Well, he also brought up Ulrich, and the fact that not everyone is comfortable going at the specific cadences that are generally considered correct. I had told him I was going to use it for training purposes, to make sure my cadence stayed around 90-120, and that's what he told me. I tend to believe him because he's been riding for a very long time and is a strong rider, he owns two bike shops, and he took the time to pursuede me to buy a cheaper item than the one I originally intended to get.

Sure a car has a tach, but you're body isn't the thing powering it. If you're not in tune enough with your body to figure out when you need to shift, you're relying too much on your computer.

I second the Planet Bike Protege 9.0...everything you need on the display at the same time...got mine from JensonUSA.com. They sell them for $20 which is the cheapest I ever found it online, most other places charge around $30
