Ok I really don't have a clue on this, but I want to get a heart rate monitor and start training a bit more seriously. Currently I just use a Smartphone whilst out riding, so a bike computer would be handy, but then it would be good to be able to take it running too.
Id also like to be able to use it on the Turbo too, so I guess the option to buy cheap secondary cadence sensor and bracket is a consideration.
Am I asking too much?
Do things like Garmin Edges do this? I'm not too bothered about mapping, and I assume that's what your paying for on a Garmin?
