Product Details The main feature is the 2.3-inch high-definition monochrome display using optical adhesive material, which suppresses screen glare, allowing you to clearly see information from any angle without worrying about sunlight reflection or shadows. Since it has a built-in GPS, basic data such as speed and distance can be measured with the device alone. Of course, by using it with various sensors compatible with standards such as Bluetooth and ANT+, you can also display cadence, heart rate, power, etc. It supports not only GPS but also five different satellite positioning systems: Glonass (Russia), BeiDou (China), Galileo (Europe), and Michibiki (Japan), enabling accurate data measurement worldwide. It supports more than 72 types of data, including time, speed, distance, calories, cadence, altitude, and heart rate, and can display up to 8 items on one page. It also supports 31 items of power-related data, so it can make your daily training more efficient depending on how you use it. A dedicated smartphone app is also available, allowing you to customize the display screen smoothly, and smart notifications that notify you of email reception, etc., are also displayed if connected to your smartphone via Bluetooth. The operating time is as long as 35 hours, so you can use it without worrying about running out of battery even on long-ride events or 400km brevet rides.
