With the newly designed chainring named „Ruphus“, Kappstein closes a gap and offers besides their proven sprocket also a solution for the crankset. CNC machined out of a 5mm 7075T6 aluminum sheet 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.
