![]() ![]() Turn the handle to drive the pin into the chain, connecting the 2 links. Be sure that the 2 ends of the chain rest securely in the groove of the tool, hooked on to the "teeth" of the tool. Line up the "female" and "male" ends of the chain in a chain tool (again, available at all bike shops). Finally, once your chain securely passes all the way through your gear system, you can join the 2 ends of the chain and start riding again. In these cases, simply thread the chain onto the rear sprocket, turning the wheel as needed.Ĭonnect the 2 ends of the chain. Some bikes, like fixed-gear bikes ("fixies") and bikes with a hub gear shifting mechanism, don't have a derailleur.The chain must pass this tab without rubbing on it. There may be a small metal "tab" between the 2 small pulleys in your derailleur.Make sure the chain isn't catching or resting on anything besides the pulleys-if so, there will be a bump in your backwards "S". When done correctly, your chain should make a smooth, straight, backwards "S-shaped" path through the derailleur. Take the "female" end (i.e., the end of the chain without a pin sticking out) of your properly-sized replacement chain and thread it around the bottom pulley, then up and around the top pulley. Threading the chain through this derailleur properly is essential for smooth, safe riding. A bike's rear derailleur is the spring-loaded system of gears hanging down below the main rear sprocket on most modern bikes with gears. Pull the chain through the rear derailleur. For example, 9-speed drivetrains require 9-speed chains, and so on. You should also make note of the type of drivetrain you have, as this determines which chains are suitable. Ideally, you want to buy a replacement chain that's the exact same length as the chain you had before (though bikes with a rear derailleur allow a small margin of error), so now is a good time to count the links in your chain. Once you've introduced a break in the chain, simply turn the pedals to pass the broken chain through the bike's gears.Don't push the pin all the way out, as they're quite hard to replace. If you want to reuse your chain, make sure you only push the pin far enough out of the way that the 2 links can be separated. To use a standard chain tool, simply line up one chain link in the tool's internal groove, securing it on the tool's "teeth", then turn the chain tool's handle to drive the tool's point down and push the pin out of the chain.If the chain is still holding together, you may need to introduce a break in the chain so that it's easier to remove. If the chain has completely split, simply turn the pedals until the length of the chain has passed around the sprocket and can be removed. If you've decided that your chain will be easier to replace than to repair, the first thing you'll need to do is get rid of the old chain. Older, more traditional chains have uniform pins, any of which can be used to repair a breakage (provided you have a chain tool with you). If this link is broken, you may need to wait until you can replace it to be able to repair the chain. These chains have a special link with 2 pins that is used to join the 2 ends of the chain. If you don't carry these special pins with you when you go riding, you may be out of luck in terms of repair options until you can make it to a bike shop. These chains require a special type of pin from the manufacturer (usually provided when you buy the chain) to repair a break. Most bike chains fall into one of 3 categories: X Research source For most bike chains, each link is connected to the next by passing a metal pin through the outer "plate" portion of one link and through the inner "roller" portion of the adjacent link. If the chain has fallen off completely, then you can just start to put on the new chain. If the chain is hanging loosely from the sprocket, then it should be easy to find the 2 separated ends of the chain. If the chain is still on your bike, then look for the break in your chain. Stop and lay your bike on its side with the sprocket up. Assess the damage and attempt a repair if possible. ![]()
