Discover the most technologically advanced carbon chainring from 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. TheGemini Rigel MTB Chainring for SRAM 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—all 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.
Anti-Wear Technology (Patent Pending)
The metal core of each tooth, made from 7075 T6 aluminum alloy, transmits power to the chain while providing high wear resistance, while the carbon fiber coating reduces dynamic friction and noise at each 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 a level of strength impossible to achieve with any other carbon fiber manufacturing process, such as layered or CNC-machined carbon.
Features:
Compatible crank interface: SRAM 3-bolt
Standard offset: 3 mm
Number of teeth: 32T, 34T, and 36T
Drivetrains: 1×11, 1×12
CAN I USE RIGEL WITH ANY TYPE OR BRAND OF CHAIN?
Rigel’s tooth design has been developed to be compatible with any 11- and 12-speed chain on the market, including Shimano Eagle, SRAM Eagle, and SRAM Flattop chains.
DO I NEED TO INSTALL A NEW CHAIN WHEN MOUNTING A NEW RIGEL?
If you want to maximize the life of your Rigel chainring, we recommend using a new chain when installing it and monitoring the chain’s wear. This will extend the life of your Rigel carbon chainring for many more kilometers.
HOW LONG DOES A RIGEL CHAINRING LAST?
It’s impossible to define a general lifespan for a component of this type, 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 will 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 3 mm offset is compatible with all bikes that have a 148 mm Boost 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, which results 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.
