4iiii PRECISION 3+ Powermeter For SHIMANO 105 FC-R7000

Compressed into a small and lightweight package, the PRECISION 3+ power meter features the most powerful measurement technology currently available in the 4iiii range, making it an excellent choice for professionals and weekend warriors alike when it comes to wattage-based training control.

In the Ride Ready version of the PRECISION 3+ power meter, you get a left crank arm with ready-to-use installed watt measurement technology in a selected length for your existing SHIMANO 105 FC-R7000 crankset. For the installation, simply replace your existing crank arm with the watt measuring crank arm. The installation corresponds to the SHIMANO standard process for HOLLOWTECH II cranksets and can thus be completed in a few simple steps. Afterwards, simply connect the power meter to your favourite training device and you’re ready to go!

With +/- 1% accuracy, a battery life of up to 800 hours, automatic temperature equalisation, automatic terrain detection and support for the Apple Find My feature on iPhones, the 4iiii PRECISION 3+ power meter leaves almost nothing to be desired.

Highlights:
• Apple Find My support:
The Apple Find My technology is integrated directly in the PRECISION 3+ power meter. By using the Apple network with over 1.5 billion users worldwide, you can keep an eye on your bike’s location with your Apple devices. A very practical safety feature.
• Battery life:
With up to 800 hours of battery life, you won’t have to worry about changing your battery for a very long time. And if the battery does run out at some point, the built-in CR 2032 value cell can be replaced quickly and easily.
• Accuracy in 3D:
Nobody has the perfectly round pedal stroke! 4iii uses 3 strain gauges on the PRECISION 3+ power meter to measure all forces in your pedal stroke.
• Automatic terrain selector:
The PRECISION 3+ powermeter automatically detects the terrain you’re riding on for a better quality of the cadence and power data.
• Ultra Low Profile:
With an ultra low profile design of approx. 5.5 mm, the PRECISION 3+ power meter requires very little space, despite being attached to the inside of the crank. It is thus easily compatible with most bike frames.
• Light Weight:
With approx. 9 grams of additional weight compared to your standard crank without watt measurement, the PRECISION 3+ powermeter weighs about as much as a sip from your water bottle.
• Waterproof rating:
With an IPX7 waterproof rating, the PRECISION 3+ can handle the toughest conditions.
• Indoor training:
If the weather doesn’t play along, you can connect your 4iiii powermeter via ANT+ or Bluetooth Smart (BLE) with all common indoor training apps such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy and use it on the roller trainer.
