Two others that I can think of are the Polar cadence sensor for the S510 and S710/S720 and the new Mavic computer. (http://www.mavic.com/...lg=uk&news.id=70).

I've got the V100 on my tri-bike and the V100A, which adds an altimeter, on my road bike. By far the best computer I have ever owned. So many features! I'm addicted to the altimeter on my road bike. It's awesome knowing exactly how many feet you've climbed, the %grade, etc...

If you're using Shimano STI (ie, not bar-ends) the wireless Flitedeck has cadence. It does it without a sensor on your cranks by calculating cadence from speed and gear ratio. Accurate, and very handy to have.

Also provides the nifty information of what cadence you would be in if you were pedaling, but are actually coasting.

Julian - I wouldn't describe the "cadence" feature on Flitedeck as "accurate". At best its an approximation.

As you rightly point out, it doesn't take coasting into effect. Accordingly, to the extent that your speed is increased/decreased by external factors, you don't get an accurate reading. I'm not sure what value it has in those circumstances (other than as toy).

Neal, the cateye cd300dw also has wireless cadence.

I used to have the Vetta v100 and had a lot of problems w/ it. It seemed that either the cadence or the speedo was out all the time. It really sucked when the speedo would go out during a race (this happened a couple of times). I now have the Mavic Wintech puter and have had no problems. I really like that it sits on the stem between my aero armrests. It does get a lot of sweat on it here, but I have had no issues. Only about 1,000 miles w/ the mavic so...........

Yes

Gotta strongly disagree. Yes, you get a reading while coasting. But that number would be accurate if you were pedaling, and yes there are times when that info is a plus so you can drop into a gear that won't have you spun out if you were coasting down a descent and then started to pedal at the bottom.

The cadence reading is accurate as long as you have the correct cassette info set up on the computer. You can set up multiple bikes on the computer so you have the settings for different cassettes if necessary. The only other reason for cadence to be off is if you calibrated your computer for the wrong size tire. Then again, your speed would be off with any computer as well.

I've got both the flight deck and polar cadence and I pretty much get identical readings between the two units.

I just ordered the Cateye CD300DW from lickbike.com. $98. I will let you know how it works

The Polar cs200cad has wireless speed and cadence sensors.
