PI ROPE wheelset 29 "RL SUB1.1 Carbon Gen2
An ultralight 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 have been specially developed to accommodate the special ends of the PI ROPE spokes. In the revised second generation of hubs long-lived bearings are now stress-free and precisely pressed, so that the often laborious setting of the axial bearing clearance completely eliminated. This evolution has added a high level of usability.
In order to break through the magical 1050 gram of sound barrier, however, only one rim is considered for the PI ROPE RL SUB1 - "THErim" the ultra-light rim of the Würzburg carbon forge BIKE AHEAD COMPOSITES. True to the motto: "Borders are there to be exceeded!" sets the rim with less than 270g weight a benchmark in terms of lightweight construction. However, 24 mm mouth width also make it clear that this is a functional lightweight construction and not an exaggerated minimalism. The THErim-SL24 rims have been specially adapted to the requirements of PI ROPE textile spokes and crown this lightweight icon made in Germay.
The combination of PI ROPE textile spokes, NEWMEN hubs and BIKE AHEAD rims results in a fast, ultra-light yet comfortable wheelset that is not only suitable for XC bikers but also for marathoners.
