ROTOR INspider ALDHU Carbon Road Power Meter Crankset

The ROTOR INspider ALDHU Carbon Road Power Meter Crankset features ROTOR’s spider-based power meter paired with ROTOR ALDHU carbon crank arms! The INspider power meter is only 12 mm thick which allows it to work with even the widest bottom bracket shells, including T47 and 386 EVO.

This crankset is also highly customizable as you can select your crank arm length and chainrings. The ROTOR ALDHU carbon cranks are available with a 30 mm spindle and in a wide range of crank lengths. The INspider can be used in a 1x or 2x chainring configuration with any ROTOR 110 BCD 4-bolt chainring. Additionally, the ALDHU Carbon crank arms are exceptionally light and weigh only 260 grams.

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.

These are fantastic cranksets and are highly customizable. The ROTOR power meter measures power from both legs, is accurate and reliable.
