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, 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, pi rope. With this, he intended to provide a new product based on technological benefits that would lead to improved functionality, pi rope, from weight pi rope 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

Pi rope

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. With that in mind Pi Rope can lace and tension a textile spoked wheel with stiffness in mind, leaving plenty of extra spoke strength in reserve.

Privacy Terms. Stronger is a loosely defined pi rope, but the only context in which I can imagine it being true is if these spokes have greater elasticity, then they may be in a more stretched position when fully tensioned, pi rope, and therefore may resist a complete loss of tension better when under extreme load scenarios.

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 just a bit more than one kilogram Pi Rope Squirrel Black Edition XC wheels are available in limited numbers, and exclusively through German online retailer r 2 bike now…. He also mentioned at the time potentially coloring spokes black or other colors for some production runs, as it also helps protect the fibers from UV degradation, something that otherwise requires an additional white treatment to the raw fiber spokes. Their partnership with r2bike. The wheels feature the X.

That means less need for wheel truing, especially when built up with a carbon rim that can move more elastically as well. As for actual availability, Pi Rope is building the wheels now based on their patent application from Proprietary hubs and rims seems like less choices. Plus, like the Berd polyethylene spokes, their own tension keeps them from collecting much in the way of contamination. Learn how your comment data is processed.

Apparent refusal to do side-by-side tests with regular wheels to prove their worth? Do not buy anything from the pi rope, the products are very fragile and the company does not give any guarantee. For more road use though, I would stick to something with nice regular steel spokes. I always think this property, second to geometry and sans extremes, is what tends to make different materials feel the way they do rather than the more oft discussed ultimate strength and strength to weight. They want to charge for the guarantee, that is, there is no guarantee. Follow Us On. Good for them. I question whether they actually make for a stronger wheel because their ultimate tension strength is greater.
