At $1700 its WAY Overpriced. I agree with Merlin, swapping a Quarq is seriously a 5minute job. I've swapped mine between my road bikes a few times and its SUPER PAINLESS!
I really don't like how this locks you into the LOOK based pedal system. It's not like locking you into a crankset is a big freaking deal, especially with the newer Quarqs that will automatically recalibrate to different chainrings.
Swapping pedals is a 5minute job too but for some reason people think that swapping a crank is rocket science(lol).
$1700 is overpriced for beta testing.
independent pedal power? Thats super useless. I've been training with power for about 8 months now and have zero interest in looking at power from each leg, and studies have shown that if you try to balance it out you just decrease the power from your more powerful leg(as if it all matters anyways).
The difference is 2% which is pretty much p[ointless to talk about in terms of power reading.
