Raw Beauty. Next Stop: Anodizing. ⛓️✨

​There’s something captivating about the raw, silver shine of freshly CNC’d aluminum. This is the Mad Max chainring in its purest form, showing off every precise cut and structural detail.

​It’s perfect, but it’s not finished. We’re sending this batch off for hard anodizing to add that signature protection and deep color you love.

​From raw metal to relentless performance. The transformation begins.

CHROME SOUL. ⛓️✨

​There is a unique coldness to stainless steel that no other material can replicate. We’ve captured that raw, mirror-polished spirit to define the new CHROME SOUL Stainless Cog.

​No coatings, no shortcuts. Just the unwavering essence of high-grade steel, refined with our signature CNC precision. It doesn’t seek the spotlight; it commands the street with a steady, silver composure.

​The next evolution of Alter. Coming Soon.
