Kappstein Ruphus ProLine Chainring: Precision Meets Style
The Kappstein Ruphus ProLine chainring is the ultimate upgrade for cyclists seeking elite performance and striking design. As the perfect counterpart to the Sprocket ProLine, this chainring is optimized for
1/2" x 11/128" chains, delivering seamless power transfer for track cycling, Fixed Gear, and singlespeed riders. Designed by Munich-based product designer and bike enthusiast Raphael Krome, the Ruphus ProLine blends cutting-edge engineering with a bold aesthetic, making it a favorite among competitive cyclists and urban riders alike.
Crafted from 7075-T6 aluminum and fully CNC-machined in our Gotha, Germany facility, the Ruphus ProLine combines lightweight construction with exceptional durability. Its hard-anodized coating provides a surface up to three times harder than standard aluminum chainrings, rivaling the toughness of Kappstein’s stainless steel sprockets. Paired with our exclusive Round-Teeth-Design, this chainring ensures superior chain retention, reduced wear, and smoother performance, even under the intense demands of professional racing.
