Impact. Chains, like anything else on your bike, can be damaged if it gets hit hard enough. While not as common,

chains can break if they are involved in a rock strike or other impact

. Impact damage to chains can be more difficult to repair than if the chain breaks due to wear.

Are bike chains supposed to be tight?


It should be tight enough that it only allows you to move it up and down about one inch

. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur. Derailleur is the gear changing mechanism towards the back of the bike.

Do bike chains actually stretch?

Do bicycle chains really stretch? The short answer is

no, however they do wear in such a way as to cause their maximum length to increase

. Mechanics usually refer to this as chain “stretch.” It is the sign of a worn out chain that should be replaced.

How often do bicycle chains break?

Most mechanics agree that you should replace your chain about

every 2,000 to 3,000 miles

, depending on your riding style. Many Tour De France riders wear out two or even three chains on their primary bike over the course of the three-week race.

How do you break-in a chain?

How much do bike chains stretch?

The number most commonly agreed on for a worn chain is

one percent elongation between links

. In reality though, you want to replace the chain before this point. So therefore anything past 12, 1/16 inches (0.5 percent) would be the time to replace a chain.

How do you check if your 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

.

How long should a bike chain last?

So, how long do bike chains last? In general, a good chain will last

2,000 to 3,000 miles or 3 to 4 years

. Chains on mountain bikes and electric bikes will get worn out faster. Many factors can influence chain life, such as conditions, speed, weight, and stress.

What happens if my chain is too loose?

The major symptoms of a loose chain include chain teeth skipping over the sprockets, uneven transmission of power to the wheel leading to jerky wheel movements, chain lash and the chain slapping the swindle arm, and in the final case, chain coming off the sprocket.

How do you check bike chain tension?

What happens if your 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.

Do bike chains break easily?

Chains, like anything else on your bike, can be damaged if it gets hit hard enough. While not as common,

chains can break if they are involved in a rock strike or other impact

. Impact damage to chains can be more difficult to repair than if the chain breaks due to wear.

Why do I keep breaking bike chains?

Chains usually break because of

wear and bad shifting (under load)

. Either way I think you should buy a new chain and start again.

How much strength does it take to break a chain?

As it turns out, the European ISO standard of

8,000 Newtons

of minimum breaking force for a chain offers a good margin of security.

How long does it take for a bike to break-in?

A new motorcycle’s breaking-in period lasts for

about the first 500 – 1000 miles on the road

. This procedure is typically what manufacturers and enthusiasts call the technique for operating the bike when it is new.

Do you have to break-in a bike?


Your owner’s manual likely recommends a 600-, 1,000-, or even a 1,500-mile break-in process

where you limit throttle angle and revs, and constantly vary engine speed so that all those new internal components can get to know each other. For a new-bike owner, it’s a slow, grueling march toward your first service.

What is the speed limit for new bike?

We recommend an average speed of

60-80 kmph

for riding a new bike before the first service of the vehicle as the new engine takes time to cop-up with the driving style and condition. This speed maintains the health of a vehicle and results in a good performance for a longer duration.

How do you break a bike chain?

How do you break an old bike chain?

How do you break a bike chain without a tool?

How often should I lube my bike chain?

Bicycle Tutor recommends cleaning and lubricating your bike’s drive chain

at least once every month

to maintain optimal performance and protection. The chain and drivetrain are typically the dirtiest parts of your bike, and this dirt is bad news for bike longevity and performance.

How many links should a bike chain have?

A new bicycle chain usually comes with

116 links

. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.

How long does a chainring last?

A steady rider who stays on the big ring, keeps the drivetrain clean and doesn’t let the chain get too long before replacing it, and started with good quality components can get

60,000+ miles

out of a chain ring.

Are bike chains universal?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However,

this does not mean all makes and models of chains are interchangeable

.

Are all bike chains the same?

Are all bicycle chains the same size?

No, all bicycle chains are not the same size

. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.

How can you tell a real Shimano chain?

  1. old packaging — chains in packaging that doesn’t look like current stuff is not likely to be ‘new old stock’, it’s just fake.
  2. wrong packaging.
