===Vertikale Ausfallenden===
===Vertikale Ausfallenden===
Die meisten neueren Fahrräder seit den 1980er Jahren haben vertikale hintere Ausfallenden, bei denen das Laufrad aufwärts schiebend montiert wird. Wenn man das [[Schaltwerk]] loswerden möchte, wird das zum Problem, weil man nun eine Vorrichtung benötigt, mit der man die Kettenspannung regulieren kann.

Most newer bikes (made since the late-1980's) have "vertical" rear dropouts, where the wheel slides upward as you install it. These are a problem when you want to dispense with a derailer, because you need some way to regulate chain tension.

Not a dropout!
You CanNOT use any sort of pulley type chain tensioner on a fixed gear bike!


You cannot use a derailer on a fixed gear bike, even as a chain tensioner, because when you resist the rotation of the pedals, you would bend the derailer. This presents a problem if you want to use a frame with vertical dropouts as a fixed gear, because there's no easy way to adjust the chain tension. This is also true of chain tensioners sold for singlespeed coasting bikes, such as the Surly Singleator.
