me, thanks !

Hi all. My suspension won’t lock. Have taken it all apart and the only thing I can assume is the canister is shot. I’m quite new to this so is that a thing? I’ve tried the Allen key thing and it makes no difference. Cheers

Brilliant and simple!

some video about how to fit 15 or 20 mm axle to 9 mm dropouts,

dont even have the same brand forks but this still help me out cheers
