I've been riding for about a month and a half, and I have a computer without cadence or heartrate. I feel like I'm plateauing a bit, and I think it might be because my training is a bit haphazard. I don't know where my HR is at, how my cadence is, so workouts are only so-so. Can anyone suggest a computer with cadence, heartrate, and is also wireless for under or around $100? I have a cateye now and like it, but want the extra features.
