Gemini Rigel Shimano Direct Mount Boost MTB Chainring

Gemini Rigel Shimano Direct Mount Boost MTB Chainring

The Gemini Rigel Shimano Direct Mount Boost MTB Chainring is a handcrafted carbon fiber chainring designed for performance. Weighing under 70 grams, it combines lightweight construction with exceptional durability. Built with Forged Carbon Technology, the Rigel chainring features a 7075-T6 aluminum core that increases stiffness and longevity. This aluminum reinforcement ensures the chainring wears and performs like a traditional alloy chainring while maintaining the weight savings of carbon fiber. Its solid aero design further enhances strength, rigidity, and aerodynamic efficiency on the trail.

Engineered for Boost (52 mm) chainlines, the Gemini Rigel chainring is compatible with Shimano and SRAM 11- and 12-speed chains as well as SRAM Flattop chains for 13-speed drivetrains. This makes it a versatile upgrade for mountain bikers seeking a high-performance, direct-mount chainring that delivers both power transfer and reliability.
