CatEye Strada Smart Monitor. If you're the type of person who brings a smartphone along on every ride then the CatEye Strada Smart is just the cycling computer for you. Via the CatEye Cycling app loaded to your smartphone and your smartphone's GPS capability, ride data is collected and mirrored in real time on the Strada Smart head unit through Bluetooth. All this takes place as your phone is in sleep mode, safely tucked away in your pocket and preserving battery power. And the Strada Smart doesn't only display ride data, but as your smartphone receives email or calls, alert icons are also displayed in real time. For true data aficionados, the Strada Smart can also be paired with Bluetooth Smart enabled speed, cadence, heart rate, and power sensors sensors not included for an incredibly rich, potent feedback on your riding performance. Data is collected on your smartphone, and once a ride is complete all of the data is uploaded from the app with a simple touch of a button to CatEye Atlas, Strava, and TrainingPeaks. Genius!
