  • Rotor INpower Flow MAS Power Meter Crankset

Equipped with alternative bolt hole placement alongside the standard placement, it allows you to find positions between the optimum chainring position of the Q-Ring to suit your personal riding style. Keep on top of your outputs as you look to make gains with this fantastically efficient Rotor crankset.

    • MAS (Micro Adjust Spider) Technology: The new Micro Adjust Spider (MAS), offers more positions to suit every rider’s needs. Their new advanced MAS spider has an alternative bolt hole placement, as well as the standard bolt hole placement (see image below), allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the Q-Ring. A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment. The MAS spider when used with Q-Rings offers half positions giving approximately 2,5 degrees. This means that you can micro adjust the position of your Q rings, to suit your riding style.
    • Integrated Electronics Inside: Electronics and battery are integrated inside the axle, making INpower shock and contaminant resistant, and waterproof with cleaner data transfer. 
    • Tool-Free Battery Replacement: INpower uses a standard AA battery that typically lasts 300 hours when fully charged. A rechargeable AA battery can also be used. 
    • Compatible with all ROTOR 30mm Cranks: INpower’s axle-based technology offers a wide range of cranks for both road and off-road riding.
