Gemini Rigel Gravel/Roadbike

Gemini Rigel Gravel/Roadbike 

GEMINI presents the lightest direct-mount chainring on the market. Once again, the magic word is: carbon. More specifically: forged carbon.
Since their earliest youth, the developers at Gemini have been surrounded by bicycles and are now applying their acquired knowledge of composite materials manufacturing with the utmost precision. It took more than three years of development and research to bring this technologically advanced chainring to market. What makes the new Rigel Carbon chainring special lies within: a metal core made of 7075-T6 aluminum alloy, which provides the structural foundation of the chainring. The composite fibers are strategically aligned around each tooth, resulting in a level of strength that has never before been achieved with any other carbon fiber manufacturing process.
The benefits include efficient power transfer and high wear resistance. At the same time, friction and noise are minimized—all while maintaining a phenomenally low weight—and it’s all handmade in Barcelona.

Narrow-wide tooth profile
To keep the chain securely in place even without a chain guide, the teeth feature a special profile consisting of alternating narrow and wide teeth.

SRAM 8-Hole Direct Mount
The chainring is mounted directly to the crank arm, replacing any previous spider. The result is a clean, clutter-free look that saves weight while offering excellent stiffness.
