Most top cyclists use a Wattage measuring device as a training tool these days. There are a number of systems out there, but the one we recommend for anyone from enthusiastic amateurs to aspiring pros is the Powertap Pro+. The kit is $1199.99 at The Cyclery.
The new black PowerTap is lighter and the electronics are arranged a little differently. I haven't actually used one yet so that's all I know so far. Cyclingnews has a good article on the new PowerTap.
