Cycling just isn't smart without heartrate monitoring, so CatEye built its Bluetooth HR Sensor to pair with BLE-enable cycling apps in order to pump out more training data while you're pumping out the watts.
A heart rate monitor strap for charting your zones
Pairs with any BLE-enabled smart phone cycling app
Strap is comfortable even when you're in the pain cave
Familiarity: I returned this product before using it
The site doesn't show it, but this is Model # HR-12 with Bluetooth Smart, so it did not work with my computer. The rating is based on the inadequacy of the listing, not the product, which I could not use to evaluate.
