Kappstein track chainrings are developed for high-performance track cycling and fixed gear drivetrains, where efficiency, stiffness, and engagement precision are critical.
Manufactured in Germany using CNC-machined 7075-T6 aluminum, each chainring is engineered to deliver stable power transmission, low friction, and long service life under extreme riding conditions.
Engineering Focus
Unlike conventional chainrings developed through incremental refinement, Kappstein chainrings are designed using a geometry-driven engineering approach, focusing on:
• Chain engagement behaviour
• Load distribution across the tooth profile
• Reduction of sliding friction
• System-level drivetrain interaction
This results in drivetrain components that deliver measurable efficiency and consistent performance in real riding conditions.
Technology Overview
Kappstein track chainrings incorporate proprietary drivetrain technologies:
• Round-Teeth Technology – reduces sliding friction and improves efficiency
• ProLine Engagement Teething – optimized for 11-speed track drivetrains
• Precision CNC manufacturing for high stiffness and durability
