Our old friend Aaron Panone's now legendary 144# chainring is true work of art and passion for flawless technical design with a unique tooth profile designed for maximum engagement and minimal wear, manufactured to the highest quality standards.

Fully CNC machined in California from certified 7075-T6 aluminum plate stock and all edges (front and rear) are machine broken with a 45-degree 0.010-in deep chamfer for extremely smooth operation.

The new 15-panel model features the same signature ratio of three pockets engraved with speed lines on both sides, and has a solid design to pair more seamlessly with disc style cranksets (like Rotor), but also looks great on your classic Sugino 75s, Dura Ace 7600s, etc. 

Each chainring is packaged in a custom embossed & letterpress printed envelope.
