If FEMA had the bicycles, would it fund Hustler's manlet bib?

Poverty wheels on my poverty bike.
The wheels definitely feel like they roll smoother and more circular, if that makes sense. The substantial difference is in grip and cornering confidence. The bike feels more rigid when I lean in and I'm more comfortable hauling *** in corners. There is a huge difference between this wheel and the Aksium Race in rolling resistance. The feel like they roll and soak-up bumps the same way the Ksyrium Elite wheel did, but this wheel feels like it's way way way better in corners. It really felt like a different bike.
I rode them at 110psi, people say to go as low as 85psi. Thoughts on this?

I'm going to drop to 100 rear, 95 front. Supposedly wider wheels can run lower pressures with no increase in drag. This is a 23mm wide wheel from bead to bead so supposedly I can drop pressure for comfort and get more grip. Not sure if that is hype or not, I guess I need to give it a try and use the pyrometer.

damn- those are WIDE for road wheels... most MTB's are about that wide (internal width- right?)
All that sounds about right from my experiences with wide MTB rims (lower pressure on wide rim=same rolling resistance and more grip).

Yes, 25mm width at the oustides of the brake tracks. The outside profile of the wheel is wider than the tire for aero purposes. I just took it out for 20 miles to see how it road and two dudes asked me about the wheels, one seemed to think they were MTB wheels, lol.

There is some evidence that lower psi will REDUCE rolling resistance, which is not intuitive. I dunno, being fairly heavy for a roadie, I don't like how tires feel below 100psi.
About ti bikes: they are a little bit granola, but the ride is super smooth. Maybe even on the soft side for racing. Looks nice though.
Aint nuttin wrong with alu frame as long as it fits you. If you want to go faster, you will get way more return by training more/ better. Pantani went pretty fast with alu frames. Always feels better to inflict pain while riding a bike lesser than your opponents. Very satisfying.

These will give you even more traction. Plus they'll push the air around the bike. You'll have to calculate whether the extra rotating mass vs the aero benefit. Either way riding Paris Robaux will never be smoother with these bad boys.

So, by wheels, are we literally talking about wheels? As in, the round things whose primary function is to sit between the tires and the frame?
I have to ask- what the heck are a set of wheels doing that's so amazing?
Sidebar:
Since I moved up here to NYC, the e-bike has been shifted from daily-driver status to occasional heavy-haul vehicle on weekends. A $98 Walmart bike (in the Jersey side) and the Citibike system (on the Manhattan side) are my primary rides at the moment.
Took the e-bike out yesterday for a big grocery run- first time in about two weeks I'd ridden it. Observations:
1: Oh, yeah. This baby sure is fast.
2: Hot damn, I'd forgotten how heavy this sucker was!
(I mean, it's not THAT heavy in the grand scheme of things, but compared to a poverty bike, it's got some heft to it...)

Remember is school when they had you hold a bike wheel In front of you're self not spinning. How easy it was to move around. Then the teacher spun it and those same movements were resistive. The lighter a wheel and particularly the outer edge of the wheel (tire, tube, rim nippes) the easier the bike accelerates, brakes and changes direction. Then depeding on materials used there's different shock absorption and road feel. Wheels can be built for different surfaces and rider weights.
Good wheels can change the feel of a bike more than any other parts on the bike. Rotating weight is a critical thing for the under 1hp crowd (humans)

I think there are two major differences in these wheels compared to the Mavic Ksyriums which weight the same, aside from bearings. The Flos use a steel spoke. I hear that these spokes behave difference, but I don't know first hand. The rim shape is way different and I suspect the rounder, wider, deeper shape is stiffer.

Wheels make the largest difference to bike feel and performance. I dunno how the ROL's distribute the weight, but it may be the rotational inertia is lower versus the Mavics?
Sometimes how wheels feel and objective performance do not align. One my favorite feeling wheels were the old first gen Rolfs, and similar designed shimano wheels. There were heavy and slow in performance testing. I raced zipp 404's because they were supposed to be the fastest by objective measure, but I never really liked the feel of these wheels too much.
I had super light climbing tubulars that were awesome for seated uphill climbing, but felt terrible standing (especially the rear) and downright scary downhill. I only used them in uphill TT's.
hustler, you should do some "strava testing" on your old versus new wheels. Although not truely scientific, you will have kind of objective testing. For example, I found 88mm carbon rims about 5 secs slower than 50mm wheels up a 2km 8% climb. It was a pretty consistent finding with about 5 rides on each wheel set. The 88mm wheels feel like anchors when climbing, but only about seconds or about 1% slower climbing.
