PI ROPE wheelset 29" Light 6-hole Advanced SL A.30 Carbon | Golden Shine
A cross-country 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.
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.
Like all Newmen carbon rims, the built-in Nemwen Advanced SL A.30 rims are made of high-end UD fibers and impress with their first-class mechanical properties and low weight. They are the ideal basis for a stable all-mountain wheelset.
The hookless construction predestines them for tubeless use. The significantly reinforced rim flange withstands possible punctures better and allows driving with little air pressure. In order to avoid weak points, the spoke holes were drilled using a special method.
Due to the flanks that are slightly outwards, the shape of the tire is rounder, which means that a much better cornering grip and increased safety are achieved.
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.
