This cyclometer combines heart rate, spd, distance, time and odometer wirelessly. Even though I have set up my share of cyclometers, this required more patience and persistence than I was prepared for. Not sure why. Still, as I get more experience with it, I think it will be great to have heart rate at the ready without a watch to worry about. Cheers, M.
Small, light, HR strap is comfortable... With that said, this was the most frustrating and difficult bike computer I ever installed. Thank God, YouTube has helper videos.
