Are you using a cadence sensor?

If not, suggest you pick up a computer. I'm using a wired Cateye Strata (SP?).

It has helped me a lot,

I'm 65, have been biking only a couple of months.

I started out faster, probably because I was running fifteen or twenty mile a week.

Even so, got a new bike, had them put a computer with cadence - Almost all of the time, I have it on the cadence screen.

It helps me realize if I'm loafing, helps me stay in my best "power bandwidth" and have increased my cadence to 85 - 90 range.

Helps me extend my range in a particular gear, pick shift points better, etc.

Great training tool for me.

I don't worry about what I read on the forum, etc, not trying to reach a particular spin, etc.

But I am using it to be a better rider, and it's a tool that makes my training better, and helps me enjoy riding.
