===Kettenlinie===
===Kettenlinie===
Bei Fahrrädern mit Kettenschaltung funktioniert der Antriebsstrang noch ordentlich, wenn die Kette in einem sichtbaren Winkel verläuft. Das sollte bei einem Fixed Gear Fahrrad tunlichst vermieden werden. Hier ist es sehr notwendig, dass die Kette in einer möglichst geraden Linie verläuft.


Derailer bikes can work fairly well even with the chain running at a considerable angle, but this should not be done with a fixed-gear setup. It is quite important to get the chain line just right.

This topic is addressed at more length in our article on non-derailer drivetrains.
There is more detailed information on chainline in my Bicycle Glossary's Chainline Entry and even more in my Chainline Article.

The chain tension on a fixed gear is quite critical, and is regulated by moving the rear axle back and forth in the fork ends. If the chain is too tight, the drive train will bind, perhaps only at one angle of the pedals (chainwheels are not usually perfectly concentric). It should be tight as it can be without binding. If the chain is too loose, it can fall off, which is quite dangerous on a fixed gear.
