Rotor 3D Plus Powermeter Crankarms

Rotor 3D Plus Powermeter Crankarms

We have to hand it to Rotor. While gaining a good chunk of recognition through its Q Ring design, Rotor continues to develop some of the best componentry across the board through its extensive testing with the world's best cycling teams. This type of rider feedback is integral to the designs of its products, which makes certain that they're built to hold up to the most demanding race situations. This is the mindset that helped initiate the development of the new 3D Plus Power Crankarms, as Rotor took its proven 3D crankarm construction and combined it with some of the most accurate powermeter technology available. At only 30g heavier than its standard 3D Plus Road Crankset, Rotor's new 3D Plus Power system is one of the lightest powermeter packages available. This is due to the mating of two proven products: Rotor's 3D Plus Cranks and the MEP lab power measurement system by AIP. This 'power' half of the equation is, in fact, made possible through two independent powermeters working together on both sides of the crankset. Eight total strain gauges have been placed within the crankarms, providing a highly accurate individual left and right 'power balance' measurement. In addition to the system being ANT compatible, two new ANT protocols are measured, including torque efficiency and pedal smoothness. Torque efficiency is shown as a percentage, which measures both clockwise motion positive and counterclockwise negative movement. This 'negative torque' reading is beneficial in that it shows where you aren't properly de weighting your leg on the upstroke of the pedal stroke, thus creating dead weight. Furthering pedaling efficiency training, the system also measures pedal smoothness as a reading of your average torque versus your max torque. The power system features conveniently located battery boards on both sides, making it a user replaceable battery package. The system is driven by Rotor's proven 3D Plus road cranks. Similar to rest of the 3D line, the 3...
