Product details

Thanks to new and more efficient hardware, it has a battery life of up to 41 hours. With the help of barometric measurement, it reliably provides information about altitude, determines inclines and declines and thus enables precise recording of the route. The high-contrast display with its 2.4-inch diagonal and large digits is easy to read even while travelling. It reliably displays navigation instructions and data such as altitude profile, speed, distance and training time and can also be connected to e-bikes and external sensors. The free Sigma ride app is an important addition to the Sigma GPS bike computer, collects your successes and helps you achieve your personal goals.

The Sigma has an easy-to-read display and comprehensive connectivity. The workmanship is of high quality. The route guidance is sometimes misleading and the operation is not intuitive. There is no protection for the speedometer.

    The Sigma ROX 4.0 ENDURANCE is a reliable bike computer with good features, simple operation and solid navigation. We were particularly impressed by the long battery life, the simple set-up and the option to customise the display functions.
