The NEW Wahoo RFLKT+ is a sleek iPhone powered bike computer just like the RFLKT, but with the added features of an ANT+ bridge, altimeter, and thermometer. The RFLKT+ uses Bluetooth 4.0 technology to connect to your iPhone and mirror your workout data from your favorite fitness App. Harness all of the power of your iPhone from your handlebars, while your phone is safely tucked in your jersey pocket. The RFLKT + uses a precision on board altimeter and thermometer to track your elevation far better than any GPS. You can use the built in ANT+ bridge to connect your ANT + power meter, speed/cadence sensor, or heart rate monitor straight to your iPhone.
