Gemini Rigel 8-Bolt Boost MTB Chainring
The Gemini Rigel 8-Bolt Boost MTB Chainring is one of the most stunning 1x chainrings available. The Rigel chainring is made using Forged Carbon Technology which makes it very light. In addition, it is reinforced with 7075-T6 aluminum for add strength and durability. In fact, the aluminum core allows it to still wear and perform like a standard aluminum chainring. Even more, the solid design of the Gemini Rigel MTB Chainring further increases strength and rigidity while also providing an aero advantage.
This Gemini MTB chainring is made for Boost (52 mm chainline) 8-bolt direct mount cranksets. It is compatible with 11- and 12-speed SRAM and Shimano chains as well as SRAM Flattop chains on SRAM 13-speed drivetrains.
