 | Our RIGEL carbon chainrings are a masterpiece of engineering that takes drivetrains to the next level. They combine 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 minimizes friction, while the wear-resistant 7075-T6 aluminum core protects the chain contact area, providing greater tooth durability .Each Rigel snare drum is handcrafted in our Barcelona workshop , using our proprietary technology and the finest carbon fiber. We continuously mold the fiber onto the metal teeth, achieving a fiber distribution impossible to obtain with any other process. The |  |
