I just ordered the Wahoo Fisica mount today. It includes an ANT+ radio that lets your iPhone talk to a speed/cadence sensor, heart rate monitor, power meter, etc.

Their sensor case is still listed as a pre-order, but I put in the order this morning and got a shipping notification a few hours later.

I'll try to remember to check back in to this thread with my impressions after I get it in and set it up.

One thing that really sold me on it was their Youtube video (http://www.youtube.com/watch?v=GySix...layer_embedded). Looks like a solid case with a good mounting system as well as good waterproofing. We'll see, I suppose.

I was hoping to get the Pedal Brain system but their website hasn't been update in months, so I suspect that one is vaporware.
