You have your ANT+ device, but now, how do you get all your metrics to show up on it? Sure, that old wired speed and cadence sensor works fine during the ride, but once it's over, you have no record of those KOM breaking speeds you rode. CycleOps' ANT+ Dual Speed/Cadence Sensor gives you the information you crave, right at your fingers. This compact sensor attaches to your bike near the rear wheel and the crankset. Once the magnet is added to the crank, it picks up your speed and cadence and transmits it to your device of choice. From here you can use the information any way you see fit. It may be used indoors on a trainer or outside on the road. The Cycleops ANT+ Dual Speed/Cadence Sensor is available in one size and color and is compatible with any ANT ready device.
