Product details


ROTOR power meter set | PowerPack Road INpower crank 2-fold | Direct mount oval

The Rotor PowerPacks offer you an inexpensive option to equip your bike with a high-end power meter.

Thanks to the measurement technology integrated in the crankshaft, the INpower crank does not need any visible sensors that interfere with the optics of the wheel. The weight of the system is also minimal. The INpower version only weighs 524 grams (with a crank arm length of 172.5 mm). This is made possible by the Rotors Trinity Drilling System, milled crank arms made of ultra-light aluminum 7075. The large outer diameter of the crank arms ensures the necessary rigidity. The system is powered by a long-lasting Li-Ion battery, which can be easily charged using a standard USB cable. This means that the battery can easily be supplied with energy again after a running time of approx. 300 hours. The data is transmitted using the universal ANT + protocol or via Bluetooth.

Another highlight of the system is the TORQUE 360 evaluation option. With the help of Rotor's in-house software, it can be used to analyze the torque curve during one pedal revolution. In this way, weaknesses between the left and right leg or an out of round step can be identified. This measurement technology is particularly valuable for riders who use Rotor's oval Q-ring chainrings. Using the OCA (optimized-chainring-angle) system, the software can determine the optimal position of the Q-rings via the torque curve. In this way, the driver can apply his power to the pedal even more effectively. With the proven 30 millimeter UBB crankshaft, the system in conjunction with Rotors UBB bottom bracket is compatible with all common bearing standards (except BB90 / 95).

The Direct Mount Standard is compatible with the Rotor ALDHU chainrings. These are available both as a light one-piece chainring-spider combination and as classic chainrings, which are attached to the crank using the optional ALDHU 2-way spider. Only a 10 millimeter hexagonal wrench is required to adjust and assemble the chainrings and the crank.

2-speed chainring-spider combination | oval
The 2-speed chainring combination milled from a block of 7075 aluminum is mounted directly on Rotors modular racing bike crank systems. This design with integrated spider saves 30 grams compared to the combination of spider and chainrings. The OCP system (Optimum Chainring Position) has been further refined for the optimal setting of the oval Q-Rings. Using a combination of different positions of the crank arms on the crankshaft and a fine-grained spider mount, the position of the chainrings can be adjusted in 1-degree steps.
