ROTOR INspider ALDHU Road Power Meter Crankset

ROTOR INspider ALDHU Road Power Meter Crankset

The ROTOR INspider ALDHU Road Power Meter Crankset is the first of its kind – a spider-based power meter that can be used on virtually any bike! It is compatible with any of ROTOR’s newer direct mount cranksets and you can use it on your road, CX, gravel or track bike.

In addition, ROTOR cranks come in all shapes and sizes. You can select 24 and 30 mm spindles and crank arms from 150 to 175 mm. This allows to you 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%). It also means the power meter can measure left and right leg power balance. The INspider features ANT+ and Bluetooth SMART and has a USB-rechargeable battery with 200-hour battery life.

More Affordable VEGAST Crank Arm Version: We also sell the ROTOR INspider VEGAST Road Power Meter Crankset which comes with more budget friendly crank arms. The VEGAST crank arms are not quite as nice and they are a bit heavier.
