ROTOR INspider Power Meter
The ROTOR INspider Power Meter is the first of its kind – a spider-based power meter that can be used on virtually any bike! Compatible with any of ROTOR’s newer direct mount cranksets, the INspider can be used on your road, CX, gravel, MTB or track bike. In addition, ROTOR cranks come in all shapes and sizes – 24 and 30 mm spindles and crank arms from 150 to 175 mm. This allows you to run the crankset that fits both your bike and your style. You can even set up the INspider in a 1x or 2x chainring configuration using any ROTOR 110 BCD 4-bolt chainring.
The ROTOR INspider records data via four sets of opposing gauges. This results in a high degree of accuracy (+/- 1.0%) and also means the power meter can measure left and right leg power balance. The INspider also features ANT+ and Bluetooth SMART and has a USB-rechargeable battery with 200-hour battery life.
Key Product Details
Compatibility:
This power meter is compatible with any ROTOR crankset that uses a direct mount splined interface. This includes the ALDHU and VEGAST cranks for road, CX, gravel and track and the KAPIC Carbon, KAPIC and R-Hawk cranks for MTB. Regarding chainrings, it works with any ROTOR 110 BCD 4-bolt asymmetric chainring. See Compatibility tab for more information.
Power Measurement:
The ROTOR INspider power meter measures power at the spider and is therefore able to measure power from both legs.
Key Features:
Dual-leg power measurement, accurate to +/- 1.0%, 200 hours of battery life, 1x and 2x compatible, works great with oval chainrings, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility. See Specs tab for more information.
Advice From Our Staff:
This is a great way to add power to a ROTOR direct mount crankset. It measures power from both legs, is accurate and reliable. You can also run it in a range of configurations (different crank arms, spindle sizes and chainrings) to fit your needs.
