Sorry to steal this thread, but I'm looking into buying a computer. I do have both Strava and MapMyRide, but I figured I'd get a computer to measure cadence. The issue is which is more beneficial if you're not training for racing. Rather, more for fitness and stress relief. Do you really need a heart rate monitor? The Bontrager Node 2.1 with the DuoTrap is $200 and it includes the Heart Rate Strap, while the cheaper Node 1.1 with the DupTrap is $130 without the altimeter, grade and monitor. Is having a monitor that important even if you're not going to be racing?
