Recently, China's domestically produced comac C919 passenger jet model has carried its 500 000th passenger. The first model was inducted last year, 9 models are now in service. This marks a significant milestone in China's commercial aviation industry.
did you know japan tried to build their own too but failed?
why china can build commercial jet but japanese can't?
look up mitsubishi spacejet
>development suspended
>As flight testing took longer than expected, the scheduled entry into service was further pushed back until development was first paused amid the impact of the COVID-19 pandemic on aviation[2] and subsequently suspended indefinitely.[3]

It has the same cons as almost all friction drives.

The only pro is it's easy to install, work on, and take off compard to chain or belt drives.

in a perfect world, wouldn't these be parasitic to the cassette? like with a secondary chain and its own dedicated chainring? (you wouldn't shift into it, you'd have to make some modifications so you don't accidentally shift into it)

Is there a reason why this isn't the norm? like it's so obvious and better than friction drive, just need a chain.. idk.

I didn't see one or something similar in the catalog so here we are and I need help.

I had my chain skipping in the hardest gears on my road bike, 10speed cassette and double crank, which I don't normally ride in. But no issues otherwise
So I thought maybe my chain was to blame but never measures and don't have the tools for that anyways. I bought a new chain and now it starts to skip on the front sprocket.
Now I'm starting to wonder if I have worn out both the front large sprocket and the middle of the cassette to the point I just need to replace all of it... thats a little pricey and I'm cheap.
How should I proceed in trouble shooting this?

thanks in advance

unless those tires are annoying you there's no real reason to replace them before you wear them out. when you do order more, getting the widest size that will fit between your brakes, fork and frame is the current wisdom. beyond that, it depends on how sporty vs utilitarian you want and what you want to spend. spending a little better for a tire that's higher tier even if you don't usually buy high tier parts is considered worth it, spending a little more for tires makes sense, the benefits are exponential.
right now you can use the silca calculator to get your proper inflation.
https://silca.cc/pages/pro-tire-pressure-calculator
>>
>>2018879
4130 refers to the steel of the frame. Measure the BSD of the rim, or read the tire. 90psi means to me it's probably a touring road bike tire, or an ancient mtb tire since one of mine is rated to 80psi.
Once you know the size and type of tire you need you can search or ask here.

I swapped out the crank on one of my bikes for a pretty old one. Now it makes a noise on every stroke of the pedal. I’m thinking the chainrings on the new crank are shark toothed but is there anything else it could be? I’m going to pull it and reinstall it this weekend just in case.
>>
>>2018950
Should have added that the cassette and chain are both brand new.
>>
>>2018950
Could be the chainrings are bent and your chain is hitting the FD(happened on a used bike I bought).
Could be the crank arm is hitting or the crank needs a longer spindle(doubtful). Could be your chain and cassette are good, but like you said the older chainrings are worn so... yeah.

Check everything, it should be obvious but sometimes it isn't.

lol Scotland has a lower population density and overall population than indiana

It has nothing to do with population distribution and everything to do with laws around planning

All the towns where I live are relatively small (10k-30k) and all have dense cores where people live in apartments above shops/restaurants/cafes, and then have regular houses with gardens outside the centre (but still easy to walk into the centre)

It is this localised density that allows for walkable areas around train stations that link them all together, and parking isnt a requirement because everyone lives close to the services

I've been to quite a lot of the USA and canada, and every small town I've been to has a car park for the town centre, and people don't live in the centre, it is all businesses with huge car parks and 4 lane roads with one crossing

I would say it is very subjective what is better, some people prefer living with everything on their doorstep, and some people prefer living far enough away from everyone else. It's just difficult for north america, as having things on your doorstep or close to public transport basically requires living in a major city, or in one of the few small towns that have it (due to the scarcity, these are always horribly expensive)

Only half true, but you wrote this like a massive cunt. If you're moving to a city just to sit inside all day and only leave to get groceries or whatever, then no shit youre not going to meet more people. But living in a city/walkable area makes you immensely more likely to actually do shit you like to do as easily as possible.

>lol Scotland has a lower population density and overall population than indiana
Typical /n/ cherry-picking and abject failure to understand geography.
Scotland has a lower average population density than Indiana because it's full of rugged highlands where it's hard for people to live and build homes. Plus, Scotland is often constrained by jagged coastline. Your 30k pop cities are clustered over relatively small areas.
Indiana meanwhile is flat, with some of the best farmland on the planet, a temperate climate, and almost no coastline. There are almost no geographic features in Indiana that would impede the spread of population. Furthermore, this geographic pattern extends into each of its neighboring states. Indiana's small towns are spread evenly across its entire area.
>It has nothing to do with population distribution and everything to do with laws around planning
The laws around planning evolve based on how the population distributes itself over time based on economic incentives and geographic pressures.
Funny how /n/ always fails so hard at such basic concepts.

What's a decently priced tubular tire to get (23-25mm)? Preferably with some light treads. I looked around locally and most of them are kinda expensive (continental alligators).

Are the Continental Giro's (28"x22"mm) any good for everyday use/long rides (concrete/asphalt roads)? These are in my price range but I'm willing to go lower.

I recently bought a classic steel road bike and this is my first time with a tubular. They currently have veloflex tires on them which are almost brand new but I want to get a new pair just in case of a flat or when I need to finally replace them.
>>
>>2018939
just get new wheels that aren't stupid, you might spend $250 for an entry level set. probably can find a nice used set since everything is thru axle disc brake now
>>
>>2018939
I don't know but bikeforums.net's classic+vintage section has a sticky about modern tubular tires. I would go there.
I know veloflex are some of the best, so you should be fine for a while. sew-ups are expensive since there is a very low demand. I would suspect simple cheaper tires to be around 40 usd, with nice ones being close to 100, and baller race ones even more.
>>
>>2018939
>Preferably with some light tread

not something you should look for in a road tire.
high end road slicks, like vittoria corsa, conti gp5k, or most models of tubs, with practically no tread pattern, have WAY better grip, on and offroad, than any treaded hybrid tire in the same size. This is as they use expensive grippy rubber compounds and are actually designed to be pushed in corners.

I agree you should get a clincher wheelset instead.
Trying to buy low-cost (still not cheap) semi-durable tubs is particuraly ridiculous, as tubs exist to achieve god tier ride quality and coolness . Unless you're prepared to minmax on a cafe bike they make next to no sense. Points into durability or value defeat the purpose of tubs.

Good news is that any bike you bought that has tubs is gonna be quite nice and worth modifying to be more practical.
I don't suggest you buy an entry level set of newish wheels. Black wheels ruin most classic bikes. You should try buy an older set with silver spokes. Sourcing good condition used wheels is very tricky as most people have no concept of brake track or bearing wear and are not transperant at all about condition. Contrary to popular belief, fucked nice wheels are worthless.

Still the most noble form of transportation is to be carried around by others, walking yourself is for plebs. Show us your palanquins then!

Only major changes since last posting is a less extreme angled stem and a riser bar. Pretty useable, makes sense to reach for the drops now occasionally. Still might flip the stem for even more comfort.

Maybe a bit bigger cassette in the rear for these mountain climbs. 52x39 up front and I've put on some weight this year. I've been back to tracking my diet so maybe I'll avoid the need to do that though.

Wheels definitely need to get trued this week,

part of it was for low maintenance. if something fucks up during work, you don't want to go home after 8 hours and then work more on your bike, you want to chill or do something fun. so less gears=less maintenance. if you're in flat-ass Manhattan, single speed is not as great of a disadvantage, but apparently they were popular in SF, too, which doesn't make any kind of sense to me . but when you're young and you want to flex, I guess they thought it made you cool
