PI ROPE wheelset 29 " RL Squirrel X.22 Carbon
An XC wheelset with textile spokes?
So far, there have been many approaches from well-known manufacturers, but all brought little satisfactory 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, resistant to aging and weathering and has better mechanical properties than its counterpart made of steel. The tensile strength and damping is many times higher, but the weight of the fibers is five times lower. This provides the optimum conditions 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 avoids permanent, plastic deformation at high load peaks.
In cooperation with the well-known wheel and component manufacturer NEWMEN, hubs and rims have been specially developed to accommodate the special ends of the PI ROPE spokes. One of the reasons for this was the extremely lightweight Advanced SL X.22 carbon rim, which with its low weight and high stability provides the ideal basis for lightweight construction.
The combination of PI ROPE textile spokes and NEWMEN hubs and rims makes for a fast, light yet comfortable wheelset that is not only suitable for XC bikers but also for marathon riders.
