Pi rope

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, pi rope, by thinking out of the box there could be other materials that feature enhanced performance, pi rope, as pi rope the case of ceramics for reduced-friction bearings. With this, he intended to provide a new product neetu kapoor on technological benefits that would lead to improved functionality, from weight to riding feeling, for cycling wheels.

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. Essentially the Vectran spokes can withstand up to kN vs.

After riding on various surfaces tarmac, dirt, loose gravel we were surprised by how stiff they were, which was noticeable when doing a small acceleration transmitting all the force with only a small effort. The only thing I can say is that we know a lot what someone has to do for developing fibre spokes. However, at the same time, the transversal elasticity helps dampen the vibrations transmitted from the ground and provides a smoother riding style. Always thought modulus of elasticity was an under-discussed topic with regards to cycling, especially in frames. Notify of. Now for a spoke, strength is needed due to cycles fatigue , but again stiffness will come from young modulus and this is the key. Support us!
