Description

4iiii PRECISION PRO Shimano R7000 Dual-Sided Crankset

The 4iiii PRECISION PRO Shimano R7000 Dual-Sided Crankset combines 4iiii’s patent pending 3-D tri-axial strain gauge technology with Shimano’s 105 R7000 crank. The result is an accurate, lightweight and highly reliable power meter crankset that is capable of tacking the most grueling workouts or races.

The dual-sided 4iiii R7000 crankset also features independent left/right power measurement. With a power sensor located on the inside of both crank arms, the power meter can measure the forces generated by each leg individually. In fact, this power meter is the most affordable crankset capable of measuring left/right power.

The 4iiii is also extremely lightweight, adding approximately 20 grams to the Shimano R7000 crankset. The power meter is compatible with both ANT+ and Bluetooth SMART devices and is accurate to +/- 1.5%.

 

Options

  • Chainrings: 50/34 | 52/36 | 53/39
  • Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm

 

Compatibility

This power meter uses a 24 mm Shimano road spindle. Therefore, it is compatible with almost any bike when used with the correct bottom bracket.

Please note, this product requires a Shimano Crankarm Cap Tool (sold by us separately) for installation.

    Despite the item being back ordered they arrived shortly after the order was placed. Installation was easy and so far they have been working without any issues. It is recommended to calibrate them before each ride which only takes a few seconds. Seems like excellent value compared to other brands.

    So far, so good. Did a power comparison on a ride on the Wahoo Kickr Snap and observed a 3% difference. Easy to calibrate, make sure to have all the firmware updated. If you want the R/L ratio data, make sure to have the R and L paired in the 4iiii app before connecting to Wahoo Element

    As a Canadian, there has to be a good reason to order things internationally. Rest assured, Power Metro City has the goods. First off, the website is a great resource to those considering power meter options. Second, selection was better than anything in Canada. Third, price was pretty comparable and usually better. Bit with the pandemic, sourcing power meters is even harder. So I’m glad Power Meter City came though. It shipped out very fast. Unfortunately, there were delays (outside of the company’s control). But when I reached out for a status update on where the unit was, Power Meter City was responsive (answering the same day!). I now have the unit. It is as advertised. And free shipping made it actually cheaper than if I bought it domestically!

    5 stars! Great experience.

    And yes, the unit works great too. Though there are some online rumblings about left-right balance accuracy/reliabilty with Shimano power meters. Works well enough for me. Cheaper than pedals. No complaints here!

    Great communication and quick painless delivery. I was a little apprehensive about ordering from California to Ontario Canada so the delivery process was easier and quicker than I expected.
    The power meter itself has been very good so far. The iPhone app was a bit finicky in getting both left and right sensor updated to the latest firmware, but was still a quick enough process, and everything has been smooth after that.
