PRECISION’s left side power meter leads the industry with its lightweight, compact design. PRECISION is a highly accurate and affordable crank-mounted bicycle power meter. With its proprietary strain gauge layup, PRECISION delivers real-time power output in watts, cadence data and is both ANT+ and Bluetooth Smart compatible. 3D power meter technology (patent pending) is capable of measuring tri-axial strain on your crank.
PRECISION also distinguishes itself with its easy to access coin cell battery and over-the-air upgrades via both iOS and Android.
