Classic Sprocket (1/8")

Kappstein Classic Sprocket (1/8")

The Kappstein Classic Sprocket is the essential counterpart to our Elite Classic chainring. Designed for the traditional 1/2" × 1/8" chain standard, in particular for Izumi and KMC track chains. This sprocket brings professional-grade CNC precision to the broader track cycling market.

For years, the Kappstein Proline series has defined what is possible in track cycling drivetrain efficiency. Now, we are bringing that world-class engineering to the traditional 1/8" market. Introducing the Kappstein Classic Sprocket.

Designed for professional athletes and ambitious track cyclists who prefer the robust feel and compatibility of a 1/8" track chain, the Classic Sprocket offers no compromises. It features the same CNC-machined precision and ultra-stiff architecture as our Proline series, but optimized for the traditional track width.

The sprocket is the final, crucial link in your power delivery. We engineer our Classic Sprockets with the same precise tolerances as our world-class chainrings to ensure a perfect system match. This precision ensures that every watt transmitted through the chain is converted into forward momentum with minimal friction and maximum stability

Why This Sprocket Is Different:

•    Precision Machining: Each Classic sprocket is CNC-turned for perfect concentricity.

•    Optimized Tooth Geometry: Specifically designed to provide a very smooth and ultra quiet ride

•    High-Strength Stainless Steel: Offers a significantly longer lifespan and better wear resistance than standard steel options.

•    Professional Reliability: Trusted by athletes who prefer the robust nature of the 1/8" system.

Technology Inside This sprocket incorporates Kappstein’s core engineering principles:

•    Round-Teeth Technology – creates a smoother entry and exit for the chain links, reducing vibration.

•    Enhanced Surface Finish – reduces friction between the chain rollers and the sprocket teeth.

•    Optimized Width – tailored for a perfect fit with 1/8" Izumi and KMC track chains.
