- Kappstein Sprocket ProLine: Precision Power for Champions
 
The Kappstein Sprocket ProLine is the pinnacle of performance for track cycling and Fixed Gear riders, engineered for 11-speed chains and trusted by Olympic champions. Debuted at the 2016 Rio Olympics by gold medalist Kristina Vogel, this sprocket is part of Kappstein’s renowned ProLine series, developed with Germany’s FES (Institute for Research and Development of Sports Equipment). Its narrower, lightweight design—just 49g at 16T—enhances power transmission and durability, making it one of the most advanced and wear-resistant sprockets on the market.
 
Crafted from premium 630 stainless steel and fully CNC-machined in our Gotha, Germany facility, the Sprocket ProLine features edged holes (15T–19T) for reduced weight and a striking aesthetic. Kappstein’s signature Round-Teeth-Design ensures smooth chain engagement, optimal fit, and extended durability, while elegant laser engraving with the Kappstein logo adds a touch of sophistication. Proudly 100% made in Germany, this sprocket delivers the precision and style demanded by professional athletes and urban riders alike.
