Every effort counts with the TICKR X. Designed to help you get the most out of any workout, the TICKR X monitor tracks heart rate, calories burned, running analytics, and indoor cycling cadence. Equipped with Bluetooth and ANT+ technology, it connects to your favorite training apps, GPS watches and bike computers, supporting up to three simultaneous Bluetooth connections. Its new design makes it one of the lightest and slimmest heart rate monitors, plus the new integrated heart rate sensor and chest strap design provide a more secure connection and fit! The TICKR X even has 50 hours of onboard memory for heart rate and calorie data, giving you the freedom to train device-free.
