PI ROPE wheelset 29 "RL One XA25 aluminum FADE
A trail, XC / marathon wheelset with textile spokes?
So far there have been many approaches from well-known manufacturers, but all of them have not produced satisfactory results. The young and extremely innovative think tank PI ROPE from Chemnitz, 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 steel counterpart. The tensile strength and damping is many times higher, but the weight of the fibers is five times lower. This offers optimal conditions for a very light but 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 were 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, as well as the new FADE straightpull hub generation. In this case, the long-life bearings are pressed in precisely and without tension at the factory, so that the often laborious adjustment of the axial bearing play is completely eliminated. A high degree of user-friendliness was gained through this further development. The construction of the freewheel is completely different from the previous model. The goal was a low noise level. The result was the FADE pawl system. 3 pawls engage in a new type of tooth profile. To increase durability, the diameter was increased and the individual pawls were made short and wide. This means that the forces generated are distributed over a larger area.
The combination of PI ROPE textile spokes as well as NEWMEN hubs and rims results in a super light yet stable wheelset that is not only suitable for trail bikes but especially for XC / marathon riders who want to take advantage of wide rims and low weight.
