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 finished with black & clear hand applied "acid contrast" anodizing and packaged in a custom embossed & letterpress printed envelope.
