The shape of bikes to come
>>2075046>would be more useful to describe the tire as having (fewer/less in) losses, not "being fasterYou're just arguing about semantics which is retarded>you'll notice that this sort of language almost never appears in marketing for tires for any other sort of vehicleFuel efficient tiresYou're so convinced you're smart but you're actually a fucking dimwit.
>>2074857If your bike doesn't look like this you're poor
>>2075393Yawn
>>2074902traction is simply the static friction between your tire and the ground times the normal forcerolling resistance is energy loss during tire shape restoration as it is deloadedthey are not necessarily the same thinga train has fuck all rolling resistance and literally tons of traction
>>2075051NO!!! DO NOT DO THIS> YOU HAVE TO RUN TUBELESS FOR LOWER PRESSURE
30 years after Mavic Zap, I finally tried three different bikes with electronic shifting (Rival, Force, and Red/XPLR) and it reminded me of the first time I got my dick sucked. It was alright. I'm glad I experienced it. But the overall feeling was like.... "that's all? that's what all the hype was about?"I am glad it's a thing, I'm glad it's available, I would never tell them to un-invent it. I suppose if you offered to upgrade my current bikes with all electronic I'd probably go for it (might have to think it through first). Overall, it was a disappointment.So what did I miss here? Is Shimano better or Campy maybe, was the problem fookin SRAM? Is it less about the ride and more the long term ownership experience, the maintenance perhaps? Why do people fork out 2-3x the monies over the cost of perfectly good mech shifting? I can't believe I'm even saying "perfectly good (old thing)". I love my hydro dicks, I love my crabon wheels, I would never go back and those were worth every penny, but the e-shifting was a big letdown. Again, it was fine, but just fine. For all the hype I expected to ejaculate instantly.
options for shifting over WiFi 802.11AX?
>>2075327It is literally impossible to shift under load.
>>2075336All shifters will be required under NY state law to have an always-on internet connection (BLE using the same network as Apple's Find My) that checks your shifting in real time to make sure you're not on the way to or from a shop that sells objects that could conceivably be used as manufacturing precursors to a ghost gun, such as objects made of plastic, wood, or metal

hi /n/I am enrolling the Galveston maritime academy this Fall. By the time I graduate in four years what do you guys predict the American Merchant Marine will appear like? I was told that engineer officers have good job prospects by the colleges and by some Mariners I know. But I also hear that getting a job at MSC is a bitch and that union jobs are drying up? Is the job scarcity mostly on the unlicensed side or even officers will suffer. btw any Galveston alumni pls tell me how bad the Corp of Cadets is
Go for it, in hindsight I wish I had done that when I was younger (Mass or Maine Maritime Academy). Plus it's getting a new training ship this year so at least you'll be learning on modern equipment vs some old steam rust bucket. The gov't is finally realizing it wasn't a good idea to cede shipbuilding to China so hopefully there will be a renewed emphasis (eg money). Good luck to you
I watch What's Going On With Shipping and I've been on a fishing ship for half a day once so I'm an expert on this subject. AMA
I don't watch any youtube channels related to shipping or maritime transport but I took my uncles boat out onto the ocean about 15 miles from shore so I'm an expert on this subject. AMA

>>2070451Worth riding rough to never have the state make excuses to tax.
A few years ago people starting referring to certain China wheelsets as not just "the best Chinese wheels" or "the best budget wheels" but simply "the best wheels". This year, Winspace released the T1600, a CDM (Chinese Domestic Market) product that costs more than a Madone or a Tarmac. It's UCI approved right out of the box (though you may need to tape some lead weights to it to get it to pass the weight restrictions). Western buyers need not apply, though they no doubt will try.Western brands were folding right and left before the iron curtain 2.0 was raised, now the "tiro de gracia" has been fired and big companies like Trek are going to go bankrupt because their supply chains have been cut off by Import Substitution Industrialization, a popular third world development tactic pioneered by visionaries like Pinochet and Galtieri.Is this the end of the western bike era? Will tomorrow's dentists settle for nothing less than Chinese bikes on 100% Chinese groupsets?
>>2071484Of course they work in the rain, just like non antilock brakes work in the snow, but strangely everyone seems to agree that "works better" is a compelling reason to buy something over something else.
Why did bikes take so long to het disk brakes? Cars have had them for a long time. Clamping onto the rim of the wheel to stop is the dumbest shit imaginable.
>>2071488The amount of clamping power you need to break effectively with good modulation on 140mm dicks is astronomical compared to the amount of clamping power you need on the outer rim of a 700c wheel. So hydraulic is really the only way to go, and the bike industry was coasting on cable break inertia. Hydraulic breaks came out for mountain bikes a long time ago, but that is a simpler system to switch over, because the breaks are their own separate thing. A road bike has a combined breaking/shifting assembly. So you have to switch essentially all of the most expensive and complex parts of the bike. And that costs money to finance that initial jump, which is why the first systems were exclusive pro-tier setups.The other thing that accelerated the push was the expanded availability of carbon fiber parts. With carbon becoming more affordable it was possible to make wide, stable, gentle-riding, grippy, stiff, aerodynamically efficient wheels without a major weight or cost compromise. But this rendered most of the unc break designs incompatible with the build. Since a new set of breaks was going to be needed anyway, suddenly it made sense to put dicks on everything.
>>2071488It's because mech dicks don't actually work. You don't get enough braking force, there is no modulation, and all you're doing is making your bike less safe because if anything fails now you have a razor-sharp brake rotor flying at you at 900mph. Cars only have them because cagies aren't real engineers and believe anything big auto tells them about what's best. Cars have them simply because mech dicks are cheap to import from china. That is the only reason.
>>2071488>Clamping onto the rim of the wheel to stop is the dumbest shit imaginable.Then why do the pros use it?

>built a dozen wheels>always do the ali clarkson method of relieving tension aka "toss it on the ground and walk on the spokes" after first pass truing, to then re-true again>new wheel build, new wheel walk>it tacos and breaks at the seam, rim's fuckedwell shit, apparently stuff i've been building so far has been extra sturdy because that's never been a problem for me before. how do i do it without it then? italian tuneup, just 200 km and re-true? i ain't buying a tensionometer, they are for dorks.
>>2075561the only way I was shown was to squeeze them together as hard as possible as you work around building tension while on the stand, and also periodically put the hub on the floor and press your weight equally on the diameter of the rim and press, turn, press all the way around. repeat several times while bringing up the wheel tension. sort of similar to walking on it I guess (which I've never heard of, not that that means anything) but much more controlled.
>>2075543Bigger groups tend to grade their rides for different experience levels. Group ride culture is going to be the biggest filter. Signaling, observing signals, being able to respond to obstacles in a safe manner. Just being able to not be a danger to others (or yourself) will take some practice and you don't want to be trying to learn that stuff while you're also struggling to keep up.You may not struggle to keep up, or you might even if you are "fit". Roadie conditioning doesn't look the same as solo pleasure ride conditioning. That's why you'll see guys with a beer gut in those group rides. You can have good endurance and not be "healthy" per se, just like you can see guys at the gym who lift heavy weights even though their body looks like shit.
>>2075576oh, and flip the wheel to press against the other end of the hub on the other side each time, in case that wasn't obvious.

I flew down to the Bay Area to take a journey on the Niles Canyon Railway's mysterious and rarely traveled Eastern branch aboard the M200 Railbus. The last of its kind still operating, the M200 once served the California Western Railroad as a literal schoolbus for children. Today is its first publicly available excursion in several years.
think of this as an express flexi-bus
And of course back to the railbus
I’ve always wanted to live the mid-20th Century experience of riding a Pullman Sleeper hauled by a steam locomotive roaring through the night and while I have been fortunate enough to ride steam excursions many times and even do an overnight ride on an original Pullman car, I’ve never been able to do them together.Is there anywhere in the world where I can actually still take an overnight train hauled by a steam locomotive? The closest I’m aware of is the modern Orient Express being steam-hauled through Hungary as a one-time thing in 2017 and the Cumbres and Toltec possessing a restored tourist sleeper coach (idk if it’s ever been used in that role).
>>2068932>bl00dyWhy?
>>2068933Having a mishmash of non-matching rolling stock isn't exactly a pretty sight. SP 4449 and N&W 611 used to haul their original coaches and looked better for it but the consists have been broken up and dispersed to different owners since the 90s.Kinda sad if you ask me. I'd love to see 4449 in particular pull a recreation of the original Coast Daylight route from Los Angeles to San Francisco using its original cars (or at least ones that have been appropriately repainted to match it).
>>2068027>there arent coaling stations everywhereUP 4014, SP 4449, and N&W 611 have all successfully gotten around this by using additional tenders/conversion to oil-firing (coal was already going out of style when they were built).
>>2067924Steamy, dreamy... creamy?
>>2067924Long story short: insurance kikes and bean counter kikes.
Keep in mind this is for bikes meant to be loaded up. I guess a marketing exec at some point decided kickstands are for poors so no expensive bike can have them now, just like MTBs got stuck with Presta valves. They will literally drill 15+ holes just in case your bike bags use bottle bosses instead of straps, but outright refuse drilling 2 for a kickstand
>>2066365>bike falls over onto the hard concreteThe bitch was strong, the kids was gone, something was wrong, I said what was going on?
>>2074675I'm too young for you, miss
>>2064947i bought a "dutch bike" in a pinch and it had one of those. it was complete dogshit and even had a "feature" where you couldn't remove the fucking key while it's open. so you can't put that shit on your keyring, and if you get a karabiner or something you have to worry about it dangling and getting caught on shit. I know it won't but i don't need that kind of stress wondering if the lock was just sticky or if it'll break one day and the key will fly away during a ride one day later. i took that shit right off after getting it home from my first ride when i got it. i inspected it and it wasnt even a good lock, the shank on it is fucking tiny. also using it just during that ride a couple times it got fucking caught on the spokes every goddamn time and you can't see in there to even sight if you're clearing the shit. awful fucking system. just carry a normal fucking cable or u lock.

> Fargo 32 is for riders seeking a drop-bar mountain bike with the new 32er wheel diameter. Available in the fall of 2026, in either a steel or titanium chassis, the Fargo 32 maintains its Salsa DNA with an abundance of cargo mounts, an off-road touring tuned geometry, and clearance for 32 x 2.4″ tires.It's. Happening.
>>2072390That wasn't the point. The point was that they are not as much of an improvement over older standards than the proponents of hydros would lead you to believe they are. Also that 180 dollars could have been spent on 18 innertubes, which have a real world benefit that is immediate and not marginal like 70cm braking distance.
>>2072155Your feet only need to reach just past the axle for pedalling. You could theoretically have 60" wheels if you wanted.
>>2070774cool >32" tires>wtb horizons with shitty puncture protection and feels like biking though dry sand
If huge wheels are good and fixed gear is best, why aren't we still riding Penny Farthings?

I want to strangle every single big buck roadie fred and especially every single downhill-bike-in-a-park pomp who rides around just to do chainsaw sounds with their bicycle's very very expensive hub. "Give way, the asshole is coming!". Like, if you wanna make motorcycle sounds, get an actual motorcycle. A Harley actually sounds cool. A freewheeling bicycle sounds supremely annoying, and also means you are a weak shit who is not pedalling. Fuck you, go ride into a river.

>>2068223>front engine rear wheel drivethe bike industry is full of wrenchlets who dont even ride
>>2068223the main reason THEY dont do this is that it counts as a motorcycle in north america, most of yurop, and industrialized east asia, so at that point just get a proper motorcycle or sit-down scooter. actual mopeds (as in purpose built motorized pedal bikes) are still popular in southeast (tropical) asia and russiaalso the two stroke died because it doesnt pass emissions regulations, and four-strokes are just physically too large to put in a normal bike frame. also four strokes arent useful below a certain displacement (150ish cc and smaller they just arent worth compared to a big 2-stroke) so again may as well just make it a shitty baja bike, but at that point it is essentially a motorcycle and the pedals are vestigial, so may as well stop pretending and just design and sell it as a 200-250cc motorcycle even in markets that would have allowed small displacement 2 stroke mopeds since at that size it's either it's a 4-stroke that is too small to justify its complex structure or a 2-stroke that is too big to comfortably go on a push bike anymore

Mexican railways thread? The government of Mexico is trying to bring back long distance passenger routes and building light rail in the Mexico City metropolitan areaRailway history in Mexico is actually very interesting. They used to have a national railway company called FNM after they nationalized all the railroad companies in 1908, until the 1990s when they privatized it. >Isthmus of Tehuantepec railway - three lines >Buenavista to AIFA airport to Pachuca intercity railway>Texcoco to La Paz light rail >Costeno, Jarocho route revival>Mayan Train

They never even finished the line from Cuautla to Chilpancingo and then to Acapulco...
>>2064673They can get away with tren maya because the only people living in that area are click language prehispanics with no political power, so they can just lay down a ROW through people's ancestral home and who's going to stop them? The rain god?
