Gain a decisive advantage on the road with the ROTOR Aero MAS 1x/2x Spider, a masterpiece of cycling engineering designed for cyclists who demand peak performance and uncompromising speed. This essential crank component is crafted for the serious road racer, triathlete, and time trial specialist looking to minimize drag and maximize every watt of power. Its solid, robust design not only ensures flawless power transfer but also significantly improves the aerodynamics of your entire crankset system.
The Aero MAS Spider is engineered to provide minimal air resistance, reduce drag and allow you to pedal faster with less effort. Its solid, disc-like design smooths airflow across your crankset, effectively turning your chainrings into an aerodynamic weapon against the wind. This meticulous attention to airflow dynamics translates into tangible gains, saving you precious watts and seconds when it matters most. Whether you´re in a breakaway, racing against the clock, or simply pushing your limits on a solo ride, this spider helps you slice through the air with superior efficiency.
Beyond pure aerodynamics, the ´MAS´ in its name stands for Micro Adjust Spider, offering a significant advantage in biomechanical optimization. This proprietary technology provides more intermediate positions for your oval Q RINGS®, allowing you to fine-tune your Optimum Chainring Position (OCP) with unparalleled precision. By dialing in the exact orientation of your oval chainring relative to your unique pedal stroke, you can maximize your power output, improve pedaling comfort, and reduce physiological stress. This micro-adjustability empowers you to find the perfect setup that feels most powerful and natural for you.
Designed for seamless integration, this spider is a cornerstone of ROTOR´s modular component philosophy. It is compatible with all ROTOR modular road cranks and power meters including 2INpower, INpower, ALHDU and VEGAST. This exceptional modularity gives you the freedom to build, customize, and upgrade your dream crankset over time. You can select the perfect chainring size from our 1x/2x 110×4 Q RINGS® or Round range to create a setup tailored perfectly to your riding style, gearing needs, and chosen discipline. The spider´s design accommodates both single (1x) and double (2x) chainring configurations, offering ultimate versatility.
The ROTOR Aero MAS Spider is more than just a bike part; it´s a performance upgrade that delivers tangible gains in speed and efficiency. By combining a wind-cheating design with advanced biomechanical adjustability, it empowers you to achieve new personal bests. Upgrade your ROTOR crankset today and feel the difference that superior engineering makes on every ride.
