Another Powermeter
 

The B&M PowerReport:

Price?
Also, I wonder if they make it in a non square taper design. That seems limited due to the fact that a lot of cranks use other attachments but I guess that's no different than a SRM where you buy the whole crank.

Here are a couple more:

Wow, it has "Heart rate control using 3 flashing LEDs". That's an advanced feature. Heart rate higher than you want it to be? No problem, just use the 3 flashing LEDs and bring it back under control! :D

I found this UK-based site which has it for £750. No info on whether it comes with anything besides a square-taper BB. It would be interesting to read some reviews, particularly from any of the PM gurus...

The micro sport can not be that accurate. It fits on your shoe? :eek: So much for one legged drills.

From the website...

How It Works:
Force sensing insole inside the shoe. How hard the cyclist pushes on the pedal is measured.
All cyclists apply pedal force and cause torque in the same pattern*
So: torque can be calculated from the measured force!
Angular velocity is calculated from the period of the force curve.
One sensor tells all!

One of the other high dollar power meters only measures one leg, I forget which one.

The ERGOMO and the PowerReport both use a BB sensor. They seem very much alike in that regard. Cockpit instrumentation and analysis software seems to be better for the ERGOMO. German companies make both PMs. I wonder if they're related somehow.

My Ergomo display is huge. I think it plays movies.
