I've got power meters on my mind again. I have to do something to get my training on the right track. I've made a little progress, but not as much as I'd like, and think I'm capable of. Two or three people have said a power meter should be helpful if I want to learn how to ride faster in a lower heart rate zone, so maybe it's time to bite the bullet and get a power meter.
Price must be taken into consideration. There's also the choice of: hub-based units; units placed on a crank arm; and so on. I must also remember that any power meter I choose must be compatible with my cyclocomputer.
Having a power meter wouldn't do much good if I don't know how many watts I need to generate in order to simulate hills. Yesterday I rode on a Wattbike for a short time, experimenting with various resistance settings; pedaling at different cadences, etc. I was trying to reproduce the feeling my legs got while climbing those hills the previous day, so I could see how many watts it took. I also wanted to get that little test done before my muscles could completely forget how hills feel. And do they forget in a hurry!
