The Quiet Backbone of Every Crossbow Cocking Aid
Most crossbow hunters do not think much about the cord on their cocking rope or crank, right up until the moment it frays, slips, or snaps mid-pull. That is when you find out that the few feet of braided line doing the actual work of cocking your bow is not a luxury part. It is the part. The BCY Crossbow Cocking Cord 20 ft. is the replacement length BCY makes specifically for that job: a high-tenacity braided spectra cord rated for serious pulling loads, sold in 20 ft lengths so you can rebuild rope cockers, cranks, and aftermarket cocking aids without having to source string material from a custom shop.
If you cock a crossbow more than a handful of times per year, this is the kind of inexpensive part worth having on the shelf before you need it. We have customers who buy it twice a year and customers who buy it once and forget about it for three seasons. Either way, having a 20 ft length on hand turns a broken cord from a season-ending problem into a 10-minute repair.

One Replacement Cord That Saves Your Season
The honest reality of crossbow ownership is that the cocking aid sees more wear than almost anything else on the bow. Every shot starts with you putting a triple-digit load into that cord. Multiply that by a few hundred practice pulls per year, plus the in-field cocks during hunting season, and the cord gets compressed, abraded against rope hooks, and worked over the cocking groove until the braid starts to fuzz, fray, or twist.
Most factory rope cockers ship with a cord that is built for the same kind of life expectancy as any consumable string. After a season or two, the cord either visually starts shedding fibers, loses its smooth glide through the rope hooks, or develops a soft spot you can feel under load. The BCY 20 ft cord exists so you can pull off the old cord, cut a fresh length to fit your specific rope cocker or crank, attach your hooks or handles back on, and have a like-new tool again.
Why a 20 ft Length Earns Its Spot in the Shop Drawer
We carry a lot of crossbow accessories at Lotz Outdoors, and the cocking cord is one of those parts that quietly moves season after season because the math just works out in the customer's favor.
One purchase covers multiple repairs
A standard rope cocker uses around 4 to 5 ft of cord. A 20 ft length gives you four full rebuilds, or two rebuilds plus some leftover for backup. Even if you only use one or two of those lengths personally, the rest stays in the drawer for the next time, and 20 ft is far more economical than buying single-length pre-cut replacements.
Braided spectra holds up to crossbow loads
Spectra (ultra-high-molecular-weight polyethylene) is the same fiber family used in many high-end fishing lines and rope-rated marine cordage. It handles repeated high-tension pulls without stretching or creeping under load. For a tool that has to pull 100 to 300 lb of draw weight cleanly, that lack of stretch matters.
750 lb test rating gives real safety margin
You are not loading the cord to its breaking strength on every pull. You are loading it to roughly your bow's draw weight, which means the 750 lb rating leaves a meaningful safety margin even on the heaviest crossbows. That margin is what prevents the catastrophic failures that cheaper unrated cords can cause.
Smooth braid glides through rope hooks and pulleys
The braided construction is smooth enough to pass cleanly through standard rope hooks, S-hooks, and crank pulleys without binding. Rougher cord materials catch on the hardware, throw off your pull symmetry, and cause one side to cock the string ahead of the other.
Brand consistency from a known string maker
BCY has been in the bow-string business for decades. The material consistency from one length of cord to another is dependable, which matters because a rope cocker with cord variation pulls unevenly. A reliable supplier of the raw material removes one source of inconsistency.
Where the BCY 20 ft Cord Earns Its Keep
Mid-season rope cocker rebuild
You have been hunting for six weeks, you go to cock your bow on a cold morning, and the cord feels gritty as it slides through the hooks. That is the moment to swap it out, not the moment to keep pulling and hope it lasts. A pre-cut spare length in your kit means you can rebuild the cocker between sits and get back on the bow the same day.
Crank cocking aid replacement
Crank cocking systems use a longer length of cord that wraps around a winding drum. They burn through cord faster than hand-pulled rope cockers because of the wrap-and-unwrap cycle. The 20 ft length is sized to cover even the longest crank applications without scrimping.
Pre-season equipment audit
Smart crossbow owners go through every piece of cocking hardware before the season starts. The cocking cord is the most common failure point and the easiest to overlook because it looks fine until you put a hard load on it. A fresh cord installed in August pays dividends in October.
DIY custom cocking aid builds
Some hunters build their own simplified rope cockers from off-the-shelf hooks and handles. The BCY 20 ft cord is the input material for those builds and lets you size the cord exactly to your draw length and grip preference instead of accepting the factory length.
Pro shop repair work
Archery shops doing crossbow tune-ups and repairs go through cord regularly. Buying in 20 ft lengths is cheaper per rebuild than stocking individual pre-cut replacements, and the same material covers different makes and models of cocking aids.
Is the BCY 20 ft Cord the Right Replacement for Your Setup?
The 20 ft length is a strong fit if you own a crossbow with any kind of cocking aid (rope cocker, ACU cocker, or crank) and you would rather rebuild the cord yourself than mail the unit back to the manufacturer. It is also the right call if you maintain crossbows for friends or family and want enough cord on hand to fix several units without re-ordering. Hunters who hand-cock without an aid will not need this, although you should not be hand-cocking any modern crossbow over about 175 lb draw weight without a real reason.
Where the cord is not the right fix: if your cocking aid is structurally damaged (cracked handle, deformed hooks, stripped crank gears), replacing only the cord will not solve the underlying issue. Inspect the rest of the hardware before assuming a new length of cord brings the tool back to spec.
Common Questions About the BCY Cocking Cord
How long does one cord last in normal use?
Light recreational shooters get multiple seasons out of a single rebuild. Heavy practice shooters or pro shops doing demo pulls go through cord faster, sometimes once per season. The cord shows wear visibly (fraying, fuzzing, gloss loss) before it fails catastrophically, so visual inspection between hunts catches most problems early.
Will it fit my specific cocking aid?
The 20 ft length is intentionally generous. You cut to the length your specific rope cocker, ACU cocker, or crank requires. Standard rope cockers use roughly 4 to 5 ft. Crank systems typically use 6 to 12 ft depending on the model. Always measure your existing cord before cutting, and leave a few extra inches for terminations.
How do I attach my existing handles and hooks?
Most rope cockers terminate the cord with a knot through the handle ports or hook eyes. Common knot choices include a figure-eight stopper knot or a doubled overhand depending on the hardware geometry. Some hunters whip-finish the cut ends with serving thread or thin shrink tubing to prevent fraying before the knot.
Can I cut it cleanly without fraying?
Spectra braid wants to fray when cut with regular scissors. The cleanest cuts come from a hot knife, soldering iron, or even a hot kitchen knife held against the cord. The heat seals the braid ends and prevents the wisping that causes knots to slip later.
Will it stretch over time?
Spectra fiber is engineered to be minimally elastic, which is exactly why it is the right material for this job. You should not see meaningful stretch under normal cocking loads. If your cocker starts feeling soft or inconsistent, it is more likely cord wear, not stretch, that is causing the change.
Is the cord UV resistant?
The synthetic braid handles routine outdoor exposure well, but storing the cocking aid in a closed case between hunts will extend the cord's useful life. Long-term direct sun exposure (a season-long mount in a tree stand) will gradually degrade any synthetic line. Store hardware indoors during the offseason.
Does temperature affect it?
The cord performs consistently across the temperature range you will hunt in. Extreme cold makes the braid feel slightly stiffer but does not compromise strength.
A Tip From the Lotz Outdoors Bench
The biggest mistake we see is people waiting until the cocking cord visibly fails before they replace it. Inspect the cord between every multi-day hunt. Run it through your fingers and look for fuzzing, glossy spots that have flattened, or asymmetric wear at the rope hook contact points. If you see any of those, swap the cord at home, not in the field. A 10-minute rebuild in your shop beats trying to MacGyver a fix at 5 AM in a parking lot.
Second tip: when you cut a new length, seal the ends with heat before you tie your terminations. A clean, sealed end takes a knot cleanly and resists the slow loosening that frayed ends produce. A cheap soldering iron from the hardware store handles this for years of cord replacements.
Crossbow Owners Who Should Have This on the Shelf
Active crossbow hunters who pull their bow regularly through the year are the core audience. Pro shop technicians and archery range staff use the 20 ft size because it covers many repair jobs at a low per-rebuild cost. DIY builders putting together their own cocking aids should keep a length on hand as raw material. Families with multiple crossbows in the household get the most out of the bulk length because one purchase serves several bows. Anyone running a crank cocking system in particular should have a spare length because crank cord wears faster than rope cocker cord.
