Product Introduction
The Kappstein ProLine Sprocket is a high-precision track and fixed gear sprocket, developed to work in combination with Kappstein ProLine chainrings for maximum drivetrain efficiency and durability.
Manufactured in Germany from high-grade stainless steel and CNC-machined for precision, the ProLine sprocket is designed to withstand extreme loads while maintaining consistent engagement behaviour. It is widely used in professional track cycling (for example, German National Team), where drivetrain reliability and efficiency are critical.
As part of the ProLine system, this sprocket is engineered not as a standalone component, but as part of a coordinated drivetrain interface.
Why This Sprocket Is Different
• Designed as part of the Kappstein ProLine drivetrain system
• High-strength stainless steel construction for extended service life
• Optimized engagement geometry for smooth and efficient power transfer
• Engineered for professional track and fixed gear applications
Technology Inside
This sprocket incorporates key Kappstein drivetrain technologies:
• Round-Teeth Technology – reduces sliding friction and improves efficiency
• ProLine Engagement Geometry – optimized for precise chain interaction
• High-precision CNC machining for durability and consistency

Real-World Performance
In track cycling and fixed gear riding, drivetrain components are subjected to high torque loads and continuous stress. The ProLine sprocket is engineered to deliver:
• Smooth and efficient power transmission
• Reduced drivetrain friction and wear
• Highly durable performance under repeated high-load conditions
• Stable and consistent chain engagement
• Increased efficiency is subtly felt by the rider through a precisely tuned drivetrain
These characteristics make the ProLine sprocket particularly suited for competitive track cycling and high-performance fixed gear setups.
Applications
Ideal for:
• Track Cycling
• Fixed Gear Bikes
• Singlespeed Drivetrains
• Professional and competitive riding
System Compatibility (Important)
The ProLine sprocket is designed to be used with:
• Kappstein ProLine chainrings (Elite, Ruphus ProLine)
• 1/2" × 11/128" chains (Shimano · KMC · Connex)
For optimal performance, it should be used as part of the complete ProLine drivetrain system.
