What do I mean by ANT+ profiles/device types? Well, every ANT+ device has a profile, think of it like a ‘classification’.

For example, the Garmin FR305 doesn’t support these newer ANT+ profiles. Meanwhile, the speed-only and cadence-only sensor types are newer and far less supported. I know of no ANT+ devices that fail to support it. The combo sensor type was the oldest, and is the most widely supported. It’s simply a combination of the first two unit types I noted.Įach of these different devices uses a different ANT+ ‘profile’ type, which means that just because a device supports one profile type, doesn’t mean it’ll support the other types. This unit type sends both speed and cadence information wirelessly to the head unit, and does so usually using a single device (either one piece physically or two small pieces connected via wire) mounted near the rear wheel.

Each time your crank arm passes the sensor a single revolution is recorded.ģ) Speed/Cadence Combo Sensor: This is by far the most popular type. The crank is the arm that the pedal connects to (and in turn, your cleat then shoe then foot). Because the wheel circumference is known (manually entered, or calibrated via GPS), each time the magnet passes the sensor a simple mathematical calculation can be made to determine overall speed and distance.Ģ) Cadence Only Sensor: This unit uses a cadence sensor on your frame and a magnet on your crank to measure cadence.

You have:ġ) Speed Only Sensor: This unit uses a wheel sensor and magnet that’s mounted on the frame with a magnet on the rear wheel to measure speed and distance. Well, there’s actually three different ANT+ sensor types related to this area, which align to the three different official ANT+ sensor device profiles for speed & cadence sensors. Thankfully, the speed/cadence sensor is actually a bit less mysterious than the footpod, primarily because it’s a very mathematically simple device (unlike the footpod which calculates distance based on a number of calibrated factors).

After the popular ‘everything you ever wanted to know’ post I did back this winter on the footpod, I decided it was time to continue the series with the Speed/Cadence sensor.
