Bike computer vs. watch
A dedicated bike computer offers a larger screen, better GPS accuracy on the bike, and easier data visibility while riding. Your watch can replace it for basic needs, but a bike computer is a worthwhile upgrade.
Many triathletes use both: a watch for swim/run and a bike computer for cycling.
Key features
GPS tracking, speed/cadence display, heart rate connectivity, and navigation are core features. Advanced models add power meter support, training plans, and color mapping.
For triathlon, ensure your computer can pair with your heart rate monitor and any power meter you might use.
Popular models
Garmin Edge series (540, 840, 1050) dominates the market. Wahoo ELEMNT BOLT and ROAM are praised for simplicity. Hammerhead Karoo 3 offers a touchscreen experience.
All are excellent choices. Pick based on budget and feature preferences.
Setup and mounting
Mount your computer in front of your handlebars for easy visibility. Use a quarter-turn mount for security. Set up your data screens before riding so you can see the metrics that matter during training.
