I don't think type of joints matter, if speed is lower than 130 km/h.
If speed is higher, you obviously want to weld it, because at such speeds you can actually crack a wheel, and nobody likes flying chunks of steel flying at 180 km/h

You should use these. There is absolutely no reason not to. If you reject these because they are not ''cool'', you are a tosser.

Also, of all bikes, mountainbikes are the one who needs FENDERS the most. Think about it. It's time we put this trend in motion. Do you see dirt bikers riding without fenders? Of course not !

>inb4 clogs up
there are special fenders that prevent this but still provide fender action.

WM is the sheistiest waste removal service ever. My parents have a business with their waste contracted to WM. One time my parents' business had an influx of waste, overflowing their bin. WM refused to pick up unless an overflow bill was paid. They sent pictures along with a couple hundred dollar extra bill, it was so BS my parents contracted to FloodBros the same day instead. Monthly fees are now like more than halved as well as no issues with bin overflow.

Anyways, I hate riding behind garbage trucks but I find the logistics of waste services fascinating

Unironically garbage collectors and sanitary workers do more work for society than any other job. They are the ones that should be celebrated not the fucking troops or cops. A clean street will do more to prevent crime than a cop doing 20mph through a residential neighborhood.
I will never ever make fun of anyone with this job because they are the ones that make the world go round.
So if any of my a/n/ons are a sanitation worker, you deserve the best.

With bottom brackets, 68mm refers to the body of the cartridge and the second number is the length of the axle poking out either end right? My BB doesn't list the second length, I can just measure it and it won't matter if I'm out by a mm or two, right?
>>
>>1430489
It's the entire spindle length, yeah.
it -probably- doesn't matter if you go off by a little but sometimes your fd's limit screws have no adjustment left so can't handle any more change, and sometimes your clearance getting smaller is an issue and it does suck to make your q-factor gratuitously wider.

Also the BB in your bike now is not even necessarily the ideal length.
>>
>>1430490
I just measured it twice and read it as 115mm. Shimano make 115mm BBs so I suppose I'll just go with that.

They were in pretty much the worst possible places in relation to one another, neither pilot could see the other plane. I'm not sure if they were trying to hold formation or if they didn't know they were so close to begin with but if it's the former they violated pretty much every cardinal rule of formation flying, most importantly the one about keeping the leader in sight at all times.

Your attention please!

Size your frame correctly. Stop using 30mm setback seatposts. It looks dumb. It looks like you bought the wrong size bike. Same goes for you dorks riding 130mm stems. Cut that shit out. You look like you stole a child's bicycle and slapped on some accessories.

>but I like the way it rides
No, you are objectively wrong and you've just trained yourself to like something bad. An imaginary line drawn between the tips of your bars should touch the leading edge of your headtube and the center of your saddle should be directly in line with your seat tube.

Thank you for your attention to this important matter.

>>
>>1430266
Having odd proportions is a pain when buying bikes. You gotta look through geometry charts to try and figure what has even a small chance of fitting you. My problem is that I have super short torso and long ass legs, especially my tibias are long. So I'll have a super high saddle but can't have too much reach. Luckily I'm flexible and can work with plenty of drop. But I have either a zero setback or set-front seatposts on all my bikes because otherwise I'll be pushed way too back.

>>1430308
I've got a friend with simmilar issues.
He needs a ridiculously tall frame, about 65-70 cm, idealy with 200-220mm cranks and a 70T big ring because of his absurdly long legs and low cadence while requiring a pretty short reach and tall as fuck stack height.
Wich is funny because I'm the exact opposite and can push up to 32 km/h in 34:28.
I'm considering to use the seatpost of a folding bike, a steerer tube extender and a steeply pointed up stem to build him something that fits at least a little.

It's not "all" of the QBP bikes. Maybe half? And they tend towards dirt/downhill for the ones that are. The only All City bike I see like that is the Electric Queen.

Most road focused bikes have 5-7 frame sizes.

Every single bike across the entire company has a geo chart too.

Rode for the fist time on a modern mountain bike just recently. It's hard to tell if the confidence it gives you is waiting to bite you in the ass. I mean downhill on gravel on skinny 26" tires you are fighting to keep them from digging in, with plus size and larger tires it's like you are gliding over the top, but I wonder if they are just waiting to dig in and it will be harder to notice/control because you are not feeling it as much.

An electric circuit needs a live line and a return line. Hence a circuit. Think of it like a pump, water pipes and a water wheel,where you want to pump water through the pipes to move the water wheel. The pump needs the water to return after moving the water wheel so that it can pump it again, so a circuit of water. Roughly, that's how the electrical circuit works, it needs the electricity to return to the generator. Railways use the rails for this return, but trolleybuses can't, so they use the second wire. Does that clear it up?
Now a streetcar can share the live wire of a trolleybus overhead line, as in the pic, and it still uses the rails for the return, while the trolleybus uses the second wire.
A problem would arise if you somehow connected the two wires directly, as the circuit would overload as you've removed the resistance. Like if you remove the water wheel from the water circuit and the pump overloads because the water moves ever faster, that would be the simile. Hence: short circuit. The circuit lacks a resistance and overloads. Thats where the circuit breaker switch comes into play, it breaks the circuit to prevent the electrical system to catch fire from the overloading heat.
The pantograph is simply a contact surface, but it's wide, so if it were running on the trolleybus wire it could touch the return wire, thus connecting both and causing a short circuit.
