Rotor InPower 3D+ Power Meter - Complete Chainset (No Rings)
Available to Order
New innovative crank axle-based power meter from Rotor. All electronics are integrated inside the bottom bracket, protecting it from shock, crashes and the outside elements. INpower measures power in the left leg (single sided) only.
Every power meter purchase from Bike Science Bristol includes a FREE Level 2 Performance test to accurately determine your power training zones.
This complete Rotor 3D+ chainset offers exceptional stiffness and light weight (just 525g for cranks including power meter electronics).
Now for the first time, with a nod to toward ROTOR's flagship Q-Rings, INpower features TORQUE 360 and Optimum Chainring Angle (OCA) pedal analysis. Cyclists can now precisely and accurately assess force variations in their pedal stroke. TORQUE 360 and OCA values enable riders to orient their Q-Rings around their distinct pedaling characteristics taking advantage of their most productive zone. This service is offered free of charge to any customer purchasing an InPower power meter and Q-Rings from Bike Science Bristol
INpower uses a standard AA battery and is equipped with the UBB30 axle system, a 30mm diameter axle, compatible with almost all standard frames on the market. Because it's centered in the crank axle, INpower achieves cleaner data transfer and greater accuracy via ANT+ protocol without suffering interruptions and temperature fluctuations. Sophisticated metrics like Torque Effectiveness and Pedal Smoothness determine total torque versus positive torque and average power versus maximum power respectively.
