Mt son and I each bought the Cateye Strada. We find that the device displays speed in 0.1 increments up to 20.0 mph, then in 0.5 increments above 20.0 mph. That's kind of aggravating when I'm working hard enough to be above 20 mph but can't tell exactly how far above 20 mph I am going. Apart from that it's a pretty good unit.
