I love Cateye. I have the V3 on 5 bikes and was disappointed that they discontinued it. I needed a new computer for another bike, so I tried this. It arrived today and will be returned because it does not have a strap or sensor. If you do not read the description carefully, you will not know that it does not include heart rate strap and cadence and speed sensor. All you get is the useless computer. But Competitive Cyclist does provide a nice picture of the Strap and sensor that you do not get. LAME!
