When you head out on a ride, it's helpful to have a smartphone with you for many reasons, and your phone takes on even more importance if you're using it to record your ride data on your favorite fitness app. We understand if the idea of mounting a device that does almost everything for you onto your skinny, vulnerable handlebars is nerve wracking. Wahoo's RFLKT Bike Computer will wirelessly display the ride data your phone is recording on a screen mounted to your handlebars. Meanwhile, your phone itself stays safely tucked away in your jersey pocket, protected from the elements and road debris. The RFLKT is Bluetooth 4. 0 compatible, and it will work with popular cycling apps to store your data and let you know when you've conquered a new course record right on the screen in front of you. With compatible sensors, the computer also registers cadence, and you can customize the large, backlit screen to display the fields that are the most important to you during your ride. Unlike your phone, the RFLKT computer is waterproof and shockproof, and it runs on a replaceable coin cell battery.
