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.

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.

If a new wheel tech is released, say for example, TPU tubes, pi rope brand new tire, or a new rim standardfeel free to start the discussion in the popular "Road".

But now Pi Rope laces up tons more opportunities for customization. Pi Rope first debuted their superlight textile spoke wheels back in with their unique braided Vectran polyester fiber in its natural off-white. Then, just half a year later they got a stealthy black update, in the complete Squirrel Black edition wheels, developed with superlight Newmen carbon rims. Now that Pi Rope has dialed in the process that dyes the polyester fiber, they are dramatically expanding their color options…. Each Pi Rope wheel is built to order, so you can add a small color accent with one or two spokes, use all of one color of spokes, or go crazy with rainbows. They even offer customized anodized nipple colors as well.

On their own, these fibers have similar strengths to steel. 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. Proprietary hubs and rims seems like less choices. Always thought modulus of elasticity was an under-discussed topic with regards to cycling, especially in frames. Ride more - work less. HUNT has quickly gone from being the hunter to the…. 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. Tech Details 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. Apparent refusal to do side-by-side tests with regular wheels to prove their worth? Last edited by apr46 on Tue Feb 07, am, edited 1 time in total.

Yes the young modolus is the most necessary thing. Inline Feedbacks. 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. These were produced from the partnership with Newmen Components , developing suitable hubs and rims for the spokes, proving light and extremely reliable in various tests. 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. Besides, in case of breaking, they can be easily substituted by any experienced wheel builder. Reply to Shenandoah.
