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.

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

This special collaboration features unique multi-purple anodized finishing and each chainring has slight variances from one to another, making no two exactly the same.

Packaged in a custom embossed & letterpress printed envelope boldly sporting our logo.

Oh, and if you’re buying one of these just to turn around and immediately hock it on eBay for a profit, that’s a perfect example of what’s known as a “dick move”.
