RIGEL carbon chainrings combine aerodynamic design with advanced engineering to deliver maximum efficiency and lightness with every pedal stroke.
Their forged carbon body reduces weight without compromising stiffness, while the 7075-T6 anti-wear aluminium core protects the chainring contact area, preventing carbon friction and premature wear. Developed for riders seeking pure performance on gravel and road bikes, RIGEL chainrings are compatible with SRAM, Race Face, Easton, and Hollowgram drivetrains. Carbon fibre is continuously molded around each tooth, achieving unique precision and strength, as well as a striking and unmatched aesthetic that will leave no one indifferent. There's nothing like it.

Anti-wear technology
Gemini crafted the core of each tooth from 7075-T6 aluminium alloy, the hardest aluminium, to transmit power while providing high wear resistance, while carbon fibre covers the core laterally, reducing dynamic friction and noise with each link in the chain, creating an ultra-light and aerodynamic chainring structure.
You will feel an unparalleled smoothness when pedalling.
Maximum lightness, rigidity and minimum friction with a design
Rigel is designed to improve the performance of a conventional chainring in every way, including weight, aerodynamics, and power transfer. Honestly, what's most striking is how spectacular your bike looks when you ride it.
There's simply nothing like it.
HyperCars technology for your bike
More than three years of research and development, over 500 prototypes, thousands of kilometres of testing in all kinds of conditions by the most demanding riders... the result? Two international patent applications and the most technologically advanced chainring.
Continuous Fiber Teeth
Thanks to a process involving over 100 tons of controlled pressure and the specific arrangement of the material in the mold, the composite fibres are arranged in the geometry of each tooth around the metal core with a structural concentric organisation that gives it a strength impossible to achieve with any other carbon fibre manufacturing process, such as those manufactured in layers or subsequent CNC machining.

Designed and manufactured by Gemini in Barcelona
Innovation is in Gemini's DNA. Having complete control over every process allows them to create pieces never before seen. That's why they design and manufacture under one roof, where Gemini engineers and craftspeople can ensure the excellence of each piece.
