DA Power meter and?....

Looked at the article, interesting but what's MOST interesting is at the bottom of the article, the ad from ProBikeKit..discounting the thing BikeRadar just tested.

Good marketing.

That's online advertising. Pixels fired fast!

I was waiting for this as my nine year old Quarq started to throw up some odd calibration numbers but a) I got tired of waiting, and b) I had a vague concern over the first version of a pm. I know Shimano is different from a startup and they seem to be using a Pioneer style approach, but so many companies seem to have trouble getting a reliable product. So, I took advantage of Quarq's generous out of warranty replacement and got a Dfour 91 a few days ago.

That plug scares me. It seems like it would be easily torn off.
