About the 4iiii PRECISION Shimano DURA-ACE 9100 Dual-Sided Crankset

The 4iiii PRECISION Shimano DURA-ACE 9100 Dual-Sided Crankset combines 4iiii’s patent pending 3-D tri-axial strain gauge technology with Shimano’s top-end DURA-ACE 9100 crankset. The 4iiii PRECISION DA 9100 Dual-Sided Crankset also features independent left/right power measurement. With a power sensor located on the inside of both crank arms, the power meter can measure the force generated by each leg individually.

In addition to +/- 1.0% accuracy and dual ANT+ and Bluetooth SMART compatibility, the 4iiii PRECISION is extremely lightweight, only adding approximately 40 grams to the Shimano DA 9100 crankset. The 4iiii PRECISION uses a coin cell 2032 battery with a 100-hour battery life.
