Product details


B-Ware - What is it?

As B-Ware (second choice) we refer to products that can no longer be sold as new goods. The products mostly come from customer returns and are therefore offered at a special price. Before we offer an item as B-stock, it is checked for functionality and completeness. The purchase of a B-Ware article is not a risk. The statutory liability for material defects remains in effect, as does the right of withdrawal.

Condition: item unused; minimal traces of assembly on the crank arms, stronger traces of assembly on the
lockring tool; without original packaging

ROTOR Crank INPOWER Road Direct Mount

With the INPower, the Spanish component manufacturer Rotor supplies the most discreet and at the same time most versatile power measurement system on the market. Thanks to the measuring technology integrated in the crankshaft, there are no visible sensors that would disturb the optics of the wheel. The weight of the system is also minimal. The INPower version weighs just 524 grams (with a crank arm length of 172.5 mm). This is made possible by crank arms milled out of ultra-light aluminum 7075 using Rotor's Trinity Drilling System. 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. The battery can thus be supplied with energy again after a running time of approx. 300 hours without any problems. 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, the torque curve during a pedal revolution can be analyzed. In this way, weaknesses between the left and right leg or an uneven step can be detected. This measurement technique is particularly valuable for riders who use Rotor's oval Q-ring chainrings. The software can use the OCA (optimized-chainring-angle) system to 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 is compatible with all common bearing standards (except BB90/95) in conjunction with Rotors UBB bottom bracket.

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 that are attached to the crank via the optional ALDHU 2-way spider. Only a 10 mm 6-point key is required to adjust and assemble the chainrings and the crank.
