>>1277100>Steel frames are shittier than carbon and especially aluminum constructions.They are heavy. Only downside.
>airlinersSteel plane will weight too much
>brake leversDoesn't fucking matter. There are a lot of made of plastic, shit works.
>crankWell, depends on tast
>(front)derailleursSteel would be superior here, since there are alloys, that won't bend easily.
>hubsSteel would be better, yet in some cases, like electric hub motor, alumiuim is the only option.
>rimsAluminium. Steel one would be heavier, which is not good for suspension, and it will have thinner walls, which is bad for v-brakes.
>handlebarsDoesn't fucking matter.
>stemsDoesn't fucking matter.
>seatpostsSteel is better. Because aluminium is much easier to bend accidentally
>forksActually depends. If it has suspension - aluminium will make more sense. If it doesn't - steel is the better choice.

>quik release handlesNo fucking quick release. Just nuts and bolts, otherwise niggers steal the wheels and shit. Bonus points for weird nuts.

Aluminium has one benefit. In can be extrudes to whatever form you want, which makes irreplaceable for kick-scooter frames, because there every fucking millimeter counts, and every fucking gramm.
In bicycle weight is not that important, as long as you can lift it, you're good to go.
>>1277085Actually you can make it develop a crack from fatigue, but I have no idea how you should abuse a bike in order to do so.
While on aluminium it is much easier.
For example, electrical kick scooter fork. There are ones made from aluminium, which have a tendency to crack, since motor stresses it during acceleration. There are steel ones, which weight slightly more, yet don't give a fuck about motor stress.
