4iiii Ultegra R8000 Precision Pro Dual Sided Power Meter

With pods measuring power output from right and left sides separately, the 4iiii Ultegra R8000 Precision Pro Dual Sided Power Meter provides consistent data accurate to +/- 1%, perfect for pacing an effort on a big climb or for targetted training. The additional pods add just 25 grams to the weight of the base Ultegra crankset, and they run on commonly available CR2032 coin cell batteries. Battery life is in excess of 100 hours, and a status indicator alerts at 15% power remaining giving plenty of time to change them.

ANT+ and Bluetooth connectivity provides connection to a wide variety of devices and allows for over-the-air upgrades. The 4iiii smartphone app gives access to the rider compensation scale and other useful features.
