How To Determine Correct Bicycle Chain Length?

How long of a chain do I need for my bike?

If your bike is equipped with the derailleur, you need a 3/32″ or 11/128″ chain. If you have a single-speed or internally geared bike, you need either 1/8″ or 3/32″. You should get the correct size, but if it is not possible, you can get the 1/8″ because it has limited compatibility with the 3/32″ sprocket.

How do I know if my bike chain is too long?

Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.

What is the chain length?

Why does my chain slip when I pedal hard?

Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.

How do I know if my chain is too loose?

75% of its original length. If you put the tool up against the chain and it doesn’t reach the 0.5 mark, then your chain has not elongated and is fine. If you find that it is 0.5, you need to replace the chain if you have 11 or more rear gears. If it is 0.75, you need to replace it if you have 10 or fewer rear gears.

Is my bike chain too short?

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. Before you remove the chain, make sure it’s on the small chainring and smallest cog.
