Gemini RIGEL Direct Mount Carbon Chainring — e*thirteen MTB

A forged carbon chainring around a 7075-T6 aluminium core — carbon's weight with a metal wear surface, for e*thirteen MTB cranks.

Continuous Fiber Teeth lay the carbon concentrically around an anti-wear core of 7075-T6, the hardest aluminium alloy in common use, in a patent-pending process. Quieter, lighter, and it keeps its teeth. Around 39 g in a 30T.
