aarn x Retrogression 144# chainring - Born of Fire
"Dreams possess nightmarish figures
Burning, can't escape the embers
Lost are those who trust the liar
Satan's son, I'm born of fire!" - Slayer
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-colored "infernal" 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.
