Bike cadence sensor Coros BCDC-BLK-V2 — wireless cadence sensor for cycling, Bluetooth & ANT+ compatibility, compact mount

The Coros Bike Cadence Sensor BCDC-BLK-V2 is a compact wireless device that measures pedal revolutions per minute to provide real-time cadence data for cycling. Designed for compatibility with Bluetooth and ANT+, the sensor pairs with bike computers, smartphones and head units to deliver continuous cadence readings during road, gravel and indoor trainer sessions. The unit mounts to the crank arm with a simple clamp-style attachment and is sized to reduce interference with normal pedaling motion while offering reliable wireless transmission for training and ride analysis.

Advantages

The Coros cadence sensor offers dual-protocol connectivity (Bluetooth and ANT+) for broad device compatibility and straightforward pairing. Its compact form factor and lightweight construction minimize impact on pedal dynamics while the crank-arm mount provides a stable position for accurate cadence measurement. The sensor is optimized for real-time data transmission, enabling immediate feedback for cadence-focused workouts and performance tracking without the need for wired connections.

Suitable for

• Road cycling cadence monitoring
• Gravel and off-road ride analysis
• Indoor trainer workouts and Zwift or other virtual platforms
• Training sessions focused on pedaling efficiency and cadence drills
• Pairing with smartphones and bike computers for ride logging

How to use

Attach the cadence sensor to the inside of the crank arm using the included clamp or mount so that it sits flush and secure without contacting the pedal or shoe. Activate the sensor according to the manufacturer’s instructions, then enable Bluetooth or ANT+ on your receiving device and perform a device search. Select the sensor from the list of available devices to pair; once paired, start pedaling and confirm cadence data appears on the paired bike computer or application. Replace the battery as indicated by the device’s status notifications to maintain uninterrupted operation.

Usage recommendations

For the most accurate cadence readings, ensure the sensor is firmly mounted and free of movement relative to the crank arm. Check compatibility and pairing method for your specific bike computer or training app before installation. Regularly inspect the mount and battery state to avoid data loss during rides.
