INSTALLATION AND USING

The chain  spoket, as a drive or deflection for chains, has pockets to hold the chain links with a D-profile cross section with flat side surfaces  parallel to the centre plane of the chain links, and outer surfaces at right angles to the chain link centre plane. The chain links are pressed firmly against the outer surfaces and each of the side surfaces by the angled laying surfaces at the base of the pockets, and also the support surfaces of the wheel body together with the end sides of the webs formed by the leading and trailing walls of the pocket.

NOTICE

When fitting new chainwheels it is very important that a new chain is fitted at the same time, and vice versa. Using an old chain with new sprockets, or a new chain with old sprockets will cause rapid wear.

It is important if you are installing the chainwheels yourself to have the factory service manual specific to your model. Our chainwheels are made to be a direct replacement for your OEM chainwheels and as such, the installation should be performed according to your models service manual.

During use a chain will stretch (i.e. the pins will wear causing extension of the chain). Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME).

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

bike sprocket

What are the signs of wear and tear in bike sprockets and how do I identify them?

Bike sprockets, also known as cassette sprockets or cogs, are an essential part of the drivetrain that can experience wear and tear over time. Regular inspection can help you identify signs of sprocket wear and determine when replacement is necessary. Here are the common signs of wear and tear in bike sprockets:

  • Hooked Teeth: Inspect the teeth of the sprockets. If you notice that the teeth have a hooked or shark fin-like appearance, it indicates significant wear. This occurs due to the chain wearing down the metal over time.
  • Pointed Teeth: Pointed teeth are another sign of wear, where the tops of the teeth become sharp and pointed instead of having a flat profile.
  • Worn Teeth: Look for flattened or thinned-out teeth, especially in the middle of the sprockets. Worn teeth can affect the chain’s engagement and lead to poor shifting performance.
  • Missing Teeth: If any teeth are completely missing from the sprocket, it’s a clear sign of excessive wear and a replacement is necessary.
  • Chain Skipping: When riding, if the chain skips or jumps over the sprockets, it indicates that the sprockets’ teeth are worn and no longer providing a smooth engagement with the chain.
  • Noisy Shifting: If you notice unusual noise during shifting, it could be due to the chain not meshing properly with the worn sprocket teeth.
  • Chain Elongation: Excessive sprocket wear can accelerate chain elongation, leading to further wear on the sprockets. If you notice your chain has elongated significantly, it’s time to inspect the sprockets for wear.

To identify these signs of wear, you can visually inspect the sprockets. You may need to remove the rear wheel and carefully examine the cassette or freewheel sprockets. Look for any irregularities in the teeth, and run your fingers along the tops of the teeth to feel for sharp points or rough edges.

Regular maintenance and cleaning of your bike’s drivetrain can help identify sprocket wear early on. By keeping the drivetrain clean, properly lubricated, and regularly replacing the chain, you can extend the life of your sprockets and other drivetrain components.

If you notice any of these signs of wear, it’s best to replace the worn sprockets promptly. Replacing sprockets before they become excessively worn can help maintain smooth shifting performance and prolong the life of the entire drivetrain.

How do I prevent chain slippage and skipping issues with bike sprockets?

Chain slippage and skipping can be frustrating and potentially dangerous while riding a bicycle. However, there are several preventive measures and maintenance practices that can help minimize these issues:

1. Chain Lubrication:

Regularly lubricating the chain is crucial to reduce friction and wear. Use a bicycle-specific chain lubricant and apply it to the chain links evenly. Wipe off any excess oil to prevent attracting dirt and debris that can contribute to skipping.

2. Chain Cleaning:

Keep the chain clean by regularly removing dirt and grime. Use a chain cleaning tool or a rag soaked in a degreaser to clean the chain thoroughly. Clean chains operate more smoothly and are less likely to skip.

3. Chain Tension:

Proper chain tension is essential for smooth shifting and reduced skipping. If your bike has a derailleur, follow the manufacturer’s guidelines for setting the correct chain tension. In the case of single-speed or internally geared bikes, ensure that the chain tension is appropriately adjusted.

4. Sprocket and Chainring Inspection:

Regularly inspect the sprockets and chainrings for wear. Worn-out teeth can cause chain skipping. Replace any sprocket or chainring that shows significant signs of wear, such as shark-fin-shaped teeth or sharp points.

5. Chain Replacement:

Chains naturally wear out over time, and a stretched chain can lead to skipping issues. Replace the chain before it becomes excessively worn to prevent premature wear on the sprockets.

6. Proper Shifting Technique:

Shift gears smoothly and avoid putting excessive pressure on the chain while shifting. Make sure to ease off the pedals momentarily when shifting to allow the chain to move smoothly between gears.

7. Regular Maintenance:

Perform routine maintenance on your bike, including checking the drivetrain components, cable tension, and derailleurs. Regular maintenance can help identify potential issues before they become major problems.

8. Avoid Cross-Chaining:

Avoid extreme gear combinations known as cross-chaining, such as using the largest chainring with the largest sprocket or the smallest chainring with the smallest sprocket. Cross-chaining can stress the chain and cause skipping.

9. Wheel Alignment:

Ensure that the wheels are properly aligned in the dropouts. Misaligned wheels can lead to poor chain tension and alignment, affecting shifting performance.

By following these preventive measures and conducting regular maintenance, you can significantly reduce the risk of chain slippage and skipping issues with your bike sprockets, ensuring a smoother and more enjoyable ride.

What is a bike sprocket, and what is its role in a bicycle’s drivetrain?

A bike sprocket, also known as a bicycle sprocket or chainring, is an essential component of a bicycle’s drivetrain system. It plays a crucial role in transferring power from the cyclist’s pedaling to the wheels, propelling the bike forward. The sprocket is mounted on the crankset, which is attached to the bicycle’s pedals.

Construction and Function:

A bike sprocket is typically a flat, circular disc with teeth around its outer edge. These teeth mesh with the links of the bicycle chain. The number of teeth on the sprocket determines its gear ratio, affecting how much rotational force is transferred to the bike’s rear wheel.

Role in the Drivetrain:

When a cyclist pedals, the chain moves along the sprocket’s teeth, creating a rotational force. This force is transmitted to the rear sprockets (cassette) through the bicycle chain. As a result, the rear wheel’s rotation is controlled, and the bike moves forward. The different-sized sprockets on the front crankset and the rear cassette provide multiple gear options, allowing the rider to adjust the bike’s mechanical advantage according to the terrain and riding conditions.

Smaller sprockets with fewer teeth are used for easier pedaling and climbing hills, providing more mechanical advantage. On the other hand, larger sprockets with more teeth are used for higher speeds and flats, enabling the bike to cover more ground with each pedal stroke.

Gearing and Gear Ratios:

Bicycles may have single-speed drivetrains with only one front sprocket or multiple speeds with multiple front and rear sprockets. The combination of the front sprocket and the selected rear sprocket determines the gear ratio, affecting the bike’s speed and torque. Cyclists can switch between gears using the bicycle’s shifters to find the most efficient gear for their pedaling cadence and the terrain they are riding on.

The bike sprocket is a fundamental part of the bicycle’s drivetrain, providing the mechanical advantage necessary for efficient and comfortable riding. Proper maintenance, such as regular chain lubrication and periodic sprocket inspection, is essential to ensure smooth gear changes and extend the sprocket’s lifespan.
