Discover the most technologically advanced 1X carbon chainring for Gravel and road cycling, brought to you by Gemini and Escapa.
In an era where races are decided by tenths of a second, the improvements that allow you to go faster are the difference between reaching the top of the podium or not. The Gemini Rigel Gravel / Road Chainring for SRAM Direct Mount 3-Bolt has been developed using carbon to improve upon the efficiency of conventional chainrings, minimizing friction with the chain to help you be the fastest with a single chainring.
HyperCars Technology for Your Bike
More than 3 years of research and development, over 500 prototypes, thousands of kilometers of testing in all kinds of conditions by the most demanding Riders… the result? Two international patent applications and the most technologically advanced chainring.
Patent-Pending Anti-Wear Technology
The core of each tooth is made of 7075-T6 aluminum alloy—the hardest aluminum—to transmit power while providing high wear resistance, while carbon fiber covers the core laterally, reducing dynamic friction and noise with each chain link, creating an ultralight and aerodynamic chainring structure. You’ll feel unmatched smoothness as you pedal.
Continuous Fiber Teeth
Thanks to a process involving over 100 metric tons of controlled pressure and the specific arrangement of the material, the composite fibers are arranged in the geometry of each tooth around the metal core with a structural organization that provides strength impossible to achieve with any other carbon fiber manufacturing process, such as layered or CNC-machined carbon.
Features:
Compatible crankset interface: SRAM Direct Mount 3-bolt
Standard offset: 6.5 mm
Number of teeth: 40T, 42T, 44T, and 46T
Drivetrains: 1×11, 1×12, 1×13-speed
CAN I USE RIGEL WITH ANY TYPE OR BRAND OF CHAIN?
Rigel’s tooth design has been developed to be compatible with any 11-, 12-, or 13-speed chain on the market, including Shimano, SRAM Eagle, and SRAM Eagle Flattop chains.
DO I NEED TO INSTALL A NEW CHAIN WHEN MOUNTING A NEW RIGEL?
We recommend that you use a new chain when installing the chainring and that you monitor the chain’s wear. This will extend the life of your RIGEL carbon chainring by many more kilometers; a chain that is too stretched can structurally damage the teeth.
HOW LONG DOES A RIGEL CHAINRING LAST?
It’s impossible to define a general lifespan for a component like this, since its durability depends on the force the rider applies while pedaling, the terrain, maintenance, and other factors. These factors can mean that some riders cover more kilometers than others—just as with a conventional aluminum chainring—so we can’t give you a specific figure. Keep in mind that the core is made of metal, so wear and tear will be similar to that of an aluminum chainring.
HOW CAN I TELL 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 REALLY THE LIGHTEST CHAINRING IN THE WORLD?
Yes, it’s the lightest Direct Mount chainring; the 30T version with SRAM 3-bolt mounting weighs around 39 gr., since it’s made primarily of carbon fiber for both the structure and the teeth, despite having an internal metal core that’s used solely to extend its lifespan.
WHAT MAINTENANCE DOES IT REQUIRE?
We recommend lubricating your drivetrain with a dry lubricant that prevents particles from sticking to the chain, which can lead to premature wear on your RIGEL carbon chainring. Keeping your drivetrain clean and well-lubricated will extend the lifespan of your RIGEL chainring.
WHAT MAKES RIGEL’S TECHNOLOGY SO SPECIAL?
RIGEL is made of Forged Carbon, resulting in a continuous fiber structure within the tooth that cannot be achieved with traditional carbon fiber manufacturing processes. Additionally, its internal metal core enhances the carbon teeth’s resistance to wear.
