Wahoo TRACKR SPEED Cycling Speed Sensor

Wahoo TRACKR SPEED Cycling Speed Sensor is a compact wireless sensor for measuring bicycle speed during training and everyday rides. Its replaceable CR2032 battery provides up to 200 hours of operation before a battery change is required. The housing carries an IPX7 water-protection rating, making the sensor suitable for riding in wet conditions. During a ride, it supplies real-time speed readings for performance tracking and training records. Recorded speed data can also contribute to logs of routine journeys and recreational rides.

The 13 g sensor measures 35 x 32 x 18 mm, giving it a compact form factor at the wheel hub. It attaches to the bicycle's front hub, where it detects wheel movement without requiring a magnet. With no separate spoke magnet, there is no additional sensor component to position or align. This hub-mounted arrangement is described as suitable for most bicycles. Compatible cycling computers can receive the transmitted speed feed for display and ride recording.
