The Sprocket ProLine combines all the advantages of the ProLine series and has been specially optimised for 11-speed chains. This sprocket was used for the first time at the 2016 Olympic Games in Rio by none other than Olympic champion Kristina Vogel. The narrower design makes it even lighter than the standard sprocket. It also ensures improved power transmission and is thereby particularly wear-resistant as a result. The high-quality laser engraving featuring the Kappstein logo completes the design.
