Crankset with power meter on the left leg and Q-Ring Aero 50/34 oval chainrings. It quantifies the power exerted, the cadence, the effective torque, the uniformity of the pedaling, the distribution of the power according to the angle and the optimal mounting position of the Q-Rings.

Adaptable to BB30, PresFit 30, BBright, BSA threaded, ITA threaded, BB86 and EVO386 bottom bracket frames.

Set of Rotor Q-RINGS Aero oval chainrings and Rotor 3D + cranks (made of 7055 aluminum by CNC machining and with 30mm axle) with power meter on the left crank and INpower technology, integrated into the bottom bracket, being protected from shocks , water and dirt.

In addition to the lightness and rigidity of the 3D + cranks, they are joined by the latest technology in performance measurement through In Power technology that provides sophisticated, complete and precise measurements, which combined with powerful but easy-to-use software, allows us to interpret the data.

Rotor INpower begins to measure automatically when pedaling by sending the power data (measured in the left leg and multiplied by two, but being a programmable value), cadence, torque effectiveness (to know the negative torque, in quantity) via ANT + signal. and percentage) and uniformity of pedaling (round or piston pedaling).

Thanks to the TORQUE 360 graph, we can represent the polar curve of the torque, or effective force applied to the pedal, intuitively visualizing the power distribution at the different angles.

By not measuring the combined power of both legs like other systems on the market, it allows to know the complete cycle and how the power is delivered both in the lowering phase of the pedal (positive) and in the raising phase of the pedal (with a component negative, generally).

Visualizing the force polar is very useful to know the pedaling pattern and improve technique.

Another novelty provided by INpower is the OCA (Optimum Chainring Angle) which determines the angle in degrees, measured from the top dead center, in which the center of gravity of the work is located, represented in the Torque 360 graph. The OCA suggests in what position of the OCP points, mount the Q-RINGS chainrings for the highest efficiency.

All the new data offered by the INpower potentiometer is available for free on the software platforms offered by Rotor.

Another novelty presented by INpower is the use of a standard 1.5V AA battery, easy to replace, which gives it an approximate autonomy of 300 hours.

Available in 165/170 / 172.5 / 175 lengths it mounts a 110 BCD spider and 5 anchors, displaying a Q-Factor of 148mm.

Also available with 130 BCD spider and 5 screws; check availability.

With a 43.5mm chainline, they are compatible with BSA, ITA, BB86, BB30, BB30A, PF30, BBRight, BB386 Evo bottom brackets

Oval Q-Ring chainrings give your performance a boost by modifying pedaling resistance based on the natural strength and weakness of your legs. They make better use of the strongest muscle groups (increasing positive work) and compensate for the weaker areas of the pedal stroke (reducing negative force), which is commonly known as deadlock.

Using the OCP technology and its different positions, we can adjust the point of greatest ovality of the Q-Ring to match our maximum torque, thus minimizing the dead center of the pedal stroke (the moment in which a pedal is at the upper maximum point and the other in the lower one, no force is generated on the connecting rods).

100% CNC machined from 7075-T6 aluminum, in this Aero version they benefit from a not inconsiderable better aerodynamics and a very attractive aesthetic.

Compatible with groups of 9, 10 and 11 speeds.

Crank weight without battery: 525gr. (170mm)

Weight of the Q-Ring plates: 173 gr. (50 / 34D)
