That's not true either. It is possible to lean a bike sideways you know.if the top tube is the right length and that is the most important measurement to you, and you can't quite stand over the bike, you can lean it sideways, if you can't trackstand that is ya noob.

And don't kid yourself with hipsters have shorter stems cause leaders and the likes have longer top tubes. They have longer top tubes cause the top tube is stiffer than a stem, so you can have s shorter stem and a stiffer bike for track racing. Part of being a hipster is that you don't race track. They have them cause they either do bar spins, where you need it to be shorter so your bars clear the top tube, or cause it looks cool.
