Does rotating weight really matter?

What I want to know is if rotating mass makes a difference on bikes hanging from trunk racks with one wheel spinning while the car speeds down the highway. Do micro-accelerations affect gas mileage?

The spinning added mass is what causes the handlebars to spin around a put a scratch in your paint.

I have seen ads which tout the reduction in rotating weight as a significant advantage. Any search I've done says this is a myth or, at best, there is a minimal advantage in specific situations. IMO this does not justify a large expenditure of money. Especially when I could, and should, lose 10 lbs.

Pizzas kinda look like wheelsets. You can get a pizza delivered to your house by the pizza maker. The wheel companies use a third party for shipping however, and it usually cost you a fee to get them there. That's the only spin I can put on it. That and don't spin the pizza or you could lose the mass off of it.

The plot thickens...

I went back and had a look, and you're right it's your third post I was responding to not your first one. Nonetheless, people are allowed to have wheels they like even if you want to lose ten pounds, and I still don't see the connection there. I can see the bit about "willing to be convinced otherwise" was pulling our legs though.

But I can tell that you have never ridden or jumped a bmx bike vs a downhill bike either.. Bmx bike spins and gyrates differently compared to the downhill bike, and it not just because of bike size either. Rotating weight. Forget bmx, just take a road bike and put some 50mm deep wheels and sprint, now do it with 80mm wheels. Tell me if you don't sprint quicker in the 50mm. Climbing is just a series of mini accleration. Does it matter now? up to the rider to judge, but if rider cares about performance, then it matters.

Rest assured if one rider has 3.5 w/kg and another has 3 w/kg it won't matter who has the lighter wheels 3.5 w/kg will be faster. If both riders had the same w/kg saying the rider with lighter wheels would be noticeably faster is doubtful at best.
