PI ROPE wheelset 28 "R.38 Carbon Road Disc Center Lock
A light racing bike / gravel 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 provides the ideal prerequisite 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 prevents 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. In the current FADE hubs with pawl freewheel, as with their predecessor, durable bearings are pressed in stress-free and precisely, so that the often laborious adjustment of the axial bearing play is completely eliminated. Thanks to the slim shape in the middle part, the hub saves weight and is also more aerodynamic.
The built-in NEWMEN ADVANCED SL R.38 rims, like all NEWMEN ADVANCED SL components, are made of UD carbon fibers and impress with their first-class mechanical properties and low weight. The ideal basis for a light disc wheelset with low inertia.
The special rim profile offers more comfort and traction than ordinary high profile carbon rims. The slightly flared rim flanks also make this rim more resistant to external forces and give the tire a slightly rounder shape. This improves comfort and cornering grip, especially in the wet. Of course, the rims can be driven with sealing milk and tape tubeless.
