If you want a touchscreen bike computer with an emphasis on navigation, Garmin and Sigma should be on your shortlist, as they both make some of the best MTB GPS computers around. Most of Garmin’s touchscreen models are well over £400, with the diminutive Edge 840 starting at $449.99 / £449.00. But the recent, pared down Edge Explore 2 is only $299.99 / £249.00.
We’re going to compare it here with the same-sized Rox 12.1 Evo recently released by longtime German GPS brand Sigma. At $439.95 / £379.00, the Rox 12.1 is a chunk more expensive than the Explore 2, but it’s better specced, and still a lot less than the next Garmin up.
