PI ROPE wheelset 28" Gravel FADE Center Lock Beast GR25 | Golden Shine
A robust Gravel wheelset with textile spokes, can that work? So far, there have been many approaches from well-known manufacturers, but all of them have produced unsatisfactory results. The young and extremely innovative think tank PI ROPE from Chemnitz, Saxony, has made the impossible possible in cooperation with the Technical University of Chemnitz. 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. These are optimal prerequisites for a very light, but nevertheless hard-wearing wheel, as the rotating masses are minimized in the important outer areas and the flexibility of the Vectran textile spokes prevents permanent plastic deformation at high peak loads.
Rims from Beast Components are the ideal basis for this extraordinary wheelset. The small manufactory from Dresden has dedicated itself entirely to the material carbon and manufactures with it at the highest level. This guarantees stability and durability.
With the GR25 you get a light but stiff rim. It shows its advantages especially on narrow trails. Steering commands are transmitted directly and smoothly, and the low weight has a positive effect when accelerating. Of course, fast passages on asphalt or gravel are also possible without any problems, so that one can speak of an all-round talent with this rim.
The hookless and extra reinforced rim flange ensures robustness. This also puts away harder punctures and thus prevents damage to this exposed area. In addition, the air pressure can be lowered, which significantly increases comfort and grip. In addition, the enormous inner width gives the tire perfect support, which prevents it from buckling in fast corners and creates more driving stability.
The rims are provided with an asymmetrical rim profile, which allows a more even angle of the spokes. This optimization allows the tension on both sides to be better balanced, which is beneficial to the durability of the spokes and the entire wheel.
The high-quality workmanship and the well thought-out choice of materials forgive you for a driving mistake and let the rims look like new even after many kilometers.
In cooperation with the well-known impeller and component manufacturer NEWMEN, hubs were specially developed that can accommodate the special ends of the PI ROPE spokes. In the current FADE hubs with pawl freewheel, as in the predecessor, long-lasting bearings are pressed in stress-free and precisely, so that the often tedious 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 makers of PI ROPE have confidence in their products and grant a 3-year guarantee on all material and manufacturing defects as well as a 2-year crash replacement.
