The most affordable crankset capable of measuring independent left/right power!
4iiii PRECISION PRO Shimano R7000 Dual-Sided Crankset
The 4iiii PRECISION PRO Shimano R7000 Dual-Sided Crankset combines 4iiii’s patent pending 3-D tri-axial strain gauge technology with Shimano’s 105 R7000 crank. The result is an accurate, lightweight and highly reliable power meter crankset that is capable of tacking the most grueling workouts or races.
The dual-sided 4iiii R7000 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 forces generated by each leg individually. In fact, this power meter is the most affordable crankset capable of measuring left/right power.
The 4iiii is also extremely lightweight, adding approximately 20 grams to the Shimano R7000 crankset. The power meter is compatible with both ANT+ and Bluetooth SMART devices and is accurate to +/- 1.5%.
- Chainrings: 50/34 | 52/36 | 53/39
- Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm
This power meter uses a 24 mm Shimano road spindle. Therefore, it is compatible with almost any bike when used with the correct bottom bracket.
