Rotor INspider ALDHU Powermeter Crankset – 24mm | Oval

More flexibility through the modular system

The Rotor INspider is a powermeter for all types of bikes, from road bike to MTB. The modular system allows a quick change and provides the necessary flexibility. Together with the lightweight ALDHU crank arms and oval aero chainrings, this combination is aimed primarily at road cyclists and triathletes.

The INspider has a rechargeable battery and coated electronics and is IPX7 water resistant and sealed accordingly. The power of the two legs is determined inside the spider via 4 counter-rotating strain gauges. The recorded data of power, cadence and TORQUE 360 provide the necessary values for the optimal chainring angle (OCA) as well as the optimal chainring position (OCP).

The ALDHU crank is equipped with OCP Mount technology, which allows the rider to fine-tune the alignment of oval Q-Rings chainrings in 1-degree increments. The diameter of the shaft is 24 mm.

The oval chainrings are compatible with all Rotor cranks with BCD110x4 spider or INspider powermeter and offer fast and precise shifting, attractive weight and a more aerodynamic and aggressive look.
