Being able to freely change wheels is and always will be a serious advantage of non-wheel based power meters.
Overwhelming in all situations? No. Look back, I haven't said anything of the sort. All I've been saying is that it is an advantage. And since the majority of power users will at some point want to swap wheels around, I think it is fair to call it a serious one.
Wait, I do dispute something: whether a pedal system was available or not when somebody bought their PT doesn't preclude the pedal system from having certain advantages. Likewise for said pedal system being out of someone's budget. It still can have certain advantages.
It's price is a serious advantage over the other proven systems. Does that mean everyone who bought a SRM was wrong? No. There are other serious advantages to that system as well.
Your arguments only make sense if one of us is saying that either the PT or all the non-wheel based PMs have ALL the advantages. I'm not and have never said that. Are you?
So you take em off for races much like some people take off training wheels and slap on race sets for races.
Sitting here with a pair in my lap, have to say, very very nice.
I think Garmin's going to face some uber-stiff competition from the Stages ($800) powermeter given their $1700 price point. Sure, it's probably similar to Quarq in price, but still very, very pricey. Ive been very happy with my powertap wheel that was about half that.
Campy and quarq work fine together. Quarq just doesn't have a campy crank
