PI ROPE wheelset 29 "RL Lucky Jack Ultra Carbon FADE | Black Premium Edition
An ultra-light XC wheelset with black 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.
Thanks to the new, black PI PROTECT coating of the Vectran yarn before the braiding process, an improvement in the properties of the textile spokes is achieved. The treated surface not only looks good, it also offers better UV protection and reduces the influence of negative weather conditions.
In addition, the abrasion resistance to external damage, such as those caused by stones and branches on the trail, is increased. Occurring mechanical loads are better absorbed and ensure greater durability. The resulting increase in rigidity is particularly noticeable when cornering. Another plus, the processing of the textile spoke has been qualitatively optimized again.
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 new FADE Straightpull hub generation, the long-life bearings are pressed in precisely and without tension, 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.
With the help of the DUKE Lucky Jack Ultra SLS2 rims, the weight of the wheelset remains well below 1100 grams. With an outer width of 30 mm and an inner width of 24.5 mm, the rims not only offer excellent lateral stiffness, but also give the tires an optimal support width. Even with low air pressure, the driver does not have a spongy driving experience, as the tires are more difficult to bend to the side. The grip and comfort of the tires increase remarkably! Of course, the rims can be driven with sealing milk and tape tubeless.
For increased wheel rigidity, the rims come with an asymmetrical profile, which enables a more even angle of the spokes. This optimization of the spoke angle has a number of advantages. The spoke tension on both sides can be better adjusted to one another, which is beneficial to the durability of the spokes and the entire wheel. Thanks to the optimized SLS2 manufacturing process, the weight of the rims is only 285 grams in the PI ROPE version.
