Cadence is a requirement for me. This unit comes with cadence, so I thought that it would work well. As if. The unit displays cadence if and when it wants. Ride a bit, reset it a couple times and it might work. And then, in the middle of the ride - no cadence. It has never been able to consistently display.The unit is trickier than a Rubik's cube to figure out. This is the first cyclometer I have ever owned that required a look a the users manual for anything other than setting the wheel size. It's like cramming for an exam before each ride, trying to figure out how each function works.4 displays?? The is room on the display for 4 functions at once. But the top one never displays. I am sure there is a method to turn it on, but I have not yet mastered that portions of the cube.
