Cycling ANT+

Cycling ANT

Cycling ANT computers and sensors can be used to monitor your heart rate, cadence, speed and route. An ANT is a small computer system based on GPS tracking and sensory monitors. Low end ANT models are available for around £10 to £30, with top end models climbing to around £450. ANT is a technology platform owned by Garmin . An ANT computer performs a number of basic functions.

Speed Only Sensors

A speed unit uses a sensor on the wheel, held in place with a magnet. When the wheel circumference is configured, the sensor will be able to record the repeated passing of the magnet. Using this data the computer accurately calculates speed.

Cadence Only Sensor

These units measure cadence. Cadence is the speed at which your pedals are rotating. A crank is placed on of the arms connected to your pedal, and another is fitted to your cleat or shoe. Using the same magnet method as a speed sensor, a cadence sensor registers each time your foot passes the crank.

Combo Speed and Cadence Centre

Combo sensors are the most popular ANT computer. The unit delivers both speed and cadence information to your handlebar monitor. Sensors are usually mounted near to the rear wheel. Cheaper models may use wires, although more modern devices tend to feature Bluetooth or wireless technology.

Tracking

More expensive computers will track and plot your progress on a map. Devices may be able to be synced to mobiles or home computers so that data can be downloaded and analysed. Routes can often be segmented so that you can assess your performance along each section of your route. More advanced and expensive models may offer directional advice in the style of a satellite navigation computer.

ANTs are not for everyone. Some people prefer to use apps such as Strava on their phones, in which case you may be better suited purchasing a phone grip for your handlebars.
