How To Repair A Bicycle Chain – GCN’s Roadside Maintenance Series

Repair a broken bicycle chain on the roadside with GCN’s latest cycling How To.
Follow GCN on YouTube: http://gcn.eu/gcnsubs
If your chain breaks when you’re out on a ride, don’t panic. We have a couple of simple methods to repair a bike chain and get you home.
To repair a chain on the roadside you will need:
A chaintool
A powerlink, quicklink or master link
If you don’t have a powerlink or one of the special joining pins, you can still get home. You’ll need to put a bit less pressure on the pedals and change the chain before your next ride. Rejoining a chain using one of the existing pins is not recommended by any manufacturers.

Can you Give Me Your bike Because i have No roadbike. @GCN
Shimano just introduced the 11-speed power link, has been missing for quite a while. It's "named" SM-CN900-11 :)
anyone know what specific multi tool that was?
Hi, is it important to use 11 speed chaintool with 11 speed chain or I can use any multitool with chaintool?
Where'd you get that multi-tool?
Excellent tips, thanks a lot!
If you use a chain tool, keeping an extra break away pin in your saddle bag is completely unnoticeable and easily reduces the wear and tear and complexity of removing the link
how did you not get your hands dirty?
where can you get one of these chain links and will they work on Shimano, SRAM etc?
I remember I was out with a friend and my chain broke. We had no tools or power links so we tied a rope around the frame of my mates bike and towed me home lol
How did you get that chain to break exactly at that time? +Global Cycling Network
Sounds like Bear Grylls!
His poor bawls.
What tyres are on that bike?
Yeah how Did you break the chain? ?
I wouldn't do the second method as it has caused me twice as many failures as I had planned for. The problem with the method is identifying the weak link, you will forget where the fixed link is and it will fail shortly after that. I would recommend carrying an Altoids box with Shimano master pins and/or Sram power links(and while your at it, put some patches in that box and presta to shredder valve adapter so you can use the air at the gas station). I like the Shimano pins as they are tapered and extra long so you can simply push the pin in to the chain, then force the rest of the pin in with your chain tool. The extra length of the pin just snaps off. Its much easier then taking out a link if you have the pins and makes a factory strong chain repair.
Thanks for the video. How often does a chain breaks though? Anyone? Fellow cyclists out there
What are Dans overshoes (make) with the big reflective patch on the back ?
1:40 -Dang he broke a shift cable as well and had to tie it off like in the other video. What a rotten bit of luck to lose a cable and a chain in a single ride! 😉
Quite useful if you dont want your bike to let you down!
What is with the different bikes?
Hardly surprised it snapped – its a shimano ! KMC have been far more reliable for me… ;)
what can we do if the wheel spoke is broken?
Definitely the most helpful series so far, thanks guys.
. A tool bag has no place on a road bike. Obey the rules…
Good thing you didn't go down. Sometimes a broken chain causes the rider to hit the pavement.
What's up with that rear dérailleur cable?
Broke my chain around 30km for home and my chain break wasn't big enough for my chain (KMC Devil) luckily I was able to walk/coast to the nearest shop.
I think the start of this video is the best one I've seen on GCN!
best to keep a power link with you,,or you will have problems
Hi guys, when do you recommend changing a chain? I've heard many different recommendations and had 2 chains snap in the last year an a half so what would you guys say?
couldnt you post this yesterday? today we needed to reair a chain!
First swear on GCN?
Hi. What chain lubrication used?
It's also handy to carry an extra rubber glove so you don't get oily hands
'ahh you're f'kin kidding me!' – that sums it up nicely!
Where has Simon been?
Liked after 8 seconds. Brilliant.
I want to know how you were able to deliberately break the chain like that? Or was it a happy coincidence the camera was rolling? ;)
Great tips and tricks!!! Thank You guys!!!
Might have some bigger issues with that rear derailleur cable. 😉
The Powerlinks are definitely the best way to fix a chain, IMO. You don't have to shorten the chain and it's as good a fix as possible…
I think its time to buy a multi tool ! :)
