4iiii Precision 2.0 3D Power Meter - 105 5800 - Certified Reconditioned


Certified reconditioned crank with brand new replacement power meter
PLEASE NOTE: This is a pre-owned reconditioned crank which may show cosmetic signs of use. The crank has been checked by 4iiii and refitted with a brand new 4iiii Precision power meter. It has undergone the same in-depth temperature and calibration tests as when originally fitted and is supplied complete with their standard 4iiii 3-year manufacturer’s warranty.

Thanks to the new 4iiii Precision 2.0 3D power meter, training with accurate power data doesn't have to cost the earth. Finally, anyone can train harder and ride faster for a podium topping performance.  4iiii claims that the Precision 2.0 3D unit is the lightest power meter on the market, perfect for those chasing every marginal gain. Weighing just 9-grams and fitting so neatly on the inner side of the standard Shimano 105 5800 crank arm; you'll barely notice it's there.

Inside the unit contains the patented 3D technology, which measures your power output to +/- 1% accuracy, via an axel strain gauge. Because of this high level of data accuracy, the 4iiii Precision 2.0 3D allows you to train with much more consistency and achieve the best possible results.  Powered by a replaceable 2032 coin-cell battery, the Precision 2.0 3D contains 100+ hours of riding and can easily be checked for remaining battery life via the dedicated 4iiii companion smartphone app. 3rd party training device and app integration are endless. As you can pair this power meter with almost every ANT+ or Bluetooth head-unit, trainer or training app, there's no need to worry about the compatibility of your new power meter with your current equipment set up.
