In early January, I was approached by the folks at Bryton to test a GPS of theirs, the Rider 310. More specifically, they sent me a Rider 310T, which includes a HRM strap (soft strap type) and a cadence sensor. The intended function of the GPS is for use as a basic road bike training GPS. Well, I don’t really use any GPS for its training functions, and Bryton was cool with that. I told them that the sort of riding I do is more recreational tracking with more mountain biking than road biking, and they were also okay with that.
