A 12t lock ring works best with the Fibonacci Spacer Kit. These should be available through your LBS.
As of April 15, 2026 my anodizer is discontinuing Blue, Lime Green, Pink, and Turquoise. Once the parts in these colors are sold out, they will not be restocked and will be removed from this page. I’ll miss them and I know some of y’all will as well. Thank you for understanding.
Functional, durable and sexy!
