When Should You Replace Your Bow Strings - And How to Make Them Last Longer

Bow strings don't just quit on you all at once. They wear out slowly, over hundreds of shots, over seasons, until one day your bow won't stay in tune, your peep won't stay put, and you're pulling your hair out trying to figure out what's wrong — when the strings have been the problem the whole time.

Let's break it down. When do you actually need to replace them, what should you be looking for, and how do you get the most life out of a set once you've got them on?

How Often Should You Replace Bow Strings?

For most people, the answer is every two to three years.

I know what you're thinking — you know a guy who's had the same strings on his bow for a decade and he'll tell you it shoots just fine. And maybe it does. But when old strings fail, they don't just go a little sideways. It's typically a bomb. We're talking catastrophic. Not the kind of thing you want to find out mid-draw on an animal.

Beyond the risk of failure, worn strings just don't perform. They lose consistency. You'll start chasing your tune, fighting your peep, losing poundage — all signs the strings are past their prime. Two to three years is the sweet spot for keeping your bow shooting the way it's supposed to.

Signs Your Bow Strings Need to Be Replaced

Excessive Flyers

This is the most obvious one. Look at your string and cables — if you see little pieces of thread just hanging off, fluffy and frayed all over the place, that's not something wax is going to fix. When the fibers start breaking down like that, it's time. Everything has a shelf life, and strings are no different.

Serving Separation

Look at the serving — the wrapped section around your cam, around your center serving, and around any cable guards or slides. If you can see separation where the actual string fibers are exposed underneath, that's your cue.

You can re-serve it yourself if you've got the capability. But if the string is already a few years old, you're better off just replacing the whole set. Once serving starts separating at the center, your nock fit gets inconsistent, and inconsistent nock fit means inconsistent arrows. And at the cable guard area, exposed string fibers are going to wear fast and eventually fail.

Peep Won't Stay Put

New strings rotate — that's normal while they're settling. But excessive peep twist on a seasoned set? That's a worn-out string. If you've adjusted it, twisted it, done everything right and that peep still won't stay aligned no matter what you do — the string is telling you it's done.

Bow Coming Out of Time or Losing Poundage

If your cams aren't rolling over in sync or you're consistently losing draw weight, the strings are the first place to look. A bow that was tuned perfectly and keeps falling out of tune isn't a tuning problem — it's a string problem. When the material breaks down, it stops holding the tension and geometry the bow needs to function right.

The Feel Test

This one gets overlooked. Run your hand down a fresh set of strings — there's a shine to them, a smoothness. Now feel a set that's been on a bow for three seasons. They get gritty, dry, almost rough. When you start feeling that and seeing the flyers come with it, there's only so much waxing you can do before you're just prolonging the inevitable.

How to Extend the Life of Your Bow Strings

Here's where most guys go wrong — they wax too much.

I get it, the thinking is more wax equals more protection. But what actually happens is you build up a thick layer of wax on there that collects dust, dirt, and debris. That gunk gets worked into the string fibers and it acts like sandpaper on them from the inside out. You're literally accelerating the wear.

The move is to wax only the string fibers — not the serving. Use a silicone-based wax, apply a thin coat, and rub it in. Less is more. You don't need a thick buildup. Just enough to keep moisture in the fibers and protect them from the elements.

If you've already over-waxed your strings, you can actually strip them down. Use dental floss and work it back and forth along the string to pull off the excess wax and built-up grime. Get it clean, then put a fresh thin coat back on. That alone can add life to a set that was getting wrecked by wax buildup.

Inspect the Whole Bow — Not Just the Main String

When you're doing your string check, don't just look at the main string and call it good. You need to go through the whole bow.

Look at the cables. Check the yokes. Inspect every point of contact — anywhere the string or cable runs across hardware, through a guide, or wraps around a cam. Those are the spots where wear happens fastest.

Pay close attention to where your peep is installed. Any nicks in the fibers from when the peep was put in, any flyers concentrated in that area — that's a failure point. Same with the yokes. If you see exposed raw fibers and fraying on the yoke, that bow needs a new string set before it goes back out.

Don't wait until it fails on you in the field.

Bottom Line

Two to three years. That's your window for most setups with regular use.

Wax your strings right — silicone based, on the fibers only, thin coat — and inspect the whole setup at least a couple times a season. Catch the warning signs early and you'll never get caught off guard.

If you're not sure whether your strings need to go, bring your bow into the shop and we'll take a look at it. Better to know now than to find out the hard way during season.
