ROTOR INspider Road Power Meter

ROTOR INspider Road Power Meter

The ROTOR INspider Road Power Meter is a spider-based power meter that is thinner, lighter and has a longer battery life than ever. The INspider is only 12 mm thick which allows it to work with even the widest bottom bracket shells. It is only 128 grams and features a 350 hour battery life. This power meter also works with any of ROTOR’s current generation of direct mount cranksets. This includes ALDHU Carbon, ALDHU and Vegast. These ROTOR cranks are available in both aluminum and carbon, 24 and 30 mm spindles and a wide range of crank lengths. This allows you to customize your crankset to fit both your bike and riding style.

The ROTOR INspider records data via four sets of opposing gauges. It is +/- 1.5% accurate and provides advanced metrics like left and right leg power balance. It is also compatible with Garmin Cycling Dynamics to provide in-depth data on your riding.  ROTOR power meters have a higher sample rate than most power meters which allows them to more accurately measure power with both round and oval chainrings. The INspider can be run in either a 1x or 2x chainring configuration using any ROTOR 110 BCD 4-bolt chainring.
