Dual-sided power on a brand-new Shimano Dura-Ace R9200 crankset, ready to install. 4iiii installs a PRECISION 3+ PRO sensor on each arm at the factory, so the left and right legs are measured on their own: total power, left/right balance, pedal smoothness and torque effectiveness from the first ride.

It goes on like any Shimano crankset, using the standard Shimano installation. The meter reads within ±1%, sets its terrain mode automatically, runs up to 550 hours on its battery, is sealed to IPX7 and carries Apple Find My, so an iPhone can show where the bike is when the meter is not in use.
