I took a tumble and bent the left side of my shift housing. It's almost imperceptible but given it's my bike I noticed it off the bat.

I'm assuming there's an easy fix, but it isn't apparent to me. Can someone take pity on me and help me out?

It is my first time posting on this board, as I come to you for interesting and productive discussions.

Are there any Ukrainian anons on this board? What do you think about the current situation with transport and infrastructure? What do you wish was to be implemented / removed, that already exists in West or East? What do you think of Pic related?

Oh no anon, that is no bus. That's "мapшpyтнe тaкci", which would be approximately translated as "taxi on line". It is technically a microbus, that has something like 20 sitting places plus as many standing. Their purpose is technically identical to regular bus, but they are cheaper, so we have more of them. Also, their size allows them to pass tighter spots and more extreme slopes, which are rather common in my city.
Very nice, thank you for your interesting point

No Ukrainian here, but from a tourist perspective arriving in Kiev by train and riding around with the Metro and the Marshrutki (is that the Ukrainian plural? I only know some Russian) was comfy as fuck.

Obviously everything is a little run down and many systems only continue to exist because soviet technology was built to last, but it makes me happy to see how good of a transport system can be held up with so little, especially looking at Marshrutki. Also why are the Trolleybuses so slow? Bad shape of the catenary?

Also it appears that you can get by without a car in most larger cities (well, many people just have to), also there is a network of night trains connecting the country.

I know you can frame it the other way aswell: Night trains are only there be because the bad Infrastructure enforces low speeds, even suburban trains only run a handful times a day, UZ is being eaten up by corruption, there is little money for improvements, Kiev Metro has capacity issues during peak hours I haven‘t even seen in Tokyo and and and...

But from a transit nerds perspective Ukraine has a lot of potential and is probably already better than most countries worldwide, overhaul the existing tram and Trolleybus networks for higher speeds, add some live departure information to the Marshrutki and then you‘ll have some really decent transit.
>overhaul the existing tram and Trolleybus networks for higher speeds
Not possible without massive investments into road and tram rail quality. Also, trolleybuses can't go faster, as dedicated lanes are often packed with parked cars.
>add some live departure information to the Marshrutki
It was done a few years back where I lived, but it didn't really work out because they never were on time and they turned it of.

I'm a great proponent of metro expansion, as I absolutely love it. Also Kyiv has extreme parking problems, making it 12th most congested city on a planet.

P.S. Pickpocketer stole my wallet in marshrutka today, with my passport and driving licence inside. That was fucking disappointing, desu

Why have multi level cities yet to catch on despite the immense value they'd provide?

I'm guessing it's because 4 year term city governments don't want to commit to such a comprehensive rethink of cities.

powermeter talk,

what do you guys think of the magene P325 ?
theresa kickstarter for it, 299 for a shipped dual side+chainring PM, really tempted on buying it, (cant link here cause it thinks its spam, but just google megane p325 kickstarter) .

shall i go for it?

If you're interested in chink powermeters Sigeyi is the choice. Other cheap ones are left side only crank arms.
if it's any good at all SRAM will buy them out like they did everyone else so what would it even matter?
the Magene seems really poorly made from a manufacturing standpoint, just look at that massive flex and the fucked up pedal holes and it had plenty of bad power readings in short tests. Seems like garbage to be honest.

Also from what I can see the chainrings and cranks are machined in one piece so once the chainrings wear out you have to throw the whole powermeter away. And judging from the crankarms that flex like noodles I highly doubt the chainrings are going to last 50k km.
There are very good powermeter options available at the 500-600 USD or Euro pricepoint like Quarq and power2max. Well made and very long lasting, don't cheap out on a powermeter that you'll use for many years. Don't put up with something that gives you faulty readings, get something good or you'll regret it.

>who puts a fucking nuclear reactor inside a bus
They did
That's not the use case. Imagine if they were around for ferrying people between the terminal and the far apart boarding places usually reserved for economy flights or GA. If they had a bus there, not even economy classes would suck that much, and also you have space for cargo underneath the deck, so you can carry and load cargo with passengers.

Also to reduce operating costs and seething by Greta, these could be made in electric for the ~ 1-2 mile trips they are expected to take.
He argues that cars and buses have no reason to live in the 21st century. I'd vouch for trucks, though, they're great in a local last-mile distribution, especially in electric versions.
> But what about articulated double decker buses?
For that amount of passengers, just build a tramway or a train if long distance

Then, for low to mid-volumes of traffic, you build a roundabout. For large traffic flows, you build a gigantic ugly blot-out-the-sun-forevermore free-flowing stack interchange.
>No lane mathematics

Why even bother?
Toll roads yay.
Any four-way interchange can be converted to a pair of three-way interchange. They are pragmatic under land constraint.
>lane mathematics
This meme is fucking annoying. It's called "lane balance" and basic number of lanes if anyone is remotely concerned about it.

California is wasted on the californians

Since I'm using my bicycle as an utility device, often I find myself running out of cargo capacity in my rear cargo bags. The loads I carry (~ 20 kg, anything larger I'm carrying by car) are also problematic.

I'm thinking about pic related as a solution, and as one less reason to use my car, especially with an electric version, that could make a 20 km/direction trip fully loaded (local farmer's market, currently that's done by car because of the expected heavy loads) without any difficulty.

Yeah, I'm not /fit/, so I probably can't cycle centuries.

Only problem is that even from aliexpress, it's fing $1k + duty, taxes and shipping. From yurop, the quotes I've heard are closer to €3k.

Also, I haven't seen a cargobike with 28" wheels, and being 6'3", that could be a problem.

Is this a good idea?
What alternatives are there lugging cargo around with a bicycle?
What non-car alternatives are there? Are electric scooters any good?
Also, cargobike general.

as above, no need for that - a touring bike fitted with a sturdy rear rack, good quality panniers, and a large basket on the front would be a much better choice for casual haulage. add a trailer to that and you can move pretty much anything.
touring bike since the geometry and overall construction is dictated by the need to carry a lot of stuff and still be easily rideable - you could likely do something that would work with an old mtb though.
no problem with cargo bikes but it'll be heavy and slow, quality will suck below a certain price point also. an electric assist would make sense but then you're looking at $$$ so...

lol, you need to get a fucking grip sonny
gotta love boomerposting lel
Trailers generally come with the necessary attachment things. Single wheel trailers usually have a fork type thing on a swivel that attaches to both ends of the rear axle, but ones with a high drawbar that attaches to a ball mount on the seat post exist. Two wheeled trailers either have the same high drawbar with seat post attachment, or a low drawbar that attaches to one side of your rear axle. Low drawbars nearly don't affect bike handling at all, but have a limited turning angle in one direction (usually right), high drawbars that attach to the seat post have a far greater turning angle in either direction but with heavy loads you can kind of feel them tugging on the bike when you lean into turns and they take a little getting used to.
Op here.
Actually I have looked for /n/ solutions to an /n/ problem, anf have found actually helpful posts like

Suggesting me a trailer and >>1576885 also suggesting s great rear hub, as my current rear hub is broken from the constant overload

Also a great idea was long johns, and a long bike upgrade kit (>>1576815) which would also allow me a path to disc brakes without having to buy a new frame.

Thank you all for the contribution!

the wider 140 mm hubs were common on touring bikes and tandems at one point
to reduce the dish of the spokes and keep the wheel from bending sideways so much
smaller wheels or larger hub flanges will also have the same effect

one wheel trailers have a more simple mount but tend to be a little unstable, some are cheep but likely only just sufficient for your 20 kg ish cargo
most trailers do put a bit more stress on the rear wheel so its something to keep an eye on
rear wheels are the weak part of most bikes
