4iiii Precision 3+ Powermeter Shimano 105 R7100 12V Apple Find My

If you ride a bike fitted with a Shimano 105 R7100 12-speed groupset and are looking to take your cycling to the next level by adding a power meter, the 4iiii Precision 3+ Powermeter is the perfect choice! Integrated into the left crank arm, this power meter will provide you with all the data you need for your training sessions. The power meter is lightweight, waterproof and has a good battery life; it promises a margin of error of 1% thanks to the three strain gauges that measure all the forces of your pedal stroke.

Available in all lengths, this modern crank will help you manage your training effectively as you work towards a goal. In addition to its performance features, this sensor is equipped with the Apple Find My chip. This will help you always know where your bike is in the event of loss or theft, as it allows you to locate your bike on a map from an iPhone, iPad or Apple Watch. A real bonus built into an accessory that is more than useful for a courier.
