Description
PI ROPE wheelset 29" Light 6-hole Lucky Jack 6Ters SLS4 30 | Black Premium Edition
A cross country wheel set with textile spokes, a rim width of 30 mm and a weight of around 1000g, 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.
Thanks to the black PI PROTECT coating of the Vectran yarn before the braiding process, the properties of the textile spokes are improved. The treated surface not only looks good, it also offers better UV protection and reduces the impact of adverse weather conditions.
In addition, the abrasion resistance against external damage, such as that caused by stones and branches on the trail, increases. Mechanical loads that occur 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 could be qualitatively optimized again.
In cooperation with the well-known German component manufacturer NONPLUS COMPONENTS, hubs were specially developed that can accommodate the special ends of the PI ROPE spokes.
Extra large bearings support the black anodized hub body on a 17 mm axle . On the rear wheel, two more carry the freewheel body. Microgap end caps seal everything and keep dirt or water out of the inside of the hub. In addition, a unique ventilation system prevents the creation of negative pressure due to temperature fluctuations in the hub. As a result, no moisture is sucked into the ball bearings, which ensures a significantly longer service life and noticeably smooth running of the bearings.
The freewheel mechanism is technically exceptional. The conical gearing has a contact surface that is approx. 400% larger than conventional ones
Spur gear teeth and thus enables maximum power transmission with minimum wear. The very elaborately manufactured tooth back, together with the hard anodized surface, ensures low abrasion and thus also increases durability. The 45-fold toothing results in a maximum idle travel of 8°. This means that you always have optimal propulsion in every driving situation.
Duke has managed to improve the Lucky Jack compared to the SLS3 version. In doing so, they have once again pushed the apparently technically possible limits. A 30mm wide rim weighing just 310g is a direct challenge to the competition.
How did the French do this? They took a closer look at the individual elements of the rim and looked for optimization options. In particular, a new resin was used. This not only made it possible to slim down, but also to increase impact resistance at the same time. Similar to the SLS3 production process, post-processing or painting is not necessary here either.
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.
