It's good to be prepared. Make sure that you can fix your chain on a ride by taking a multitool with a chain tool and either a powerlink or a Shimano chain joining pin with you on every ride. There is another way to hack your chain and get home, but the first two methods are far easier.

I learned this on the fly...I did have a multi-tool that had a chain tool, Loved it.
always bring a extra couple of links with you, in your saddle bag or tape it to your seat post then you can have use of all your gears if your chain goes
Simon is the best presenter.
Thx. The tools arrive tomorrow with new links and I am repairing my sister-in-law's bike chain.
How's she paying u, 😂😂😂🤣
@@aaronlobo5034 You charge family to help them? It says a lot about you kid. Your parents let you down badly. You talk like a virgin too 😁
I always have two KMC quick link on me they saved me (and my riding buddies) couple of times. Of course I learned it on the hard way when I had to walk back home with a broken chain...
Just a reminder if you need to shorten your chain with FS bikes you will have even less usable gears because of the chain growth when the rear compresses.
Thanks for the great vids, I watch and re-watch ever day! Would you consider doing a video on trail side rear derailleur hanger fix should it get smashed off a rock? Thanks!
this happened to me just now on the way home thankfully amongst the tools i pack in every ride are a spare pair of power links so no issues there whew!
cheers mate ill be on my bike tomorrow now that ive fix my chain. i thought i would have to by a new chain but thanks to you guys i can save money for some deathgrips...
Brilliant video. I love this channel 👍😁
Very clear and informative video 😀
good job
I bring a little bit of wire (coat hanger) to keep the chain together while putting it back together. Super annoying when it keeps popping
Robbie Keane I was wondering how Si was going to deal with this but I think he was using his knee to push in the RD (and create slack). If he wasn't, it is a good trick and how did he do it?
Mike Williams you can pop the chain off on the front chainrings and let it rest around the BB. That creates enough slack to easily reconnect the chain.
Calvin Iba That works on my road bike and older MTB's but as I found out this winter it didn't work on my fatbike (with a new SRAM X5 RD). There was still too much tension and at -20C I didn't have a lot of time to mess around (so I now carry a bent length of old spoke). Given the small big ring and the move to stronger springs to keep the chain on there isn't a lot of extra chain left. I assumed a clutch type RD would be even worse.
Some sram derailleurs have a cage lock that allows you to lock the cage in a position that slackens the chain.
Is it possible to use other chain links such as SRAM with KCM to fix the missing link
Hey GMBN,
I own a Cannondale lefty carbon rush. I have one problem with my bike's chain. It keeps snapping every time I make a hop or down multiple stairs! I am fed up with buying new chains and I need an explanation of what causes my chain to snap every time! I am looking forward to your reply. Thanks team!
Nice guide.
The chain is threaded wrong on the rear derailleur. It should go behind the notch.
Is the chain effectively weakened if you use the method that reuses the pin?
I didn't have bike tool in my country Qatar does other tools work
Where did you buy that multitool?
last week my chain broke twice. TWICE!!! once on Friday and once on Saturday. Saturday I was not able to fix it anymore. On Sunday I went to church.
wasnt that a single speed power link, after looking at many a powerlink today it seems that a single speed is straight and a multi speed curved?
I've re-used a pin that came out. Bloody determined skint teenager ;)
Global Mountain Bike Network I dunno how it is for other company's but for Shimano newer XT and XTR stuff you really need to check the rotation direction. Sure it will do the job if you get it wrong on the bike but not so good (gears can jump and make a lot of noise) and even if you chain is full functional it can damage all your chain rings.
can you use a shimano joining pin with a sram chain?
when he's checking the gears at the end he's got the back wheel off the ground with both hands on the handlebars - how? thanks!
Love it
Is it me or nobody talked about simos leaving gcn and joining gmbn ?

Any suggestions on how to break off the Shimano centering pin on the trail (assuming you don't have a set of pliers handy)?
Mike Williams use the end of the chain tool where the pin pops out when you're pushing it out. stick the centering pin in there and break it off.
Remember that some chains have specific orientation requirements, e.g. Shimano chains must be mounted with groupset description / logo facing away from the bike!
RCalundann SRAM Quicklocks (for 10 and 11 speed chains) also are uni-directional -- they have a small arrow on them indicating the orientation. (Not sure about Quicklinks)
Random question: is that an 11 or 10 speed chain you are fixing? Reason for asking is that I bought one of those multi-tools recently, but didn't realise it is only compatible with 8/9/10 speed chains while I run an 11 speed chain - wondering if it will still work?
Did you ever find out if the multitool worked with 11-speed? Wondering about buying the Crankbrothers m17 or m19 myself.
Si you forgot to point out a very common mistake. When threading the chain through the rear mech. Make sure that the chain is threaded through the the jockey wheels correctly and not touching the piece of metal that joins the cage plate together. It saves time to check twice and relink the chain once, rather then having to break the chain again because you made a mistake.
Most definetly, or your mates may call you an "Absolute Knob" .....take it from me, one simple, easy to make mistake can haunt you for ....ohhhh, nearly 20 years.... still that's all part of riding, mates taking the pee out of each other and laughing on the stacks ....that's what makes it such fun!! To be fair, never made the same mistake twice!!
I’ve reused the pin that came all the way out 🤔 just lined it up and used my chain tool to push the pin back in 😳 took seconds tbh .............was this just luck .....?????
Question:
1. When rejoining chain (standard chain link) is it safe? because is the most common option I know and you just can't buy Shimano PINS easily especially in my area.
2. Can you install two or more POWER LINK (Missing Link)?
BTW very practical tips simply the best especially on actual situations.
+Aanonymous88 You can put more than one power link in. If you've snapped it I would recommend replacing the chain but as a short term solution extra pins or quick links can be a solution.
+Global Mountain Bike Network Thanks a lot!
Isn't this the guy from GCN?
Sometimes even roadies want some action! :D
What multi tool?
If you just put back that pin, will it be strong enough, or you should buy a new chain as soon as it is convenient?
I have to make some similar repair on my chain. Only difference that I have some spare links I can put in place of the damaged one.
+RelakSHUN It depends how old the chain is and how well you repair it. Personally if the chain is a bit old and it breaks I will just replace it because I dont trust it. If it is quite new I will carefully repair it. Neil
Thank you.
The problem was actually that the chain were caught by the front cogs and bent, so I expect after replacing the wrong links it could serve for a couple of hundreds kilometres.
I successfully fixed a chain by bashing the pin between a chunk of metal and the pavement. I'm still using the chain 6 months later and even competed in a cross country race with it
Dam it's Xmas eve and I didn't bring my tool lol and, my chain snapped , I Gona walk from maybe 25 mile in the dark . O well I can do it's just the time it takes .
wow well this video can out 2 days late HAHA, well this is what happened to me 2 days ago i didnt know what to do i snapped my chain and thought it was broken and cant be fixed, so decided to chuck it in the bin and walk a mile to the bike shed. when i got there the guy was like its going to cost you £70 for the whole gear as you cant just buy a new chain buy its self, or he will do it for free if i had the snapped chain on me, at this moment i was so pissed. i had to walk all the way back to the bin and walk back. (my life must suck)
What frame do you use?
Santa Cruz Tallboy 29er
I know you guys are mainly focussing on riding skills and maintanance in your how to 's. But did you ever consider doing some on trail buildin?. Now it's nice and good if you have a trail to ride on but it's also very important to build them in the first place. So i'd appreciate if you guys maby consider giving us a little bit of content on this issue as well.
MrWIWARD Thanks for the comment, that has been discussed already here at GMBN, it is on the list. Thanks, Neil
B
Why is this video on @builtofficial corolla video
Im gonna have to use the old hammer and flat head screwdriver trick 🙄😩Ouch no chain tool here
You forgot how to solve a stiff link, simply hold the links either side of the stiff one with your hand and wiggle them back and forth inward and outward in different directions until it moves freely :)
that info is what i have been looking for! thanks, will try it right now.
I have all the tools on my pocket but my luck never used chain tool !!! I use to replace chain each 1000 km .... maybe the reason ....
Where is the chicken run video? Also I recently watched a bike wash video by Marc but can't see it anymore
ku5hty I was wondering where the bike wash video went, too. I saw it in the videos list and it was mentioned in the Dirt Shed Show but I haven't seen it since!
they dont zoom when the connect them
what multi tool is that?
+Simply Tom It is a Crank Brothers M17 multitool.
Hey, when you do how to's can you link the website you but the grease, cleaners in description? Global Mountain Bike Network
WIsh i seen this a few weaks ago... lol i pushed the pin the whole way out. I managed ot get it in by wedging it in and pressing it back in with my knife. took about 30 minutes hahaha
U got a loicense for that knoif m8
Why is it Si tho?
Why won't mine go through.
It won't seperate
you routed the chain through the Rear derailleur wrong! I can't watch! Its bike torture!
That is a complete lie about the pin not able to be put back. All you need is a Small thin head Plier that can lock on the back ( dentists, orthodontics ) and hold the pin on one edge so that one long edge is seen. Bend the chain link before joining them so it holds tight on the chain split tool now hold the pin inside the inner part of the chain split tool and start moving the tool till the head meets the pin, slowly push it in until you feel pressure then stop immediately. Now unlock the plier slowly and slowly push the pin in with the tool. It could take a few tries to line up the pin properly but it works great. 5 MINUTES tops !!! . Basically you are holding the long side of the pin up to the hole untill there's enough force from the chain split tool head to hold it straight .
I thought Si was a road biker?
Si: "when you push the pin all the way out, there is no way on earth that you can rejoin it.."
Really?
When I fixed my first broken chain on the trail, I did exactly that (had not a single clue what I was doing.. :D), but after some minutes I got it to work perfectly.
Must have been some kind of beginner's luck :D
LauritzNo That is lucky! It is almost impossible to get the pin back in.
Last year I did it with two stones...
Good job Fred, and did you do it alone or did Barney help you? :))
I THINK THE ONLY THING I UNDERSTOOD IS A SHIMANOO TOOL-
Need more than a chain tool i am afraid . I just spent 2 hours trying to get the pin into the hole in link .Of course here he has a special Shimano pin .Pity he did not mention this at the beginning .. He just shoved it in .Took me 2 hours to do this . This is the MOST DIFFICULT part of the process and it is GLOSSED over Here .How about showing us how to fit the pin WITHOUT the Shimano pin . Not STRAIGHT FORWARD I am Afraid . All weel and good if you have idealised tools . What if you dont't?
Isn't he is GCN man
This guy kinda sounds like Jenson Button.
For the love of Pete, only close up shots please, 3 feet away shows nothing.
bear grills fixes snapped bike chain
I thought simon was a road cyclist
Focus on the damn chain
Visuals are not quality; need to see what he’s doing versus talking.
why would manufacturers produce chains that can be snapped by human muscles? so ridiculous. this is not a motorcycle chain ffs, it's just a bike.
Not clear explanation plus too far filming
WOW-I THINK ILL JUST BUY ANOTHER BIKE-TERRIBLE VIDEO-
