4iiii PRECISION Shimano Ultegra R8000 Dual-Sided Crankset

 

The 4iiii PRECISION Shimano Ultegra R8000 Dual-Sided Crankset combines 4iiii’s patent pending 3-D tri-axial strain gauge technology with Shimano’s best-selling Ultegra R8000 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 R8000 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.

The 4iiii is also extremely lightweight, adding approximately 20 grams to the Shimano R8000 crankset. The power meter is compatible with both ANT+ and Bluetooth SMART devices and is accurate to +/- 1.5%.
