I have used dyneema in sailing applications for sail control lines, and they are even starting to use dyneema for the standing rigging to hold up the mast. As such I know for a fact that the stretch and tension loosening you are experiencing is from the weave settling in and not fiber stretch. The fiber itself has less stretch than steel! It is nothing like the nylon guitar strings that someone had mentioned. This stuff just doesn't stretch. For sailboat lines you can get parallel fibers, with no weave, and there is almost NO stretch. You can also get pre "stretched" woven lines, where they put the lines under extreme tension to nestle the weave eliminating any stretch when used. Perhaps the spoke manufacturer could pre-stretch (pre-load) these spokes to eliminate the settling of the fiber. Good video.
How much is the hoop? Im up to $1,500 in my head, but havent gotten to the hoop yet. I know im a little high, but these prices are already rediculous. I can just buy some enve carbon and it comes with lifetime incident protection. Saving money in the process...
Na. Park tool is just a youtuber now. Before long there will be a better help ad or something. Because learning to fix/ build the bike isnt enough. We need to showcase spokes that cost $500 to put on your bike... I hate bird spokes @ $8 per spoke.
Regarding the weave vs fibers stretching causing the drop in tension, I can't help but think about nylon guitar strings. They are notorious for going out of tune when new; you need to keep raising the tension several times (typically over a few days) until the guitar stays in tune. Nylon and polyethylene aren't the same, but I still wonder if they aren't similar enough for the same issue to apply here.
Nylon is very stretchy, around 30% elongation at failure. Dyneema is very inelastic, at around 3% elongation at failure. Very much not the same, as you said.
@@Frostbiker Can confirm. I have no experience of Berd spokes but I do paraglide and they all use sheathed Dyneema lines. The sheathing can contract when wet so every now and then a glider can get out of trim because the lines have shortened but the Dyneema core doesn't stretch elastically. Another important thing to know about Dyneema is its very bad at handling sheer stress so *never* knot it as it will snap very easily. This used to be common practice when re-trimming paragliders during development/testing until some serious accidents happened (some fatal) and the practice was abandoned.
Dyneema is not nylon, dyneema does not stretch. If it's weaved, it may stretch a tiny bit initially, but it shouldn't be an issue. Metal does stretch. As does nylon, polyester, lycra, cotton, etc. Making the compliance claims questionable marketing to me. I tie all my dyneema in knots. But the only life on the line is the fish. Also, knotting dyneema is tricky as F. I normally use a uni-knot. The stuff is so slippery you have to get tricky even spooling it on the reel. An arbor knot will not suffice. I've had one give, leaving my whole spool unspooling itself with a fish on until it magically cinches tight. It makes fight fish weird. I now use flourocarbon on the spool with an arbor knot into a double uni-knot. I also use a flourocarbon leader that I change out seasonally, about 30 feet long. Mostly for lure fishing, so the line doesn't spook the fish. I tie a swivel to a lighter leader if baitfishing. I always do 1 long and 1 short leader (dual pole license) a 2.5ft and 5ft leader from weight to bait. Whichever tends to hit, I swap the other pole to match. Fish feed on the bottom, but you need to be out of the weeds. If bait fishing I tend to use powerboat mouse tails on a single egg hook. It makes removing the hook much easier. Now I mostly fly fish with barbless hooks. I even tie some of my own flies! I liken flyfishing to golf, it takes skill and drives you to be better. The main difference is flyfishing requires full attention all the time, where golf only requires it while up to bat. Bait fishing is like camping in call of duty, minus having to watch your back.
@@brandonhoffman4712 That makes sense. Paraglider lines aren't woven, they are straight fibres, often sheathed with other materials, so there's no stretch. The upper cascade, which is least likely to snag on rocks during take-off as it sits on top of the canopy, is often a single fibre of unsheathed dyneema, lower cascades have multiple fibres inside the sheathing. Any stretch due to woven fibres compacting would be very bad in a paraglider as line-length is critical to keeping the canopy correctly trimmed. Edit: I just googled and apparently "Ropes made from HMPE or LCP type material (for example Dyneema or Vectran) should be assumed to retain only 40 percent of their strength when knotted,".
Its mainly the weight but don't forget this is rotating weight that has a much bigger effect on the ride of a bike than weight elsewhere (e.g in the frame). Its also very hard to lose weight from wheels without compromising strength but these spokes don't have that problem.
Combating stretch of Dyneema is the hardest part with using it on standing rigging on sailboats. It's definitely the weaving of the fiber that compresses and elongates the rope. I guess that's one benefit to Zylon on Spinergy wheels, since it uses more parallel run fibers there's less initial modulus during tensioning. Maybe one day Spinergy will eventually become an aftermarket competitor for custom wheel builds...
The interesting part about these spokes is the fact they can be built at home or in a shop. The industry has seen many proprietary spoke/ wheel designs but lacked servicability or access to service. The benefit here seems to be the ability to select prefered hubs, rims and nips. Spinergy, Topolino and K-one are some great designs but lack the modularity of a design like Berds. We'll see how it plays out in the long run.
I'm not certain these spokes are woven. It appears to me to be similar to paracord. With straight strands of fibers inside a woven sheath. Someone from the paragliding community chimed in saying that's what they use and it has 0 stretch. The person did say the sheath can tighten up when wet though causing extra tension. As far as what's actually in there, I have no clue. I do agree with you on the braided dyneema. It does have some stretch, buy it's also minimal and once set taught it should require minimal adjustment. Zylon is stiffer than dyneema and more heat resistant. Googles "ai overview" states there are bicycle spokes are made from zylon. I wonder who? It would make a much better spoke, offering much better shear strength and impact resistance. I looked into it and couldn't find a brand.
@@brandonhoffman4712 Berd's are woven, that's how they get their hook shape at the end by splicing it in. Spinergy makes Zylon spokes, but they are sheathed in an outer jacket because Zylon is more susceptible to the elements than Dyneema. I'm not entirely sure what One-K uses...it might be tradename Twaron; One-K weaves it into several spokes and then encapsulate the whole thing in a resin to protect the fibers.
@@parktool Berd definitely has the market cornered on fiber spokes that can be laced to almost any wheelset, albeit some hub manufacturers may not exactly like the way they want you to enlarge certain eyelets or chamfer the edges.
I’m interested in learning how they ride, I’ve heard good things (they’re super light, strong, and have a little plushness) but the price definitely makes it something of an investment.
oh, theyre made of UHMWPE? I've seen this material used in keyboard switches! really interesting when materials science and technology spread across multiple hobbies
@kroubian I think that's a rim thing, not a spoke thing. Some rims require you to tighten the spokes from where the tire seats. I know some envy wheels do this. It's more common with aero wheels as they are trying to be aero. One word of warning with a rim like that. I learned in this chat that dyneema has poor shear strength. So having the dyneema coming out of a carbon hole might be less than ideal from a saftey/longevity sake. I'm also fairly certain if this were the cause of a failure, your warranty would probably be voided by the experimental floss spokes. Unless it were a no questions asked kind of thing.
It really does not matter but in this video we put the leading spokes inside of the trailing spokes. The theory here is that the leading spokes that see most tension and abuse under braking should have a direct brace against the hub.
fyi, Dyneme rope is what pro sailors use in the expensive full size Sydney to Hobart yacht races, these take 80/150 KGs of force easy (as sheets for the sails), so should work for wheels.
Leading and trailing spokes not where we wanted them was the major mistake. This was happening in multiple ways because the spokes do not have as many limitations as standard J bend spokes.
So go for a 32 spoke rim! Ouch indeed, $256 spokes. I feel like park tool crossed a line with this video. From how-to focused tool company vids, to the realm of youtubers showcasing things far outside the normal pay range.
We felt that this was an interesting process that some viewers would be curious about. We did not talk about why someone should or should not buy them, just about the process.

I’ve been running a Berd mtb wheelset for about a year. Honestly, I wouldn’t recommend them. They are far more compliant than traditional spokes, and while this does have some modest benefits, it is more of a negative if you generate a lot of lateral force on your wheels. My biggest issue is that the spokes keep failing on my rear wheel. The mode of failure probably isn’t what you think, in my case the threaded steel shanks of random spokes keep shearing. Granted, I’m a 230lb rider that enjoys dirt jumps, but I’ve never had so many spoke failures in such a short time. I probably wouldn’t lace another wheelset with Berds. They’re cool in concept, but their durability isn’t working out for me. They’re also quite a chore to tension, and they require more maintenance until the spokes stretch out.
@@parktool At the end of the threads. The threaded portion is left stuck in the nipple. Most of the time the broken spoke will wrap behind the cassette and hinder its ability to freewheel.
@@sebastianreddan1647 no, the wheels were built correctly, and the correct length spokes were chosen for the job. The threads were fully engaged in the nipples and at most a couple of the shanks extended past the end of the nipples by at most a millimeter.

@@dkumagai30 Thanks for the response, I am considering building up a set of these in 27.5 for my Pivot M6. Your experience above has me questioning if I should or not?
one other suggestion, if you used a torque tool, screwdriver like, then no matter what you cant over tension the rope, as this tool will stop you, also if you have a process down pat, then this can be in-built into this wrench, aka a number 1/2/3 so there is no mistakes, even for novice wheel builders.
Dyneema doesn’t absorb water so getting wet shouldn’t affect them. That is one of the reasons it is used ship mooring, sails, backpack cloth, vehicle recovery rope, etc.

If that's the case, I would think these are the perfect match for you. The material used is the same stuff used in some forms of body/vehicle armor. It's way stronger than a steel spoke. My brother is 250 lbs. and has a set of mountain bike wheels with these spokes. Had them for two years now and they have not even needed a tru.
@@sjc115 Yeah I was actually looking into building a cargo bike 36-hole wheelset with Berd setup. I just can't find the longevity for long rides, though I can carry a couple of spokes along no problem.
If you are using a screwdriver to tighten a spoke then could you put the screwdriver bit in a torque wrench. If you tighten each spoke to a certain torque then would save time adjusting spoke tension.

How do you tighten a loose spoke in the field without twisting the spoke?
With the spoke holder. There are some drawbacks like this.
What is the weight difference between the normal spoke To this?
You save about 2 grams over the most common light weight stainless spokes. About 120 grams per wheelset.
I have three sets of wheels that I had Berd build for me. They are very light and ride great. But I'm glad they built them--not me.
Is it possible to cut the spokes with the knife?
You sure can.
Asking for a friend or
Is it strong enough to withstand shocks?
Yes, these are very strong. These spokes were used on the bike that won this years olympic xc mountain bike race.
👍@@parktool
If these wheels give you more vertical compliance (comfort), how are they with rear wheel power transfer? I imagine there must be a small trade-off.
How much weight savings with the Berd?
On your wallet? Quite a bit ... ;-)
How does water affect the spokes? (Stretch and shrinkage when getting wet and drying out)
Dyneema doesn’t absorb water so getting wet shouldn’t affect them. That is one of the reasons it is used ship mooring, sails, backpack cloth, vehicle recovery rope, etc.
