Sensor de velocidad para bicicleta GARMIN Speed Sensor 2 010-12843-30 – sensor de velocidad y cadencia inalámbrico para montaje en buje

The GARMIN Speed Sensor 2 is a wireless wheel-mounted sensor that measures real-time speed and distance without the need for a wheel magnet. Designed for unobtrusive installation on the hub, it transmits data via ANT+ and Bluetooth to compatible head units, smartwatches and mobile apps. The device records accurate wheel rotation information to support training metrics, navigation, ride logging and post-ride analysis.

Advantages

The sensor offers reliable speed and distance measurement with easy wireless pairing and broad compatibility with cycling computers and fitness devices. Its compact, lightweight design minimizes interference with wheel balance and requires minimal maintenance. Battery life and power-saving modes provide extended operation between battery changes, and the magnetless mounting reduces installation steps and accidental displacements.

Suitable for

• Road cycling and commuting where accurate speed and distance logging is required
• Training sessions that rely on consistent speed metrics for intervals and pacing
• Integration with GPS devices, smartwatches and mobile cycling apps for ride analysis
• Bikes without compatible frame mounts for traditional magnet-based sensors

Key specifications

• Wireless connectivity: ANT+ and Bluetooth
• Mounting location: wheel hub (magnet-free installation)
• Measured data: real-time speed and distance based on wheel rotations
• Power source: replaceable coin cell battery with extended runtime
• Device weight: compact and lightweight for minimal impact on wheel dynamics

How to use

Install the sensor on the wheel hub following the manufacturer's mounting method, ensuring the unit is securely fastened and aligned. Pair the sensor with a compatible head unit, watch or smartphone using either ANT+ or Bluetooth in the device’s pairing menu. Configure wheel circumference in the paired device if required for improved distance accuracy, or allow automatic calibration where supported. After pairing, start a ride activity on the head unit or app to receive live speed and distance data.

Recommendations

Periodically check the sensor mounting and battery status before rides. Replace the coin cell battery according to usage patterns and store the sensor in a dry environment when not in use. For best distance accuracy, verify wheel circumference settings in paired devices or perform a calibration ride if available.
