aarn x Retrogression 144# 15 panel chainring - Pink Formingya

Our dear 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.

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

This wicked cool collaboration features unique pink gradient & charcoal grey drizzle 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.

⚠️ aarn chainrings are not returnable.
