SIGMA ROX 7.0
If you’re looking for an advanced computer that doesn’t clutter your bar, you’re spoiled for choice nowadays. Models like the Garmin Edge 25 and Lezyne Mini pack plenty of performance into a dinky package. At 73x50mm, the Rox 7.o certainly promises pint-sized GPS goodness.
The Rox 7.0 is a regular GPS computer, so no surprises here – it does the usual GPS ride tracking job we’ve all become accustomed to with little fuss. It records and shows a decent range of data – as well as speed and distance it’ll also provide you with plenty of altitude info, temperature stats and calorie estimates. It’s also able to help you out with routing.
On the road
From a purely GPS point of view the Sigma is fine – it was accurate, picked up signals quickly with little drop off. And if that’s what you want then great. But… with no ANT+ or Bluetooth connectivity you’re limited to collecting ride data.
The navigation sees you follow a simple line but you have to be viewing the map screen - you don’t get prompts in ride data screens. The Rox does support Strava live segments, but you have to plug the Rox into Sigma’s Data Center to load these, force data onto Strava, add routes, configure screens and so on. It’s an old fashioned and clunky interface that doesn’t impress compared to the instant data sharing offered by other brands. Compared to, say, the Garmin Edge 25 we can’t really see why you’d choose it.
