How to Choose a Bowstring (String & Cable Set)
Replace worn strings before they fail. Learn material types, strand count, served peeps, and break-in so your bow shoots accurately and safely.
How Coach Rob judges it
These are the things that actually decide the right answer for you. Every recommendation is weighed against them.
- Wear signs and replacement timing
- A string that looks fine can still be overdue for replacement. Check for fuzzing or fraying in the served areas, peep rotation under draw, serving separation near the cam or nocking point, and any discoloration from dry-firing. Most compound strings benefit from annual replacement in a high-volume shooting schedule, or every two to three seasons for recreational archers.
- Factory vs. custom strings
- Factory strings ship with the bow and are engineered to spec, which makes them a reliable starting point. Custom strings are hand-built to tighter tolerances, often with premium fiber, and tend to hold their tune longer once broken in. For casual shooters, a quality factory replacement is usually sufficient; competitors or anyone shooting daily will notice the difference a custom set makes over a full season.
- String material category
- Modern bowstring fibers fall into a few broad categories: low-creep materials that prioritize stability and minimal stretch after break-in, and slightly more elastic fibers that offer a softer draw feel and more forgiveness. Neither category is universally better. A stability-focused fiber suits a tuned competition setup; a more forgiving fiber can benefit beginners still developing consistent form. Ask your pro shop which category matches your bow's cam timing and your shooting goals.
- Strand count and its effect
- More strands mean a heavier string that generally absorbs more vibration but adds a small amount of mass to the string, which affects arrow speed. Fewer strands produce a lighter, faster string at the cost of some durability. Manufacturers specify a strand-count range for each bow model; staying within that range matters more than chasing the lightest or heaviest option. Your pro shop or the manufacturer's chart will point you to the right range for your draw weight.
- Compound cable sets vs. recurve strings
- A compound bow has a string and one or two cables that all wear at different rates. Replacing only the string and leaving worn cables throws off cam lean and timing, which undoes any tuning work. Always replace the full set together. Recurve strings, by contrast, are a single loop with no cables, so the decision is simpler: match the correct AMO length and strand count to the bow's limb rating, and choose a fiber that suits your shooting volume.
- Break-in, stretch, and wax maintenance
- New strings need to be shot in before the bow can be paper-tuned reliably. Shooting several dozen arrows allows the fibers to settle, after which the bow will need a draw-length and draw-weight check. Once broken in, regular waxing keeps the fibers from drying and fraying, extends string life, and helps maintain consistent performance. Wax the string body, not the servings, and use a wax formulated for bowstrings rather than a generic product.
The short answer
Match the string and cable set to your bow’s specifications, choose a fiber category that fits your shooting volume and goals, and replace the full set before wear becomes a reliability issue. A bowstring is not a set-and-forget component. It stretches, frays, and loses its tune over time, and catching that decline early keeps your setup accurate and safe.
When to replace: the signs that actually matter
Most archers replace strings on a schedule rather than in response to what they see, which is not necessarily wrong, but visual inspection still matters between replacements. Fuzzing along the string body, particularly in the served areas around the cam and at the nocking point, is the clearest sign that fiber integrity is declining. Serving separation, where the wrapping peels away from the underlying fiber, exposes the string to accelerated wear at its highest-stress points.
Two less-obvious indicators are peep rotation and creep. If a served-in peep is rotating out of alignment when you draw, the string has stretched unevenly and the strands have lost their original balance. Creep shows up as a gradual change in draw length or draw weight over weeks of shooting. Both mean the string has done most of its useful life.
If you dry-fire a bow by accident, bring it to a pro shop before shooting it again. Dry-firing puts enormous stress on the string and cam system in the fraction of a second that would normally be absorbed by an arrow’s mass.
Factory strings versus custom sets
A factory replacement string is built to the bow’s specification and will get you shooting reliably. For recreational archers who shoot a few times a week, a quality factory string replaced on a reasonable schedule is a practical choice.
Custom strings are hand-served by a builder who selects fiber, sets strand count, and installs servings with more precision than mass production allows. The result is a string that tends to creep less during break-in, holds peep alignment more consistently, and stays in tune longer. Competitive archers and anyone shooting daily will notice the difference across a season, especially in how seldom they need to re-tune.
The price gap between factory and custom has narrowed. If you are already making regular shop visits for tuning, the longer tune life of a custom set can offset some of that cost.
String material: what the categories actually mean
You will hear fiber names discussed in terms of their stretch characteristics. Low-creep fibers are the current standard for compound bows because they settle quickly after break-in and remain dimensionally stable over temperature changes and high draw weights. Once a low-creep string is shot in, it tends to stay where it was tuned.
Higher-elongation fibers feel softer through the draw and are more forgiving of slight inconsistencies in form. Some traditional and recurve shooters prefer this characteristic. For compound shooting at higher draw weights, though, elongation becomes a liability because it makes consistent timing harder to maintain.
Neither category is universally superior. The right choice depends on your bow, your draw weight, and how much tuning time you are willing to invest. A pro shop can tell you what fiber category your cam timing is designed around.
Strand count: what to know without chasing specs
Strand count affects string weight, durability, and feel, but the practical guidance is simpler than it sounds. Your bow manufacturer publishes a strand-count range for a reason: too few strands reduces durability and can create uneven cam load, while too many adds mass that reduces speed and can change the string’s dynamic at full draw.
Stay within the manufacturer’s recommended range. Within that range, archers at higher draw weights typically choose toward the higher strand count for durability; target archers focused on speed sometimes choose toward the lower end. If you are not sure where to land, your pro shop can advise based on how you shoot.
Served-in peeps and d-loops: get them right at installation
A peep sight and a d-loop are both installed during the serving process, and how they are installed matters as much as what you buy. A peep that is served in under the wrong amount of tension will rotate under draw, which makes consistent aim nearly impossible and indicates the string is not properly balanced. A properly installed peep should align without effort at your consistent anchor point.
D-loops wear faster than the string itself because they absorb the mechanical stress of the release aid every shot. Inspect the loop for nicks, fraying, or asymmetric wear regularly. Replacing a d-loop is inexpensive and straightforward at a pro shop, and a fresh loop eliminates one variable when you are troubleshooting inconsistent groups.
Break-in and ongoing maintenance
A new string is not ready to tune against immediately. The fibers need to be shot in, typically through several dozen arrows, before they settle into a stable configuration. During this period the bow’s draw length and draw weight will shift slightly. After break-in, confirm those measurements before paper-tuning.
Waxing extends string life and maintains fiber cohesion. Apply a light coat of bowstring wax to the string body every few hundred arrows, or whenever the string looks dry. Work it in with your fingers to generate a little heat that helps the wax penetrate. Avoid waxing the servings, which are tightly wrapped and do not benefit from wax the same way the string body does.
Storage matters too. Strings left in a hot car or in direct sunlight for extended periods degrade faster than strings stored in a case at stable temperatures. It is a small habit that adds months of life to the string.
If you have any question about which string or cable set is correct for your specific bow model, bring the bow in. The cam geometry, draw weight, and existing serving setup all factor into the recommendation, and getting it wrong creates tuning problems that are harder to diagnose after the fact.
How do I know if my bowstring needs replacing?
Look for fuzzing or fraying anywhere along the string, especially near the servings. Peep rotation under draw and serving separation near the cam are two reliable signs the string has stretched unevenly and has lost its integrity. If you notice any of these, bring the bow in before shooting it further.
Does a custom string actually improve accuracy?
Not directly on its own, but custom strings typically hold their tune better over time because they are built with tighter manufacturing tolerances and higher-grade fiber. That consistency means your bow stays in tune longer between shop visits, which shows up as tighter groups through a full season of shooting.
Can I replace just the string and leave the cables?
On a compound, that is not recommended. The string and cables wear as a system, and mismatched wear introduces cam lean and timing errors that are difficult to tune out. Replacing the full set keeps everything working together and gives you a clean baseline for tuning.
How often should I wax my bowstring?
Wax whenever the string looks dry or you can see individual fibers starting to separate slightly, which for most shooters is every few hundred arrows. In dry or cold conditions you may need to wax more frequently. Apply wax to the string body and work it in with your fingers; avoid the servings, where wax can collect debris.
What length string do I need for my recurve?
Recurve string length follows the AMO standard: the string is typically a fixed amount shorter than the bow's AMO length, which varies by bow design. Check the bow manufacturer's specification for the correct string length and strand count. Buying the wrong length changes brace height and affects draw weight, so it is worth confirming before you order.
