Gemini Rigel Direct Mount Carbon Road and Gravel Chainring

The GEMINI RIGEL Carbon Chainring is an elite structural masterpiece that merges the limits of advanced carbon fiber metallurgy with aggressive aerodynamics. Handcrafted in limited, exclusive production runs in GEMINI’s Barcelona workshop, the RIGEL's structural chassis is built using a proprietary continuously molded forged carbon process. Rather than using chopped fibers, continuous carbon filaments are layered and compressed into each individual tooth under extreme pressure, providing unprecedented structural integrity and lateral stiffness that resists deflection during maximum out-of-the-saddle efforts. To conquer the fast wear rate common to raw carbon teeth, GEMINI engineers have co-molded a premium 7075-T6 anti-wear aluminum core inside the chainring's contact profile, shielding the carbon from chain friction while preserving incredibly smooth, silent mechanical engagement.

Designed primarily for Gravel racers and Road pure-performance riders seeking to eliminate every redundant gram, RIGEL is available in 40T, 42T, 44T, and 46T profiles. Engineered with a 6.5mm Offset, it provides optimized, low-drag chain alignment on modern 1x11, 1x12, and 1x13 speed drivetrains. It features universal multi-interface compatibility, supporting SRAM 3-bolt, SRAM 8-bolt (the exact match for the iconic Cane Creek eeWings), RaceFace/Easton, and Cannondale Hollowgram direct-mount systems, presenting a breathtaking, high-contrast industrial look that matches the raw metal luster of titanium cranks.
