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.
