Sigma ROX 4.0 vs Garmin Edge 130 Plus

The Garmin Edge 130 Plus wins 82 to 76, a gap driven mostly by ecosystem and brand credibility. Both are entry-level GPS computers, and both can do the job for a recreational rider who wants speed, distance, and basic routing. The Garmin Edge 130 Plus is extremely compact (just 33 g), has a 1.8-inch monochrome screen at high resolution (303×230 px), and includes ClimbPro — rare at this price. Battery life is 12 hours and it plugs seamlessly into the Garmin Connect ecosystem, including pairing with every Garmin sensor and Forerunner watch. The Sigma ROX 4.0 offers a larger 2.4-inch monochrome screen, 25 hours of battery (more than double!), supports GPS/GLONASS/Galileo, and is €100 cheaper. On features Garmin scores 76 vs 70, but on value Sigma wins big at 92 vs 84.

The €100 price gap (Garmin €169 vs Sigma €69) is the biggest factor here. What do you get for the premium? The Garmin ecosystem (important if you already own a Garmin watch), ClimbPro (useful on hills), and the more recognized brand with faster software updates. The Sigma has more than double the battery life and handles the basics — speed, distance, GPS track — perfectly. For a simple recreational user the Sigma just gives you more computer per euro.

For riders already in the Garmin ecosystem or who want ClimbPro we recommend the Garmin Edge 130 Plus, unless budget is decisive or you don't need map navigation — in that case the Sigma ROX 4.0 is an excellent pick that saves you €100.
