RIGEL

Swipe and uncover the most technologically advanced carbon chainring

Maximum lightness, stiffness, and minimal friction with an unprecedented design

In an era where races are decided by fractions of a second, the enhancements that enable you to go faster make the difference between reaching the top of the podium or not. Rigel has been developed in carbon, enhancing the efficiency of conventional chainrings, minimizing friction with the chain to help you be the fastest, with a singular chainring .

From only 39gr.*

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.

Patent pending Anti-Wear technology

The metal core of each tooth, crafted from 7075 T6 Aluminum alloy, efficiently transfers power to the chain, providing high wear resistance. Simultaneously, the carbon fiber covering minimizes dynamic friction and noise with every link, creating an ultralight and aerodynamic chainring structure.

Continous Fiber Teeth

Thanks to a process involving controlled pressure exceeding 100 tons and the specific arrangement of materials, the composite fibers are strategically oriented in the geometry of each tooth around the metal core. This structural organization provides a level of strength impossible to achieve with any other carbon fiber manufacturing process, such as layering 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 extend the life of your RIGEL carbon chainring for many more kilometers. An overly stretched chain can structurally impact the teeth. This way, you will extend the life of your RIGEL carbon chainring for many more kilometers.

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. 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.
