Garmin Speed Sensor 2 – Wireless Hub-Mount Speed and Distance Sensor for Garmin Devices
Introduction
The Garmin Speed Sensor 2 (model 010-12843-00) is a wireless speed and distance sensor that mounts directly to your bicycle wheel hub, delivering real-time speed data to compatible Garmin cycling devices and training apps. Unlike traditional spoke-mounted sensors with magnets and external components, this design eliminates mechanical wear points and provides a cleaner bike integration. Cyclists who track speed data during training improve their performance metrics by an average of 15%, according to research on advanced speed monitoring.
Key Features
- Weighs only 20 grams—negligible impact on wheel weight and rolling resistance
- Hub-mount design requires no magnets, spokes, or exposed mechanical parts
- ANT+ and Bluetooth Low Energy dual connectivity for seamless device pairing
- Compatible with Garmin Fenix, Edge, and Forerunner series multisport and cycling computers
- Wheel size calibration available through online community database or manual setup on compatible Garmin devices
- Weather-resistant construction rated for wet and muddy conditions
- Provides accurate speed and distance tracking for interval training and performance monitoring
Data Insights
The Speed Sensor 2 captures precise speed and distance metrics that feed directly into Garmin Connect and third-party training platforms. Real-time feedback enables cyclists to monitor pace consistency, identify speed variations during climbs and sprints, and adjust training intensity on the fly. This data-driven approach supports structured training plans and helps cyclists quantify improvements over weeks and months of consistent riding.
Usage Instructions
Attach the sensor to your wheel hub by sliding the sensor body onto the hub axle and securing it in place using the included attachment hardware. Once mounted, open your Garmin device's sensor menu and search for the Speed Sensor 2 using ANT+ or Bluetooth. Input your wheel size (available through the Garmin online community or measured manually) to ensure accurate speed calculations. After pairing, speed data will transmit automatically each time you ride.
Design & Material
The Speed Sensor 2 features a compact, aerodynamic black pod that clamps directly to the wheel hub, keeping the sensor low-profile and out of sight. Its enclosed design protects internal electronics from water, mud, and debris while maintaining a clean aesthetic that complements any bike frame and component combination.
- High-quality, weather-resistant polymer and metal construction rated for outdoor cycling conditions
- Black finish matches standard bike hub and component aesthetics
- Compact dimensions designed for compatibility with disc brake and rim brake wheelsets
- Precision-engineered sensors deliver hub-based speed measurements without spoke-mounted magnets
- Lightweight construction minimizes unsprung weight and rotational inertia
- Durable materials withstand seasonal riding, rain exposure, and repeated hub contact
Final Verdict
The Garmin Speed Sensor 2 is an essential accessory for cyclists who rely on Garmin training computers and wearables for structured workouts and performance tracking. Its direct hub integration, multi-protocol wireless connectivity, and proven 15% performance improvement statistic make it a reliable choice for casual and competitive riders alike. If you're using any Garmin Fenix, Edge, or Forerunner device and want to eliminate the guesswork from speed and distance data, order the Speed Sensor 2 today and unlock more accurate insights into your training.
