Bike Chain 1/2 x 1/8 With 112 Links for Single Speed Bikes

Is your bicycle chain worn, rusty, stretched or no longer running smoothly? This bike chain 1/2 x 1/8 is made for single speed bikes, city bikes, Dutch bikes, transport bikes and bicycles with coaster brakes. The chain has 112 links, an 8.6 mm width and includes a connector link, making it a practical replacement when you want to replace a bike chain yourself.

This classic bike chain 1/2 x 1/8 with 112 links is suitable for bicycles without derailleur gears. It is commonly used on everyday city bikes, Dutch-style bikes, transport bikes and single speed bicycles. It is not designed for modern derailleur bikes with several rear sprockets, because those usually require a narrower chain size.

At Discountershop, this product is part of the bicycle accessories and bicycle parts range for regular maintenance. It is suitable for customers who want to buy bike chain products with clear technical sizing and no guesswork.

Technical Chain Size: What Does 1/2 x 1/8 Mean?

The size 1/2 x 1/8 is the most important detail when choosing the right bicycle chain. The first measurement, 1/2 inch, refers to the chain pitch: the distance between two chain pins. The second measurement, 1/8 inch, refers to the inner chain width. This width is commonly used for single speed sprockets and rear cogs on bicycles without derailleur systems.

Which Bikes Is This Bicycle Chain Suitable For?

This chain is designed for bicycles without a derailleur. It mainly fits bikes with one gear or a coaster brake system. That makes it suitable for many daily-use city bikes used for commuting, school, shopping and short local rides.

Suitable for:

• City bikes
• Dutch bikes
• Transport bikes
• Single speed bicycles
• Bicycles without gears
• Bicycles with coaster brakes
• Many bikes with a closed chain guard

This chain is a good match when you are looking for a city bike chain, cheap bike chain or bike chain online for a standard everyday bicycle. For an e-bike chain, always check the drivetrain first. This chain may only fit an e-bike if it uses a single speed drivetrain with 1/2 x 1/8 chain sizing. E-bikes with derailleurs, special mid-drive chainlines or multiple gears usually need a different chain.

When Does This Chain Not Fit?

Not every bicycle uses the same chain. That is why bike chain sizes matter. A 1/2 x 1/8 chain is wider than many derailleur bike chains. Do not use this chain on a bicycle with 6, 7, 8, 9, 10, 11 or 12 rear gears unless the bike manufacturer confirms this exact chain size.

Usually not suitable for:

• Road bikes with derailleurs
• Mountain bikes with multiple gears
• Hybrid bikes with derailleurs
• E-bikes with derailleur gears
• Bikes using a narrow 3/32 inch chainline
• Modern speed pedelecs without confirmed compatibility

If you are looking for a mountain bike chain, first check whether your mountain bike is actually single speed. Most mountain bikes have derailleur gears and use a narrower chain. For different bicycle chains, always choose by chain size, number of gears and sprocket width, not only by bike type.

When Should You Replace Your Bike Chain?

A worn chain can cause noise, poor power transfer, skipping, rough pedalling and faster sprocket wear. On a single speed bike, chain wear is often visible through a loose chain, skipping under pressure, rust, stiff links or a chain that needs repeated tension adjustment.

Replace your chain when:

• The chain is visibly rusty or dry
• Links remain stiff after lubrication
• The chain skips on the sprocket
• The chain has stretched too far
• Pedalling feels uneven
• The chain guard makes noise while riding
• The old chain has damaged or bent links

Regular maintenance can make your bike cheaper to run because a worn chain can also damage the rear sprocket, front chainring and chain guard. Replacing the bicycle chain on time helps prevent extra repair costs.

How to Install This Bicycle Chain

This bicycle chain includes a connector link, which makes installation easier than closing a chain with a fixed chain pin. In most cases, you will need a chain tool to shorten the chain to the correct length. On some city bikes, the chain guard may also need to be opened partly.

Installation steps:

1. Position the Bike Safely

Place the bike securely on its stand or in a repair stand. Make sure the rear wheel can move freely. Wear gloves if possible, because old chains often contain grease and dirt.

2. Remove the Old Chain

Find the connecting link or use a chain tool to open the old chain. Pull the chain carefully away from the front chainring and rear sprocket. Check the sprockets immediately for sharp teeth, bending or heavy wear.

3. Compare the Chain Length

Place the old chain next to the new chain. If the old chain had the correct length, shorten the new chain to the same number of links. Keep in mind that an old chain may be stretched, so counting links is more accurate than comparing physical length only.

4. Shorten the Chain if Needed

This chain has 112 links. Some bicycles may need fewer links depending on frame size, rear wheel position and sprocket combination. Remove extra links with a chain tool. Work carefully to avoid damaging the side plates.

5. Place the Chain on the Sprockets

Lay the chain over the front chainring and rear sprocket. Check that the chain runs straight and is not twisted. If the bicycle has a closed chain guard, this step may take a little more time.

6. Close the Connector Link

Attach the connector link to both chain ends. Pull the chain tight enough for the link to lock correctly. Then check by hand that the connector link is seated properly and runs smoothly through the drivetrain.

7. Adjust Chain Tension

On a city bike with coaster brake, chain tension is often adjusted by moving the rear wheel slightly backward or forward. The chain should not be tight like a belt, but it should also not hang too loose. A small amount of vertical movement is normal.

8. Test Before Riding

Turn the pedals slowly by hand. Check that the chain runs smoothly, does not skip and does not rub against the chain guard. Test the coaster brake carefully before using the bike normally again.

Why Choose This Chain?

When you want to buy bike chain products online, correct sizing is more important than a long product name. This chain is specifically made for single speed use and includes the required connector link. That makes it suitable for many standard bicycles without derailleur gears.
