PI ROPE wheelset 29 "RL SUB1.1 Carbon Gen2
An ultra-light XC 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, special hubs were developed that can accommodate the special ends of the PI ROPE spokes. With the revised second generation of hubs, long-life bearings are now precisely and stress-free pressed in, 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.
In order to break the magical 1050 gram barrier, the PI ROPE RL SUB1 can only use one rim - "THErim", the ultra-light rim from the Würzburg carbon forge BIKE AHEAD COMPOSITES. True to the motto: "Limits are there to be exceeded!" With a weight of less than 270g, the rim sets a benchmark for lightweight construction. However, an internal width of 24 mm also indicates that this is functional lightweight construction and not excessive minimalism. The THErim-SL24 rims have been specially adapted to the requirements of the PI ROPE textile spokes and crown this lightweight icon made in Germany.
The combination of PI ROPE textile spokes, NEWMEN hubs and BIKE AHEAD rims results in a fast, ultra-light and yet comfortable wheelset that is not only suitable for XC bikers but also for marathon riders.
