Well yes they are more efficient than butyl for drag and weight, it's just a very small amount that would be hard to detect. And it's only for acceleration that rotational weight counts extra - up to double at the tire edge. Climbing at constant speed it is just simple weight.

And if course on the flat at constant speed weight is irrelevant, which is why a few kg of weight has a small effect on times, and 100-300g less tube weight is barely measurable, being a fraction of one percent better some of the time.

I don't think so. I think they're better but it's a very small percentage in terms of times. Close to latex IIRC.

I do believe there is a solid benefit in comfort compared to typical butyl with supple tires but that's pretty subjective.

The only downside in my mind is they're slightly loud. I'm very happy with them, and recently had a puncture and was happy that the patch seems to hold.

There are lots of cyclists in the photos. We're you expecting them to all crowd together in one spot?

I wasn't trying to give you advice, I was describing the situation in general. 🤷

It's very hardware dependent with a few problem's like Nvidia. For Best results go established brands that support Linux like thinkpads.

Steak fries are not shown here. They're bigger again.

Dynamic typing is shit. But type annotation plus CI checkers can give you the same benefits in most cases.

Once you need performance

If you need more performance. Many things just don't.

The post didn't mention Hollywood or a profit motivation.

That's ironic. Few countries have less readable plates.

Excellent description of the zeitgeist.

Your portrait of before generative AI is a bit hard to square with the ad driven internet, but fits ever better the further back you go.

Yeah, we're turning it all to shit in so many ways simultaneously, it's truly something awful to behold. Maybe there is a singularity coming after all, but it's not one like the credulous tech worshippers imagined.

 

This is my rescued Marin Hamilton, that over the years has evolved into a modern take on the old English 3-speed. My former commuter was stolen, and at the same time this appeared, broken, rusty, and abandoned on the same office bike rack (coincidence?). I saved it before the office management sent it to the trash, and got it on the road again.

The wheel bearing races were pitted from rusty neglect and I find SS awkward in the urban stop-start, so after a failed experiment with an SRAM Automatix 2-speed hub I fitted a Sturmey Archer 3 speed. 3rd is a single-speed ratio, 1 & 2 are for hills and setting off. It's a sweet setup for my area and usage, and is almost as robust and low maintenance as SS.

A transportation bike needs fenders (Velo Orange Zeppelins - excellent, effective, silent). The original fork rang like a tuning fork on braking no matter what brakes or pads, so I got a $40 Marin fork off Ebay and converted the front to disk, and put on generator lighting at the same time.

And just now it got some luxury new tires - Schwalbe Marathon Supreme 700x50 on the label, but are actually 43mm, in typical Schwalbe fashion. Great tires though - light and fast and grippy and durable and puncture resistant.

It's a fast and comfortable city bomber. I have a little TSDZ2 motor and battery that I fit each year for commuting the hottest summer months, and then in winter it gets studs to get me through the ice and slush. For fairer weather riding I have a very similar derailleur bike and the pair of them get me around nicely.

 

In Cambridge, MA, USA, and nearby communities, bike advocates have made real progress with lanes and paths and general infrastructure. Also the city requires that new builds have a proper bike room. This building was recently gutted and fitted out and this is the bike room today - overloaded, and the building is barely half full... Looks like they will need to find more efficient bike racks!

Meanwhile in a recent commute I was in a queue of 30 bicycles at a light at which about 6-8 cars get through at a time. 10-15 years ago I was one of the few bikes on the roads at any time.

Hats off to the advocates and representatives of the local cities that have made this happen through continuous pressure and work over decades...

 

The lack of keyboard interface on Lemmy is killing me, but really what I want is a good client in Emacs. However, it's beyond my Elisp to design and start such a project, but I could probably help. Anyone on it?
