aarn 144# chainring

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.

Product is packaged in a custom letterpress printed envelope (53t doesn't fit in the envelope but it is included for all you collector-nerds).
