Product Introduction

The Kappstein Remus Chainring is a precision-engineered fixed gear and singlespeed chainring, developed for riders requiring a 130 BCD interface with high stiffness and reliable drivetrain performance.

As a newer addition to the Kappstein chainring portfolio, the Remus was designed in collaboration with product designer Raphael Krome. Despite its lightweight, minimal structure, it delivers excellent rigidity and durability under demanding fixed gear riding conditions.

Manufactured from 7075-T6 aluminum and CNC-machined in Germany, the Remus provides a refined balance between structural efficiency, durability, and clean design.

Why This Chainring Is Different

• Designed specifically for 130 BCD cranksets, expanding compatibility
• Lightweight structure with high stiffness under load
• Optimized for fixed gear and singlespeed drivetrain reliability
• Clean, minimal design without compromising structural performance

Technology Inside

This chainring incorporates key Kappstein drivetrain technologies:

• Round-Teeth Technology – improves chain engagement and reduces sliding friction
• Precision CNC-machined geometry for stiffness and durability
• Optimized tooth profile for stable chain retention in fixed gear use

Real-World Performance

In fixed gear and urban riding, drivetrain simplicity requires components that deliver consistent performance under varying loads and conditions. The Remus chainring is engineered to provide:

• Smooth and consistent power transmission
• Reduced drivetrain friction and wear
• High stiffness despite lightweight structural design
• Reliable chain engagement in everyday and high-load riding
• Increased efficiency is subtly felt by the rider through a precisely tuned drivetrain

These characteristics make the Remus chainring particularly suited for fixed gear riders, urban cyclists, and courier use, where durability and consistency are essential.
