is there even a point in this
A G G R E S I V E G E O M E T R Y? I mean this page is for buying and selling bikes in NYC so most of these bikes are meant for urban commuting with a small percentage of messengers. Would this even be practical or do these fucks just want to look cool hunching over at a negative angle while navigating traffic?

They give you about a 2-5% advantage, moreso at higher speeds.
Important if you're doing 400W down the french countryside but if you're a hipster whose AIDS legs can't manage more than 100, then this aggressive 'fuck me in the ass' position is more for retaining flexibility for when big boys want to fuck them in the ass.

most of the people on this page are beans. As are, apparently, most messengers in NYC, not really hipsters, but working class. Also what is the practicality of having no brake fixed gear in the city? Another side effect of "Fixed gear no brakes cant stop dont want to"?

Are you such a faggot that a 5km commute in a aggressive position will leave you handicapped? It's not like the wind doesn't exist in the cities.

It's a commute, dude. When it's raining, cold and you're tired, going into full aggressive aero position on your fagboy fixies seems less appealing

I'm as far from jerking over fixies as you can be. I commute on my roadbike, but really just a few thousand km will get you used to any position, and I'm really enjoying lots of agility that riding in an aero position in drops allows.

I ride in the drops on my commute too. Just not that aggressive.

I've got a really agressive bike, I'm young and limber though so it's not painful.. It's about 30cm from my saddle to my drops and I commute 20km each day and regularly do 100km+ rides.

Maybe when I get older I'll go to less agressive setups, but I enjoy the a e s t h e t i c and I can use it so why not?

Even from a pure performance viewpoint it doesn't make sense. There *is* a such thing as too low where you actually become less aerodynamic, especially when you have to raise your head more to see. And your hip angle becomes so small that your veins are pinched and you can't really push your pedals properly. You look at the pro TT rigs, they all have some amount of stack on their bars, and it's definitely not because they aren't flexible enough to go lower.

Going fast in city traffic can make you safer. Less cars passing you. drop bars, big drop, fattish tires

umm
pppppppp

BUT lemme tell you some of us have weird proportions. Take a 6'5 lanklet with relatively short torso and you'll see what some real drop looks like boi

Drag is a function of the square of the object's velocity relative to the medium.
It means that when you go faster, the air pushes back harder.

Most messengers I have seen have pretty reasonable riding position. Some quite upright.

The geometry comes from competitive track bikes, where speed/aero is important. A few spilled out and surely some people like the way they look.

As someone else said, messengers probably choose fixed/ss for ease of maintenance. It's not a high paying job. Gears are really nice, but ss just works. Flexible as far as chain usage and crank type and hub types. Put it together and ride till the chain stretches out without adjusting a thing-

I refuse to believe that maintenance on a decent 21 speed is a significant factor. unless you treat you bike like shit or fuck with the screws you will not have to do anything but lube the chain up every few months by most people's standards.

Cassettes cost $30-40. Chains cost $20.
You have to replace chains when the shifting degrades, and then you may also have to replace the cassette because it's worn and your new chain is not. Only the middle cogs actually need replacing but you have to replace the whole thing because that's how they come. You never have to worry about that with fixed because there's no shifting so the chain and cogs just wear into each other until there's virtually no teeth left. Then there's derailleurs and shifters which can occasionally break down, and cables which regularly break or fray. This stuff might not happen much if you only ride in good weather but ride through a winter and you start to realize how fast components can break down.

its a common mistake thinking that ride geometry increases efficiency. its really all about matching your socks to bar tape, helmet etc.

It's not maintenance, but rather resilience to damage and reliability even when abused and not maintained. Can't tweak a single speed like you can a derailer.

Your beliefs are totally irrelevant to everyone else. Nobody will ever care about what you believe with regard to bicycle maintenance.

Sure, but most people that ride often don't abuse their bikes and do at least a little maintenance.

It's more or less after a 10hour work day as a messenger it's more appealing to clean a chain and maybe replace a tube/tire than having to adjust a derailleur, breaks, clean a cassette etc.

Learn to own a bike first, then complain here.

You adjust your gears once, you adjust your brakes once, and you clean your cassette whenever you usually clean the rest of your bike.

The best TT riders don't ride anything like this shit. Even a tall guy like Froome has an immaculate position and it''s flat, everything is flat. Not down.
