While this topic may seem frivolous, every cyclist at one time or another has been plagued with the dreaded case of a tangled chain. It’s one of those problems that is easy to fix once you know how. Generally, your chain gets knotted when the top half crosses over the bottom half. Simply spread those two knots out and pull the chain back over your derailleur and chainset and the issue SHOULD be solved! Here’s how.
Getting stranded on the side of the road or miles down a trail is never fun. In fact, it is one of the main reason cyclists avoid riding alone. Learning some basic bike repair tips can help you feel more confident on solo rides and enable you to be the hero should a buddy have a bike issue. A broken or bent chain on your bike is super common, so knowing how to remove sections of your chain and reinstall it is a necessary skill to have. The following tips will help you repair a broken chain while out on a ride, but first, familiarize yourself with the parts of your chain so fixing it will be a cinch: What You’ll NeedTo fix a broken or bent chain, you will need to remove it from your bike AND remove the broken or bent links. To do that, you will need a chain breaker tool. In the video, we used the Park Tool Master Chain Tool, which is the best tool for the job. But if you are on the side of the road or trail, you will probably want something a little more compact. Most multi-tools will come with a chain breaker attachment, make sure yours has one before you leave the house! In addition to being able to break the chain, it would also be handy to have an extra section of the chain you have on your bike to replace the broken or bent section. However, this isn’t totally necessary. Learn more in the step-by-step instructions below. How to Repair a Broken or Bent ChainIf you notice your derailleur skipping and you are unable to stay in one gear while pedaling, you probably bent your chain. Although you might be able to ride home like this, it would be a little obnoxious and your chain could actually jump off the cassette entirely and break or bend your derailleur! If you have a set of pliers on hand, it is possible to bend the chain back and make it home. If you don’t have pliers, you’ll need to remove the bad section of chain. If your chain breaks completely, it usually snaps as you are putting effort into the pedal or if you apply force in another way, like landing a jump.
TIP: You just removed a portion of your chain, so chances are the chain will not want to shift into the easiest gears on your bike (the biggest rings on the cassette). Be careful as you ride home to not shift into these extreme gears, or you might risk bending your derailleur. If for some reason you had to remove a large portion of your chain, you can by-pass the derailleur all together and make your bike into a single speed! Wrap your chain around the front chain ring and the desired cog in your cassette, trim the chain so it is tight and reattach. This method will also come in handy if you bend or break your derailleur. The Deal with PowerLinksBut, what if you have a PowerLink, right? It is likely that your chain your bike came with has one of these quick attachments. A PowerLink allows you to remove your chain without a chain breaker and reattach your chain without fumbling with pressing a pin back into your chain link. If you have a bent portion of chain and need to remove it from your bike, you can remove it with the PowerLink. However the bent portion is probably not located right at the PowerLink, so you will still need a chain breaker tool. Also, PowerLinks (especially on newer 11 or 12-speed drivetrains) are often difficult to remove without a set of needle nose pliers or special quick link pliers, like the ones below. It is a good idea to bring a PowerLink with you in your pack or emergency kit because it is easier to reattach your chain with. But keep in mind that all chains require different kinds of PowerLinks, so make sure you have the right one.
Ka-CHUNK! Again with the chain noise. But it can mean so many things. Sometimes it’s a tight link, which we covered last time. But when you go in to investigate, you may not see the telltale stiff link. That may be because your chain got twisted during the ka- CHUNK. A twisted link is easiest to spot by looking lengthwise down the chain, and it’s almost always the narrow link. When you find it, fold the chain 180 degrees with that twisted link at the apex. Use the lengths of chain in each hand for leverage to twist the link back straight. Look lengthwise down the chain again, and you can check your work. As long as it wasn’t too severe, you can still trust the chain, but check your shifting to see what caused the harsh shift.
