Sigma Pure GPS (SD03200)

The German cycling measurement tool from Sigma Sport has no wires and is securely held on the handlebar or stem even in extreme riding conditions. It is part of a cohort of mid-range cycling computers that can really do a lot.

Climb

Directly in the name of the model, emphasis is placed on the equipment of the device with a GPS module. Working in tandem with the built-in altimeter, the rider is provided with accurate information about the current altitude, in parallel with which all ascents and descents are tracked(with a percentage indication of their steepness). In addition, an arrow of the direction of movement to the starting point or a point previously set on the map is displayed directly on the cycle computer screen.

Informative display

The Sigma Pure GPS monochrome display displays information in 4 lines at once. In addition, it has a built-in backlight, so that the data is easily read at dusk or when returning from a bike trip at night. The screen informs both about the standard measured parameters (speed of movement, distance covered, travel time, number of calories burned), and about the current temperature outside the bike along with atmospheric pressure values.

Interpretation of measured data

To interpret the collected data in a form more digestible for further analysis, an NFC chip is used, with the help of which the cycling parameters are transmitted to a connected mobile gadget with a pre-installed Sigma Link application. But the owners of Apple technology will need to pair the old fashioned way — through a wired connection of the bike computer. The application maintains statistics for the last 12 months, and also calculates the total values of distance, travel time, climb and the number of calories burned. Finally, Sigma Pure GPS should be praised for its long battery life — 15 hours of operation on a single battery charge, the replenishment of energy reserves in the tanks of which takes about 2.5 hours.
