Heart rate is one of the most valuable training metrics for cyclists — training in specific heart rate zones allows you to manage effort, build aerobic fitness efficiently, and avoid overtraining. A chest strap HRM provides more accurate and responsive heart rate data than optical wrist-based sensors, particularly during high-intensity efforts and intervals where wrist sensors can lag or lose accuracy.\u003c\/p\u003e\n\n\u003cp\u003eThe sensor module attaches to a \u003cstrong\u003esoft, elastic chest strap\u003c\/strong\u003e that is both \u003cstrong\u003ewashable and replaceable\u003c\/strong\u003e — the strap can be removed from the sensor module for washing, maintaining hygiene during regular use. The sensor is \u003cstrong\u003esweat-proof and IPX7 waterproof\u003c\/strong\u003e (1 metre for 30 minutes), making it reliable in all training conditions.

It is not limited to Bryton devices.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy is a chest strap more accurate than a wrist-based optical sensor?\u003c\/strong\u003e\u003cbr\u003eOptical wrist sensors measure heart rate by detecting blood flow through the skin using light. This method can be affected by movement artefacts, skin tone, wrist position, and strap tightness, and can lag during rapid heart rate changes. A chest strap uses electrical signals (ECG-based detection) to measure heart rate directly, providing faster response and greater accuracy — particularly during high-intensity intervals, sprints, and efforts where heart rate changes rapidly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I wash the strap?\u003c\/strong\u003e\u003cbr\u003eRemove the sensor module from the strap by unclipping it. The elastic strap can then be hand-washed with mild soap and water and allowed to air dry. Do not machine wash or tumble dry. The sensor module itself should be wiped clean with a damp cloth — do not submerge the module beyond its IPX7 rating.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this the same HRM included in the Bryton Sensor Bundles?\u003c\/strong\u003e\u003cbr\u003eYes — this is the same Smart Heart Rate Monitor included in the Sensor Bundle variants of the Bryton computer range. If you purchased a Device Only variant and want to add heart rate monitoring, this is the sensor to buy.
