Optical armband HRM
COROS Heart Rate Monitor
A comfortable optical heart-rate armband worn on the upper arm or forearm, offering chest-strap-like accuracy without the strap. It broadcasts over Bluetooth to up to three devices at once, so it works with bike computers, watches and apps.
Highlights
Why we rate it
Strap-free comfort
Sits on the upper arm on a soft elasticated band, avoiding chest-strap chafing on long rides.
Multi-device
Bluetooth broadcast to up to three devices at once - e.g. bike computer, watch and Zwift.
Auto wear detection
Turns on when worn and off when removed, so it's ready to pair without fuss.
Washable band
The sensor pops out so the band can be washed after sweaty sessions.
