The world of cycling is dominated by three materials: steel, aluminum, and carbon fiber, which feature unique properties that make them excel in their specific applications. However, by thinking out of the box there could be other materials that feature enhanced performance, as was the case of ceramics for reduced-friction bearings. With this, he intended to provide a new product based on technological benefits that would lead to improved functionality, from weight to riding feeling, for cycling wheels. Not long after, thanks to the cooperation with Newmen Components and a dedicated process of constant self-improvement, they finally commercially launched their first products in Nowadays, the brand offers a selection of different spokes, hubs, and full wheelsets for different cycling disciplines including road, gravel, and MTB. These represent featherweight wheels with self-damping capacity and similar properties in terms of stiffness, braking load, resilience, aerodynamics, and wear to the commonly used steel. On their own, these fibers have similar strengths to steel.

German-made Pi Rope showed us yet another example of superlight XC wheels built up with textile fiber spokes, and gave us the lowdown of why they actually outperform traditional steel spokes. In fact, these polyester fiber spokes made by Pi Rope are actually already available. And Pi Rope can build them up into a XC wheelset as light as g. Quickly looking at the difference from these Pi Rope fiber spokes to those Berd ones found on the Tune wheels. They were a bit tight-lipped on exactly how the connection is made, but confirmed that it is a two-piece joint with one part inserted into the end of the hollow spoke, which then compresses into the nipple with its external male threads. In the end the spoke is held in the nipple both mechanically and with an adhesive. To make that work Pi Rope has a development partnership with German wheel maker Newmen who supplies quality rims and hubs designed to accommodate the unique thread in nipples. That is mostly to keep things simple as they establish their production capabilities relative to demand. To eliminate any twisting or wind-up of the spokes, the wheels are built by initially threading the flexible textile spoke into the hub shell. Then the wheel builder inserts the nipple into the rim, and holds it fixed in place while they tighten a nut onto the end of the nipple through the rim. The result is no spoke twist, but it also limits the ease of adjusting the wheel with a tire mounted.

Spinergy started with Vectran Spokes. Do not buy anything from the pi rope, the products are very fragile and the company does not give any guarantee, pi rope.

However, it is when you braid them that their properties in terms of tension and flexibility are improved, making them excellent candidates as spokes.

Since the designers did not want to compromise the properties and provide an excellent product, the spokes can only be matched with specific rims and hubs with large holes that do not suit commercial standards.

You feel the lack of lateral stiffness when descending at high speeds and I personally dont feel as comfortable pusing them as hard on the road. HUNT has quickly gone from being the hunter to the….

However, at the same time, the transversal elasticity helps dampen the vibrations transmitted from the ground and provides a smoother riding style. The next remark is the spokes look, as they are completely flexible like ropes when not under tension. Forum rules The spirit of this board is to compile and organize wheels and tires related discussions. They are braids of polymer fibers with high flexibility in the transversal direction but a high longitudinal tensile modulus. I like the berd system better.

Those same crazy lightweight mountain bike wheels we saw last summer with Pi Rope textile Vectran spokes just got a new stealthy all-black limited edition.

The only thing I can say is that we know a lot what someone has to do for developing fibre spokes. Always thought modulus of elasticity was an under-discussed topic with regards to cycling, especially in frames. So what I can say is to invite you for some tests. Its a direct equivalent to a spring rate. Over a kilo? If a new wheel tech is released, say for example, TPU tubes, a brand new tire, or a new rim standard , feel free to start the discussion in the popular "Road".

As they are finalizing production setup it may take a little while to get a set of wheels, but you should be able to order them by contacting Pi Rope directly, with expected summer into autumn delivery based on availability. Apparent refusal to do side-by-side tests with regular wheels to prove their worth?
