If your primary goal is minimizing work, you can also try an electric bike, or driving! Tongue in cheek, but isn’t fitness the point?
Same fitness on a more efficient bike = longer distance or higher speed.

Literally 5 seconds of investigation revealed that they offer three durations of membership, each a one off payment (the per month pricing is just a representative amortisation). This is actually so easy to discover, and so easy to understand, that I'm guessing you're just reflexively enraged.
Continuing membership requires recurring payment not "one-time payment".

I've switched to Schwalbe Marathon Almotion from some knobby Kenda and they made a night and day difference. It was a pleasure to ride in the city.
What type of difference did you notice? I switched from a stock Bontrager tires to Continental Grand Prix which are supposed to be high end and didn’t really notice too much of a difference.

No. Wheels are a prestressed linear superposition of overall tension and a compressive load at the bottom. Generally, you'll see ~4 spokes at the bottom of the wheel relaxing to take the vertical load. (in a properly built wheel) This is due to rims not being completely rigid, but being a somewhat flexible beam. Rims are nowhere near rigid enough to do the "hang from the top" thing. Spokes will break at the elbow, bu…
The compressive load is negligible, that's why you can build a wheel entirely out of non-rigid spokes such as liteweight wheels or https://berdspokes.com/
You wouldn't want berd spokes to go slack any more than you'd want steel spokes to go slack.

Unfortunately you cannot discount the “sponsor effect” here. Wheel manufacturers have been pushing wider rims because it helps them sell another set of wheels to everyone. In the days of rim brakes a wheel had a finite life (the length of time it took to wear down the braking surface). Then shimano and the frame builders pushed everyone to disc brakes, so the wheels now last for ever. What do you know, 2 years later…
I think you might be transposing the cause and effect. Mechanical rim brakes had been limiting the wheel width because of physics of leverage, disc brakes opened demand for wheels of any width and users naturally migrated to the wider wheels.
It's always: this is the latest model, it has these features, thanks.

> Wheel manufacturers have been pushing wider rims because it helps them sell another set of wheels to everyone. I think the push to wider tires and lower pressures on road setups is actually because hookless carbon rims are much easier to manufacture than clinchers, and hookless tires can't handle 80+ psi. Clincher carbon wheels are basically considered a niche product by big manufacturers

You're kidding yourself if you think Pogacar would run 30mm tires at 55 PSI at the detriment of speed to please his sponsors. Cyclists are notorious for re-badging stuff they don't want to use and being super finicky with their gear. You're talking about guys that hardly celebrate a win with a $250k purse because they want to make sure they stopped their ride right on the finish line on their headunit.
If you look at TT equipment all team members use the same helmet regardless of the fact that helmet performance varies massively from rider to rider.
The 2016 S-works Venge is 5w faster than both the SL7 and SL8, so on flat stages all specialized sponsored teams are riding it... aren't they?
Why is nobody wearing a TT Helmet and visor on a normal road stage?

I feel that any marketing strategy that relies on the niche of a niche formed of the people that would buy the cutting edge cycling gear just because it's presented as an improvement over the status quo, would hardly bring any benefits to any wheel maker. I am 100% sure that in this age of "marginal gains", the pro tour teams would not go for anything that doesn't give them it unless severely hamstrung by sponsorship…
My experience is personal, but I get 50,000km out of a set of rim brake carbon wheels ridden in all terrains and conditions and through northern european winters. At that point you're also starting to lose spokes/nipples to corrosion, but the rim could be rebuilt with new spokes and a new hub if it didn't need a brake track. That riding includes racing, crashing, potholes, punctures.
Pogacar rides on Enve wheels, which are now hookless and therefore a puncture is much more likely to result in damage. Another innovation that makes life worse for the consumer and better for the manufacturer.

To add to this, unless you are actually competitively cycling (you probably aren't) this sort of thing makes pretty much no difference for someone that is using cycling for transport. It's a bit like obsessing over the lightest frame possible. Yeah, we can get a 1lb frame made of space materials but at the end of the day it's basically something that will reduce a cyclist's average speed by like 0.1mph. For anyone do…
I think it’s a little different than bike weight, which makes very little difference for anything other than lifting it onto a rack or taking it up apartment stairs. Rolling resistance makes slightly more difference than that.
