I would cut old chain off with an angle grinder . But I’m a barbarian lol
Shimano hyperglide pins should be inserted from the inside – I never knew that before and did it from the outside for the last 25 years! Never had a problem but the explanation of why it should be done that way was clear. Thanks 🙂
what if there is no chain…how do you determine what size and length chain to get ? i have a torker tristar single speed tricycle…it uses 2 different sized chains…..the front one looks like a typical bike chain as far as the link size…but this chain is too small for the rear chain….pedal crank to coaster gear…then a 2nd chain from the coaster to the rear axle cog….
even better , why in the hell would a 400 dollar tricycle use 2 different sized links on their drive system ?!?
But I don’t have a can-do attitude. Where can I get one of those?
5 hours ago I had a dirty Road Bike now I got a single speed with a lot of slack on my chain. Jeez I should have watched this before I started.
I miss Ben
Anyone else use a shoelace to remove a master link
Very well done videos! you include so much more details and side demonstrations, it make this process a lot more doable for a novice person like me. Thanks
Problem is following: how often do we change our bike chains ? Maybe once every few years ,chain tool costs more than a chain…
Sooo, new chain has stock grease which is for stocking chains for long time, not for lubeing, i allways wash that off, second kmc makes all the chains, all you have to match is speed
Hello, good day! Is it possible to use the 10s KMC chain to 9s gear? Thanks in advance.
best bicycle repair videos on youtube, well done guys
If you’re unsure it’s always good to watch a couple of videos before you start installing anything… then you don’t have to be the idiot that blames someone else for your own incompetence!
I watched this video following the one about repairing a broken chain. In the video about repairing a broken chain, it says it is only a temporary fix to get you home, where you buy a new chain. But this video, your break the chain, run it through, reattach it, and its good to go? So what was the point of the other video, and why would I have to replace that chain and not this one?
Just to be proactive, I’m looking for answers in general regarding installing new vs repairing bike chains, and not something like "well if the chain broke it probably needs replaced".
Thanks! This video sorted me out… just replaced my chain.
Where do I get the mechanic from?…
I don’t want to lose orientation while swapping out my chain!
This is the only video that I could find mention of driving the pin in a particular direction. Good job! Wish it was mentioned in the other park tool chain sizing video.
sounds like a canadian..I like the canadians I have known
Can we reuse the same connecting rivet which was extracted once to connect the chain again?
When mounting a new 105 chain, I recognized that shortly before pushing the new pin fully in, it got pretty loose for 1 or 1,5 turns again before resisting even more, so I stopped. Looks good from the outside, but I found it irritating that it felt like pushed too far.
So relating to the video, I experienced 3 force surges,
Can anybody relate?
Pro tip: NEVER buy a bike from CanadianTire
8:10 THANK YOU….and nice beard
Look like a healthier Roy Nelson
I’ve installed then chain but I find it skips on the smallest 2-3 cogs at the rear. I know it was one link short on the previous chain, the the size still seems good. I’ll check for seized links. But any other tips?! I also replaced all gear cables as well, but the alignment looks good.
Someone from SRAM told me to NOT remove the original lube on their chains because it’s the very best chain lube.
Also get a good chain tool, Wal-Mart ones suck.
I replaced the chain on my bike and now it makes a pop kinda like its trying to skip but only in 7th gear and only if i push hard on the peddels
What if you’re not strong enough to take the chain apart with the tool?
Lighter? Yes. More durable? Not usually.
After letting bike tire down, loosening back break, removing tire, following instructions for measuring new chain without existing one, fitting connectors, re-threading new chain, putting back wheel back on, adjusting breaks and testing gears all work (and all upside down and reverse to videos as video instruction bike was suspended right way up), and after 5 hours of "can do attitude", I changed my chain. Yeh! Thanks very much lads for detailed instructions. Oh "girl power" by the way. Female. Never done before. Got frustrated many times, but never gave up. Now I’m mobile. Thought – could you do a video for those that aren’t able to suspend their bikes right way up to repair chain?
From England, UK.
Can I order ParkTool products in Pakistan
Can we put a master link in Campagnolo 11 chain when it needs temporary?
very informative.. I love it.. thanks 🙂
Say "CAM-PIN-YOLO" one more time… Pirk Tools :))
I ended up putting my chain on and it’s was too big but I do not own any of those fancy measuring tools to tell if it’s too big but I can’t tell it’s has too much lengeth any other way to tell if it good enough lengeth
What a great video!
What if you dont have the old chain anymore how will you fit the new one?
5:05 horrible video angle… Can’t see wtf you’re routing exactly when the camera keeps cutting at the worst timing…
how would i remove a chain on a old 1970 schwinn bike chain? i wanted to keep that chain, but take it off for cleaning, i dont believe it has a master link.
Newbie question. If you use the chain tool to break the chain by driving the rivet out , why use a different rivet to reconnect ? If you drive the rivet out, so that the male end drops away but the rivet remains in the outer plate. So when reconnecting the chain ends why not just connect the chain by pushing the rivet back into place ?
I can’t find it
So awesome, wanted just to be sure but this video is so good and informative that I really enjoyed it so much …
Thank you !!!
8:15 " it might be a symptom of a worn cassete so you might need to replace those" throws the metal cassete on the table and … BLAAAM!!!
I guess that this sound we just heard is a symptom of a worn table as well. You might need to replace the table too.
This guy sucks, where is Clavin Jones.
Yay I did it lol
Wish I’d seen this video, 10 yrs ago as I didn’t use a new pin when I replaced my chain. The pin came out and ripped up the front derailleur. It’s what we used to do when I was a kid. I use a power link/missing link now much better idea than the stupid pin.
is there a break-in period for chains?
