Simply use your favourite app’s connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding!
Purchased this meter and it shipped right away. I stuck with the default shipping and product arrived over a week before Canada post said it would. I bought it in the 53/39 configuration because the 50/34 was slow to come back in stock. Swapped over my chainrings from my original 105 R7000 crank and I was all set. Meter works great on my Garmin Edge 1030 plus. The power number lags behind the actual mechanical input by around 2 seconds, which seems reasonable.
Awesome power meter especially for the price! Gets the job done and hold a charge for a few hundred miles! Only wish it was easier to change battery or that we could charge it
What an a**hole move to give a low rating on a product and company due to a problem that has nothing to do with the product. Mike should write a review on the Canadian Post office. Thanks for wasting everyone’s time, Mike Rende. You spoiled brat.
Can’t review a product that hasn’t been delivered. According to the Canada Post tracking, the package will arrive this Friday. I don’t think I’ve ever waited so long for a bike component that shipped from stock.
Thank you for your order. Unfortunately, it looks like your order went through some lasting delays travelling through British Columbia due to severe weather events and damage to shipping routes after major flooding in November. It has now made its way into the US and should be delivered in the next couple of days. If you have any other questions, please do not hesitate to reach out to our support team at 4iiii.com/support.

Super easy to set up and install
