Why We Like The Shimano 105 R7000 Precision 3 Left-Side Power Meter

When improving comes down to gathering the nitty-gritty details and numbers, it's best to let the Shimano 105 R7000 Precision 3 Left-Side Power Meter do the work. This way, we can push our limits knowing every pedal stroke is measured for optimal performance. It's one of the lightest power meters on the market at 9 grams with a 5.5mm design accommodating the tightest of tolerances between crank and chainstay. This power meter also measures readings accurately to +/-1.0%. The coin cell battery offers up to 800 hours of life, which gives us plenty of time to scrutinize multiple rides to come before a recharge is required, and it connects easily to the 4iii app on our phone via ANT+ or Bluetooth SMART.
