>>1666046>and then find bikes like this and measure the stems and forks etcWhat do you mean measure? The geometry of the bike comes from the angles. That shit comes with their prebuild bikes in the spec sheet and a lot of those numbers are very close depending on the type of bike(road, trail, xc, enduro). The forks are dependent on the frame(you can't put 170mm suspension fork on a frame built for 120mm forks) for example. Stem length and steerer tube widht are also somewhat dependent on the type of bike(as well as personal preference)
>You could pick a bunch of random teenagers and show about 80% of them how to build a functioning computer within a couple of hours from literally watching one youtube video and not providing any direct helpMy point is that bike assembly is exactly the same. With a few videos literally anyone could put a bike together, within a few hours, provided they have the tools. I'm curious, which part of a bike assembly do you think is so complicated that the average person would have trouble with?
