With the newly designed ?Ruphus? named chainring, Kappstein closes a gap and offers besides their proven sprocket also a solution for the crankset. CNC machined out of a 5mm 7075T6 aluminum plate the chainring is very stiff and light. It has 6 different CNC machined steps which leads to a very interesting and unique look with lots of details to explore. With only 99 grams (49T) and a great stiffness this chainring is a must have for every one values design and performance. Even for our friends on fixed gear bikes this chainring is a pretty good solution to optimize the drive train and to realize their full potential. The 8bar Team around Stefan Schott, the leader of the team, will ride the chainring in all the upcoming fixed gear events in 2016. This valuable experience of all these professional guys will be used in the continous development of our products.

?Pro Line? stands for a new product line, which has been specifically developed for the competitive sport and its extremely high demands. All products with the add-on ?Pro Line? have been optimized for a specific application. A variety of areas can be optimized which can include weight, stiffness, function, surface treatment or the material itself. The first product of this series will be a new sprocket, which was developed together with Institute for the Research and Development of Sports Equipment (FES). We designed a special sprocket which is compatible with the narrower 11-speed chain. This product has been developed for the German national track cycling team for the Olympic games in Rio 2016. The endurance athletes as well the sprinters will ride this product in training and of course in their respective competitions.
