Bike weight and fighting wind
Theoretical question on riding into the wind on a heavier bike vs a lighter bike. I know heavier uphill is more work and less efficient. I have seen it speculated that once one gets the weight going, it doesn’t matter, but does it? I get more of a workout with my kitted up miyata 1000 than I do on my lighter sport touring bikes. 2 mph ave speed difference is usual.
Lots of variables I know, including 35mm paselas on the touring bike but I was questioning if that was that big a difference. It just seemed to me that it would take more work to keep the 5-7 pound heavier bike cutting through the wind. Am I wrong here.

Adding weight won't help you ride faster into the wind, nor will it make it harder. The physics between the two aren't coupled.
Getting into a more aerodynamic position will. About the only time I move my hands down into the drops anymore is to fight a stiff headwind.

And you're probably not maintaining a constant speed, so there will be accelerations throughout the ride, which will slow you down.
Weight is not a factor in wind resistance.

Noticing how 'modern' bike setups place bars much higher versus saddles than I am used to, that seems comfortable but once in the drops, perhaps not all that low and there's nowhere left to go. Perhaps a future development might be bars with a second set of drops below the first.

If you have bags on the Miyata that will be the most problematic into a headwind. I love panniers until I'm riding into the wind.

Same here.

32s on my other bikes mostly, so not a great difference. The Miyata has a soft “trunk” bag on the rear rack and a small one on a front rack so obviously not aerodynamic. I do like the explanation about slowing down and speeding up causing losses. Even with those explanations I would still bet the added weight is a factor. Take a car that weighs X and gets a certain mpg. Wouldn’t it still take a bit more power to propel with 500 extra pounds in the trunk and everything else is equal?

I think it’s ALL about wind age and ride position. Yes, tire size can be a factor. My favorite bike for a headwind ( yea I hate head winds too) is my Medici. It has 700 x 25’s and the stem is lower , for some reason it just feels right, also the frame is a 60 when I normally ride a 63. I ride the “tops” more on this for obvious reasons ,but the drops are great down low for an aggressive position when battling a headwind.
For some reason this feels right for this bike . With aero brakes I can ride more easily on the top and drop for wind or any aggressive riding

I think the only thing I learned in my science class is that wind doesn't blow, it sucks.
I mentioned that in class, I think, got Zero credit for creativity. And detention.

I ride a Monday Night Shootout that 95% of the time, is with the wind going out, comes back directly into a stiff headwind.
It seems worse this year, so much so that many are opting out of the ride.
I'm fortunate that I can ride various bikes on this ride, so I do.
The wide-body carbons with deep V wheels seem like a handful.
The steel C&V with box section rims don't seem quite so bad.
Funny, I'm still a bit faster on the "handful," for most rides.
Perhaps 30 years of technology does actually make a difference.
I still like the steel bikes better. Just more satisfying to some instinct.

Riding into a headwind is just cranking up the need for best aero.
these mod bike guys around here seem to have 35-50mm deep front rims and 50-80 rear.
makes sense. All carbon, carbon, carbon...
they spend big for the privilege.
