Ultegra R8000 Bluetooth Single Leg Power Meter Crank Arm

So you've read enough training articles and heard enough babbling from your riding partners to know it's time to get a power meter. If you're lucky enough to already own Shimano Ultegra, you need to know that Pioneer offers its Ultegra R8000 Bluetooth Single Leg Power Meter Crank Arm that lets you get the metrics you're after at a relatively inexpensive price point. This updated version of the Pioneer R8000 Crank Arm gets ANT+ and Bluetooth compatibility so you can play with more apps, phones, and head units. Already proven in the pro peloton, the meter is the fruit of Pioneer's continuous development bringing the ability to chart power to the masses. And if you want to really nerd out later, you can always add the drive-side power meter to the party for dual leg readings.

This crank arm-mounted power unit uses strain gauge technology to measure pedaling force, direction, and overall efficiency, meeting the industry benchmark of +/- 2% accuracy. The power meter sports a sleek profile that resides on the inside profile of arm, adding just a few grams bringing the total weight to 220 grams. As you pedal, sensors capture 12 points of rotation at 30-degree intervals, taking a measurement 16 times per capture point for greater accuracy. As you're checking the Pioneer or other capable head unit mid-ride, you'll find the heading "pedaling efficiency," which is a combination of force measurements that together provide the total power output for each crank rotation. Ultimately, this means Pioneer is able to deliver a single accurate measurement that considers the entire pedal stroke with this crank arm-based power unit.

Training and racing with fluctuations in temperature and rising elevation figures often wreak havoc on power meter accuracy. Understanding this burden on traditional power meters, Pioneer addresses this problem with Zero Point Calibration with Active Temperature Memory Adjustment. This technology allows the power meter to anticipate and adapt to environmental changes, so you won't have to kill your momentum mid-ride while you freewheel to let the unit zero out.

It's fully compatible with ANT+ and Bluetooth head units, making pairing a seamless affair with your favorite cycling computers and fitness apps. To further analyze each of the 12 force vectors individually, Pioneer's newest HDPower Metrics and Cyclo Sphere program works in tandem with Pioneer cycling computers. It's worth noting that although it's intended to seamlessly pair with your Ultegra R8000 crankset for a perfect fit and finish, it's perfectly compatible with Shimano's 6800 crankset if you don't mind the less-than-perfect match.
