  • This chain ring is the pendant to the sprocket ProLine. So if you want to take advantage of an 11-speed chain, the Ruphus ProLine has the right gear for the crank set. Compared to the standard version of the Ruphus, the ProLine has an additional coating. Thanks to the hard anodizing, the surface of the chainring is up to three times harder than the conventional aluminium chainrings. The degree of hardness corresponds to that of a Kappstein stainless steel sprocket. The Ruphus Design The Ruphus design comes from the spring of Raphael Krome, a young Munich product designer and artist who has already been involved in projects for a well-known car manufacturer from Bavaria. He is also a member of the infamous Hardbrakers gang from Hamburg and thus a real bicycle enthusiast. This chain ring is also produced almost completely by Kappstein. Only the coating is taken over by specialized companies from the region. Kappstein ProLine - Fixed Gear Setups for 11-speed chain "ProLine" refers to a new product line, which was specially developed for performance sports or for extremely high requirements. All products that have been added with the "ProLine" add-on have been optimised. These optimizations include, among other things, weight, stiffness, durability, functionality, coating or the material. The weight reduction and improved performance are mainly due to the fact that all ProLine products are designed exclusively for the narrower 11-speed chains (1/2 inch x 9/128 inches). With special coating process and the unique gear technology "round tea design" (see next article) which is used throughout the ProLine series, we set new standards in professional equipment for cycling. The first product of the series was our Sprocket ProLine, which was created in preparation for the 2016 Olympic Games in Rio, in close collaboration with FES (Institute for Research and Development of Sports Equipment). In the same year, the "Elite" chain ring for the track and the design classic "Ruphus ProLine" for the drive front. As part of the further development of bicycle sports, more and more professional athletes are using the components of the Kappstein ProLine series. On the road and at different crits, the 8 bar team with Kappstein ProLine chain rings and sprockets is ready to start. Again and again the athletes emphasise the extreme smoothness and durability of the ProLine drive. At this point we would like to thank the team of FES, who is always with us with material and performance tests and their comprehensive know-how in performance sports. Together we are already developing new developments for the next Olympic Games 2020. What is behind the Kappstein "Round Teeth Design"?The Kappstein "Round Teeth Design" is the further development of the usual pointed teeth design. Compared to other toothed wreaths, the tooth contours of Kappstein chain rings and sprockets clearly show that the teeth are wider and less pointed together. The result is a more efficient power transmission with optimal fit of the chain. It also increases durability as the chain can be better tracked and guided by the teeth. The "round teeth" design is used with all chain rings and sprockets from Kappstein. NOTE: The Ruphus ProLine should only be combined with a Shimano, KMC or Connex 11-speed chain and a Kappstein Sprocket ProLine. No colour fastness can be guaranteed with this special coating process of hard anodising. Therefore, the colour varies between dark grey, grey gold and gold.
