A trail, XC / marathon wheelset with textile spokes?
So far, there have been many approaches by well-known manufacturers, but all of them have brought unsatisfactory results. The young and extremely innovative think tank PI ROPE from Chemnitz in Saxony has made the impossible possible in cooperation with the Chemnitz University of Technology. The result is a textile spoke made of braided Vectran synthetic fibers.
The material is extremely robust, aging and weather resistant and has better mechanical properties than its steel counterpart. The tensile strength and damping are many times higher, but the weight of the fibers is five times lower. This provides the ideal prerequisite for a very light yet durable impeller, as the rotating masses in the important outer areas are minimized and the flexibility of the Vectran textile spokes prevents permanent, plastic deformation at high load peaks.
In collaboration with the well-known wheel and component manufacturer NEWMEN, hubs and rims have been specially developed that can accommodate the special ends of the PI ROPE spokes. The inspiration for this was, among other things, the tried and tested Evolution SL XA25 aluminum rim, which with its low weight and high stability offers an optimal basis.
The combination of PI ROPE textile spokes and NEWMEN hubs and rims results in a super light, yet stable wheelset that is not only suitable for trail bikes, but also especially for XC / marathon riders who want to take advantage of wide rims and low weight.
