How long is a standard bike chain?

Narrower 3/32” chains are available for weight-shaving racers, as are more heavy-duty 3/16” chains, but for most riders the standard is fine. Chains are sold in standard lengths of 96, 98 or 112 links so you will need to use a chain tool to get it the right size for your drivetrain before installation.

What chain length do I need?

After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more.

How can I tell if my bike chain is stretched?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

What is a chain stay?

What is the chainstay? The chainstay or “stays” = The pair of frame tubes that joins the bottom bracket shell to the rear axle holders (the slots the back wheel goes in). This means that the chain stays connect the bottom bracket (BB) to the center of the back wheel.

How do I know if my chain is too short?

You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.

Do I need to shorten my bike chain?

Why Shorten a Bike Chain? All bikes come with a recommended bike chain length. It’s important to stick to this length if you want to ride comfortably and preserve the life of the rear derailleur. It’s the bike chain that does the work of getting the tires in rotation so that your bike can get in motion.
