RIGEL

The most advanced and stunning 1X carbon chainring for gravel/road

Anti-wear technology
Patent Pending

We’ve crafted the core of each tooth from 7075-T6 aluminum alloy, the hardest aluminum available, to transmit power while providing high wear resistance. The carbon fiber laterally encases the core, reducing dynamic friction and noise with each chain link, creating an ultra-light and aerodynamic chainring structure.

You’ll experience an unmatched smoothness while pedaling.

Maximum lightness, stiffness, and minimal friction with a single-word design:
SPECTACULAR

Rigel is designed to outperform a conventional chainring in every aspect, including weight, aerodynamics, and power transfer. But honestly, what grabs the most attention is how spectacular your bike looks when you install it. There’s simply nothing like it.

HyperCars technology for your bike

Rigel is made with the same carbon fiber used in supercars. The carbon fiber and its manufacturing process completely differ from what you’re used to. Over 100 tons of controlled pressure, combined with the specific material arrangement and our technological development, make Rigel a unique piece at the forefront of technology. This effort has led to the filing of 2 international patents and the creation of the most technologically advanced chainring.

Continous Fiber Teeth

During the manufacturing process, carbon fibers are arranged in the geometry of each tooth around the anti-wear metal core with a concentric alignment. This alignment provides structural strength in the teeth that is impossible to achieve with any other carbon fiber manufacturing process, such as layered or CNC-machined carbon.

FAQs

CAN I USE RIGEL WITH ANY TYPE/BRAND OF CHAIN?

The tooth design of Rigel has been developed to be compatible with any chain on the market for 11 12, and 13 speeds, including Shimano, SRAM Eagle, and SRAM Eagle Flattop chains.

DO I HAVE TO USE A NEW CHAIN WHEN INSTALLING A NEW RIGEL?

We recommend using a new chain when installing the chainring and regularly checking its wear. This will significantly extend the lifespan of your RIGEL carbon chainring. An overly stretched chain can structurally damage the teeth.

WHAT DURABILITY DOES A RIGEL CHAINRING HAVE?

Defining a general durability for a component like this is impossible, as its longevity depends on various factors such as the rider’s power output, terrain elevation, maintenance, and more. These factors can cause some cyclists to cover more kilometers than others, just as with a conventional aluminum chainring. Therefore, we can’t provide a specific figure. However, keep in mind that the core is made of metal, so the wear will be similar to that of an aluminum chainring.

HOW CAN I DETERMINE IF THE OFFSET IS SUITABLE FOR MY BIKE?

The 6.5 mm offset is compatible with all bikes that have a 142 mm rear hub configuration.

IS IT TRULY THE LIGHTEST CHAINRING IN THE WORLD?

Yes, it is the lightest Direct Mount aero chainring for gravel/road. You can reduce the weight by about 60 grams compared to a standard aluminum chainring, as it primarily uses carbon fiber for both the structure and the teeth, despite having an internal metal core that is used solely to extend its lifespan against wear.

WHAT MAINTENANCE DOES IT REQUIRE?

We recommend lubricating your drivetrain with a dry lubricant to prevent particles from sticking to the chain, which could cause premature wear on your RIGEL carbon chainring. Keeping your drivetrain clean and well-lubricated will extend the life of RIGEL, as well as changing the chain before it becomes too stretched.

WHAT MAKES RIGEL’S TECHNOLOGY SO SPECIAL?

Rigel is made from Forged Carbon, resulting in a continuous fiber structure within the tooth that is unattainable with traditional carbon fiber manufacturing processes. Additionally, its internal metal core enhances the performance of the carbon teeth against wear.
At Gemini, we are committed to creating unique and innovative products that disrupt the techniques used so far. This is our contribution to enhancing your cycling experience.
