Premium Chainrings
Introduction
Kappstein develops chainrings for specific drivetrain requirements rather than applying one tooth design across every application.
The range covers professional track cycling, fixed gear, gravel, MTB and the Doppio gearbox, with each product matched to its intended chain interface, mounting standard and drivetrain function.

Professional Track Architecture
Elite ProLine and Elite Classic share the same low-drag, high-stiffness Elite architecture and are developed to the same professional engineering level. The difference is the chain interface: Elite ProLine uses the 1/2" × 11/128" ProLine system, while Elite Classic retains the traditional 1/2" × 1/8" track-chain format.
Core Technologies
Round-Teeth Technology. Controls chain-tooth contact geometry to reduce unnecessary sliding and support efficient, durable power transmission.
Teeth-Side Technology. Used on Ridge and Roque to guide chain entry and improve retention under lateral misalignment and rough-terrain conditions.
Product Positioning
Elite ProLine — Premium professional track chainring for the narrow ProLine system.
Elite Classic — The same professional Elite platform for riders preferring the traditional 1/8" track-chain interface.
Ruphus ProLine — High-performance track / fixed gear chainring with a more open structural design.
Ruphus Standard / Remus — Round-Teeth fixed gear and singlespeed platforms for 144 BCD and 130 BCD systems.
Ridge / Roque — Dedicated 1×11 Gravel and MTB chainrings using Teeth-Side + Round-Teeth geometry.
Doppio 32T — Dedicated chainring for the Doppio gearbox system.
Compatibility Note
Ridge and Roque are currently validated for 1×11 drivetrains using conventional 1/2" × 11/128" chain geometry. General 12-speed compatibility is not claimed; dedicated road-racing 1×12 products should be presented separately when released.
