Frequently Asked Questions
Phone vs. Dedicated GPS?
Phones have better screens but poor battery life and fragility. Dedicated GPS units (Garmin/Wahoo) are rugged, readable in sun, and last 20+ hours.
Do I need paper maps?
Always carry a backup. electronics fail. A paper map doesn't run out of battery.
What is best for route planning?
Komoot offers excellent surface type analysis. RideWithGPS has superior route editing tools. Heatmaps on Strava help verify if a road actually exists.
Touchscreen vs. Buttons?
Touchscreens are intuitive but struggle in rain or with gloves. Buttons (like on the Wahoo ROAM) are reliable in all weather conditions.
