Choosing a compound bow string is a complex process that requires careful consideration of several factors. The type of bow string, length, number of strands, and materials used all play a crucial role in the performance and accuracy of your compound bow.
Firstly, you need to decide between custom strings and stock bow strings. Custom strings offer better accuracy and performance but may invalidate your bow's warranty. On the other hand, stock strings are mass-produced and may not provide the same level of performance, but they are suitable for casual archers.
The length of the string is another important factor and depends on the riser length, idler wheel diameter, cam circumference, and the shape of the limbs. It is recommended to follow the manufacturer's specifications for the ideal string length.
The number of strands affects the speed of the arrow, with a lower number of strands resulting in higher speeds but potential vibrations and tuning issues. The type of material used for the string is also significant, with popular options including 8190, Dyneema, 452x, and Ultra-Cam, each offering different performance characteristics.
Lastly, proper maintenance and storage of your compound bow string are crucial for optimal performance and safety. Regularly waxing the string and storing it in a climate-controlled environment can extend its lifespan and improve its durability.

Custom vs stock strings
When choosing a compound bow string, there are two types to choose from: custom strings and stock bow strings.
Custom strings are designed to meet the demanding preferences of professional archers. They offer better accuracy and performance, as well as improved bow stability. However, they can be more expensive and may invalidate your bow's warranty.
Stock strings, on the other hand, are the ones that come preinstalled when you first buy your bow. These are mass-produced and usually don't have any special features. The quality can vary depending on the brand of bow. While stock strings may be sufficient for casual archers, competitive archers or hunters will likely want to opt for custom strings to ensure top performance.
When choosing a custom string, you can select from a variety of materials, colours, and strand counts to suit your specific needs. Custom strings are made-to-order, ensuring a perfect fit for your bow. However, this also means that you may have to wait longer to receive your custom string.
In contrast, stock strings are readily available and can be purchased off-the-shelf. They are typically more affordable than custom strings, but may not provide the same level of performance and accuracy.
Ultimately, the decision between custom and stock strings depends on your specific needs and budget. If you are a competitive archer or hunter, custom strings are likely the best choice to ensure optimal performance. However, if you are a casual archer or just starting out, stock strings may be sufficient and can save you money.

Bow string maintenance
The bowstring is the engine that drives your bow, so it's important to keep it well-maintained. Here are some tips to help you keep your bowstring in good condition:
- Waxing: The simplest way to maintain your string is to wax it regularly. The frequency of waxing depends on various factors such as humidity, how often you shoot, and the presence of dirt. As a rule of thumb, your string should always feel slightly tacky to the touch. If it feels slick and dry, it's time to wax it. Apply wax by rubbing it up and down the string with a stick, and then use your thumb and forefinger to melt it in. Do not apply wax to any serving material, as it can cause separation.
- Serving Inspection: Inspect the serving on your strings and cables. Serving is the thread that's tied over the top of the string. Look for any separation in the serving, especially in the nocking area, as it can affect accuracy. If you notice any issues, take your bow to a local archery pro shop for repairs or learn how to do it yourself.
- String Stretch: Recurve archers should regularly measure their bow's brace height to check for string stretch. Over time, the brace height can shrink if the string stretches. If this happens, unstring the bow and add twists to increase the brace height. For compound bows, check the cam timing to determine if there's been any stretching of the cables. Adjust the cables as needed to keep the cams synchronised.
- Storage: Store your bow in a climate-controlled setting to avoid stretch and prolong the life of your bowstring.
- Replacement: Even with proper care, bowstrings will eventually wear out. Most bow techs recommend changing strings at least every three years. However, if you notice any signs of wear, such as frays or broken strands, get it checked by a professional.

Waxing
The timing of when to wax your bowstring depends on several factors, including humidity, frequency of use, and the presence of dirt. As a general rule, you should be able to touch your string and feel a slight tackiness. If the string feels slick and dry, it's time to wax it. You may also notice “hairs” or fuzz sticking out from the strands of the bowstring, which is another indication that it's time to wax.
- Start by ensuring your bowstring is clear of any dirt or debris. Wipe it down with a clean, dry cloth or use a scrap piece of bowstring serving material to remove dirt and old wax.
- Apply wax directly to the length of the string by rubbing it up and down. Ensure that the wax is visible along the length of the strands. Do not wax the servings as it will unravel quicker and make it slippery.
- Use your fingers or a piece of leather to massage the wax into the string. The heat and friction will help melt the wax, allowing it to penetrate each individual strand and cover the entire string.
- Use a fabric cord, leather, or a flexible card to wrap around the string in a loop. Push the loop up and down the length of the string to even out the spread of wax. This will push the wax into the strands and remove any excess.
- Finally, remove any leftover lumps or excess wax with your fingers.
It is important to note that you should not over-wax your string as it can affect performance. Regular waxing will help your string last longer and perform better, especially if your bow is older and used frequently.

Number of strands
The number of strands in a compound bow string is an important consideration when choosing a string for your bow. The number of strands will impact the speed of your arrow, with a lower number of strands generally resulting in higher arrow speeds. However, fewer strands may also lead to increased vibrations and difficulties tuning your bow. Therefore, it is important to consider the trade-off between speed and stability when selecting the number of strands for your compound bow string.
Compound bow strings typically have between 20 and 24 strands. It is crucial to follow the manufacturer's recommendations for the number of strands, as using too few strands can cause significant vibrations throughout the bow, potentially damaging your equipment and leading to injuries. The number of recommended strands is based on your bow weight, with lower draw weights typically requiring fewer strands.
If you choose a lower strand count for your string, consider adding string silencers or dampeners to help reduce vibrations. Additionally, regular maintenance and proper storage of your bow string are essential to ensure optimal performance and longevity. Waxing your bow string regularly and storing it in a climate-controlled environment can help extend its life.
When ordering a new bow string, be sure to provide the make and model of your bow, as well as the string length and cable length specifications. Custom-fitted bow strings are tailored to your specific bow, ensuring the best quality and performance. By replacing your bow string regularly and choosing the appropriate number of strands, you can optimise your bow's performance and maintain consistency in your shooting.

Bow storage
Compound bows are designed to be left strung indefinitely. However, the string is under extremely high tension even at rest, and the bow should be stored in a safe place, out of reach of children. The storage area should be dry, dust-free, and free from excess heat.
There are several ways to store a compound bow:
- Hanging the bow on the wall: This is a simple method for temporary storage. Hang the bow by its cam or limb, not by the string, as this can cause unnecessary stress and strain. Keep the bow out of reach of children.
- Using a compound bow rack: Bow racks offer better storage than wall hanging. Purchase a rack that is designed for your specific bow. Ensure the string is not strained and keep the rack high on the wall.
- Storing in a bow cabinet: This provides added security and control over the environment. You can hang the bow or place it on a rack inside the cabinet.
- Using a hard bow case: A hard case provides the best protection and is ideal for travelling. It will protect your bow from harsh conditions and can be locked for security.
- Using a soft bow case: This option is lightweight and easier to carry. The foam compartment provides safety during storage and it can also be locked.
To maintain your compound bow, the string should be regularly waxed to maintain its moisture level and prevent fraying. The pulleys and cams should be oiled for permanent storage. Check the bow frequently to ensure that the rotating parts are not rusting or becoming stiff.
