Lezyne

Cadence Speed Flow Sensor

From pumps to lights to multi-tools, Lezyne built its reputation on an industry-leading meticulousness that has never disappointed us. Now, it brings that obsession to detail to the numbers game, letting you supplement your data-gathering with the Cadence Speed Flow Sensor regardless of what brand of head unit you're running.

As its name suggest, the Flow combines cadence and speed in one lightweight, well-articulated unit. Like virtually every head unit, it speaks Bluetooth, so it's all but guaranteed to work with your current computer. Its use of a rare earth magnet helps extend the range of engagement, eliminating the will it/won't it anxiety of the millimeter spacing between sensor arm and spokes required by other sensor suites. This lets you take full advantage of the versatile mounting and adjustable swing arm, and an LED power indicator warns when the unit needs a nap.
