When should I shorten my bike chain?

Do I need to shorten my bike chain?

Unless of course you’re running singlespeed, then yes, you need to shorten the chain. Strictly, and assuming the chain was the correct size, yes. … You can only shorten a chain by a whole link, which is two teeth’s worth of chain, so if the chain was optimal before you could make it too short.

How do I know if my bike 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.

What length should my bike chain be?

In order to make absolutely sure the chain is long enough, it should be put around the biggest chainring in the front, the biggest sprocket at the rear and then add one more inch, or one link because of the derailleur.

Can a bike chain be too long?

Too much chain is kind of annoying, but too little can break things. Trying to shift into the large-large gear when there’s not enough chain will stop your pedals, so there’s a lot of force involved. Since you’re going into a lower gear at that point, it often happens when you’re pedalling hard.

Twenty half-links in a new chain measure 10 inches (254 mm), and replacement is recommended before the old chain measures 10 1⁄16 inches (256 mm) (0.7% wear). A more conservative limit is when 24 half-links in the old chain measure 12 1⁄16 inches (306 mm) (0.5% wear).

What happens if bike chain is tight?

When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. Ultimately, a tight chain on a motorcycle may break leaving you with no power.

How do I know which bike chain to buy?

When selecting a chain, the first consideration is the number of rear sprockets. The rear cog sets have been made with 5, 6, 7, 8, 9, 10, 11, or 12 sprockets. As the number of cogs on the rear hub increases, the spacing between cogs tends to be reduced.

How do you calculate chain length?

Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.

What is chain length chemistry?

For any chemical chain reaction, the chain length is defined as the average number of times that the closed cycle of chain propagation steps is repeated. It is equal to the rate of the overall reaction divided by the rate of the initiation step in which the chain carriers are formed.
