4iiii Precision 2.0 3D Power Meter – 105 R7000 – Black

You’d be hard pressed to find a pro cyclist not training with a power meter these days, even among amateurs they are common place. For good reason too, power meters are easily one of the most effective ways to enhance your cycling performance. Plus, the simplicity and affordability of 4iiii’s Precision 2.0 power meter, installed on Shimano’s 105 R7000 crank, means unlocking your wattage potential has never been easier. Accurate, Lightweight, Reliable In the Precision 2.0, the Canadian sports-tech company measures power output, through a proprietary tri-axel strain gauge in the left crank arm, as you pedal. What’s remarkable is 4iiii offers an industry-leading accuracy of +/- 1%, but the device’s presence adds only 9 grams to the standard weight of a crank arm. Even the most gram conscious bike riders’ can’t quibble with that! Combining accuracy, low weight, and a low cost the Precision 2.0 power meter is easily one of the most cost effective, accurate, and reliable ways to start training with power. What’s more, the only difference between this product and a more expensive Dura-Ace version is the crank arm it’s attached to, meaning you are literally getting pro-level technology at a more palatable price point. The Set-Up The device couldn’t be simpler to install either. It arrives pre-fitted to the inside of a brand-new 105 R700 crank arm, all that’s required from you is fitting it to your bike like a regular crank arm. No special tools or elaborate configuration required. What’s more, being located on the inside of the crank arm, the Precision 2.0 is barely noticeable. Add in a ride-time battery life of over 100 hours, and it may be quite some time before you ever do have to pay it any attention. Battery life can be monitored via the iOS and Android app, and when battery replacement comes around, it’s simply a case of replacing the 2032 coin-cell battery, no tools required. As you would expect from a modern piece of cycling tech, it is compatible with most ANT+ and Bluetooth capable devices, meaning you’ll be able to sync it to your chosen bike computer, indoor trainer, and/or laptop/PC, and use it for training and racing indoors and outdoors. Whether you’re merely curious about the watts you’re cranking out or you’re looking to pace yourself up your favorite climb, then the 4iiii Precision 2.0 will make a great addition to your bike.
