SO GOOD
Coming complete with a heart-rate monitor and speed and cadence sensors, the CatEye represents pretty good value for a GPS unit. ANT+ technology connects everything wirelessly and allows additional sensors such as power meters to be added.
Average and maximum values for heart rate, speed and cadence are recorded – great for fitness fans. It’s easy to reset the two trip meters, and the screen is big and clear. The mount fits on both 31.8mm and 35mm handlebars too.
NO GOOD
It’s not cheap, the single main button makes scrolling through functions tedious and it doesn’t count calories.
Price 270$ with sensors
