Gemini Rigel MTB Chainring SRAM 3 Bolt

Combining aerodynamic design with advanced engineering to deliver maximum efficiency and lightness with every pedal stroke. Their forged carbon body reduces weight without compromising stiffness and reduces friction, while the 7075-T6 anti-wear aluminium core protects the chain contact area, offering greater durability .

Each Rigel chainring is handcrafted in Gemini's Barcelona workshop, using their own technology and the finest carbon fibre. Gemini continuously mold the fibre onto the metal teeth, achieving a fibre distribution impossible with any other process. The result is a unique, exclusive, and limited-production piece. The development of this chainring has taken us over three years and earned us two international patents.

Honestly, when you receive it and mount it on your bike, and see how the light bounces off it, you'll realise there's nothing like it, and that it's a spectacular plate.

Maximum lightness, rigidity and minimum friction with a design never seen before

In an era where races are decided by tenths of a second, and upgrades that allow you to go faster are the difference between landing on the top step of the podium or not. Rigel has been developed in carbon, improving the efficiency of conventional chainrings, minimising friction with the chain to help you be the fastest, with a single chainring.

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.

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.

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 Gemini design and manufacture under one roof, where engineers and craftspeople can ensure the excellence of each piece.
