ROTOR power meter set | PowerPack MTB INpower 1-way NoQ ring | Round
The Rotor PowerPacks offer you an inexpensive way to equip your bike with a power meter.
Thanks to the measurement technology integrated in the crankshaft, the INpower MTB Direct Mount does not need any visible sensors that interfere with the optics of the wheel. The weight of the system is also minimal. The INPower only weighs 560 grams (175 mm, without chainring). 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.
The power is measured using 2 pairs of counter-rotating strain gauges in the crankshaft, which measure the power of the left leg and use this to calculate the total power. 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).
Direct mount chainring | round
The matching round direct mount chainring for the Rotor Kapic crank. For a coherent overall picture, Rotor has optically adapted the chainrings to the martial design of the cranks . The chainrings also have specially shaped teeth that prevent the chain from jumping off. In conjunction with a Sram Type2 or Shimano Shadow + rear derailleur, which have a greatly increased cage preload, the chain is reliably held in position even without a chain guide.
