Rotor 3D+ powermeter crankset with over Q-Rings chainrings.
53-39, 11 speed, 130 BCD.
Crank arm 172.5 mm. ATN+
Good battery life, consistent accuracy. Housed within the axle, the AA battery provides up to 300 hours of use and is easy to replace - the locking cap is opened by hand. Compatible with most frames. Q Rings chainrings will improve your performance, minimize fatigue and reduce stress on the knees. Their oval shape virtually decreases the gear ratio in the dead spot and increases the gear ratio in the power phase where the rider exerts the most force.
Used, in great condition.
$450 obo.
