"Our robust ANT wireless heart rate monitor with softer, more comfortable chest strap and superior battery life eliminates cross-talk with other devices to reliably measure and send heart rate data to help you train in your zone."

Have an extra strap for when the other strap is in the wash, for another user or if your elastic strap is showing wear.

This strap is compatible with T31 coded and non-coded chest transmitters and any T series exercise equipment.

Elastic straps are used to wrap the heart rate transmitter around the chest.

Replacement battery for user changeable chest transmitter such as the Polar Wearlink chest transmitters and Polar W.I.N.D. Wearlink chest transmitters.

Great to have another while washing your other elastic strap, or just to have another on hand.

The most practical way of measuring your cycling session is with our advanced wireless cadence sensor. It measures your pedaling rate as revolutions per minute in real time and average time so you can compare the technique of your ride against previous rides.
