Berd PolyLight Spokes. Silly-light Polymer Spokes
Yes the world of not metal spokes has arrived again. It's the mid 90s all over again! Hopefully with less explode-y-ness than fiber flight spokes!
Berd PolyLight Spokes. Just got some in to rebuild a set of ENVE SES3.4s using these for a customer. We'll see how they go! Will post a few pictures in a little while as I get going on them. |

i want to hear what you think once they're built
have a set of hubs that need a rebuild |

Some photos. It's worth noting that the scale photos are on a crappy scale that doesn't have tenths of decimals. And I am unsure of its rounding protocol. So I suppose that could be 1.4g on the Berd, and 4.5g on the Sapim. Need to grab a better scale and check to get better numbers.
Sapim CX Ray from front wheel Berd Spoke for front wheel Nipple end, has threaded metal section inside the polymer end Hub end is a loop that gets pulled through the spoke hole on the hub Flexible This comes with; blue loctite, which their instructions recommend, as well as tiny wire to use to pull the loop through the hub, small rod-like sections of the material, and some leather to use in conjunction with a tool to prevent wind-up even my fancy Roval wind-up prevention tool won't work, because it could damage the polymers) . From their instructions: 5. Lace the wheel using the desired lacing pattern. Make sure to only engage the first few threads of each nipple to allow all spokes threads to reach the nipples. 6. Prior to beginning tensioning, apply blue Loctite to the threads of all the spokes. This will ensure the nipples do not loosen during use. Wipe off excess Loctite after the nipples are tightened. This smaller rod-like section of the material gets inserted into the loop and is what holds the spoke head end into the hub; works on J bend or straight pull.

This post gives me anxiety.

I inquired a while back and they said they weren't selling spokes, only building in house. How did you get them?

I inquired a couple weeks ago and they sold me spokes. I dealt with Brad. I have no idea how many people work there, but I'd bet you'll talk to Brad. |

Me too...fortunately the owner of these wheels is a very small lady, so I am less afraid than if was going to ride them! |

What could go wrong? Rhetorical question..

They sound cool to me, please do update once you've built up the wheels.

Berd PolyLight Spokes. Silly-light Polymer Spokes
I have laced one wheel (the front). It is now 615g, compared to 675 before I disassembled it. So, 60g for the mathematically challenged, which suggests 3g a spoke here, which lends credence to my thought on my scale's rounding abilities. Here are some photos.
The first picture shows using small (garrote gauge?) wire to pull the loop of the end of the spoke through the hub. It took a surprising amount of force to pull them through - my hands and arms are tired after having done it. It required looping the wire around a hand (gloved) and pulling quite hard. Then a rod is slipped through the loop on the end of the spoke, and then the spoke is pulled to capture the rod as such. Lacing is tricky, perhaps the second will be easier (I suspect it will) as it requires threading only the smallest amount of threads of the nipple possible onto the spoke, as these spokes have a huge amount of stretch at the onset. I was barely able to get the last one threaded on. I will now tension and true a little bit, but not much as I haven't made the required padded pliers to hold onto the spoke to prevent twisting. A trip to the store tomorrow to grab a set of somewhat expendable pliers is in order. Last edited by MaraudingWalrus; 01-16-2018 at 10:10 PM. |

Pretty neat, but the little cross rods aren't very cosmetically attractive. Is there a reason you couldn't put them on the inside of the hub flange? And yes, I think lacing a wheel with fancy shoelaces to save 60 grams is *perfectly fine*... Last edited by dgauthier; 01-17-2018 at 06:51 AM. |

Eh, no particular reason beyond that generally radially laced wheels are heads out; these spokes are considerably thicker than a regular spoke, so I also didn't want to run into any clearance issues either, this way is a smidge slimmer than heads in. |
