In diesem Artikel werden die verschiedenen typen von Bremsen betrachtet, die an Anlötsockeln des Rahmens oder der Gabel befestigt werden und zwei separate Arme je Bremse haben. Im Zusammenhang mit diesem Artikel solltest Du auch Das 1x1 der Felgenbremsen lesen. Dort werden unter anderem auch folgende Aspekte erläutert, die auf alle Arten von Felgenbremsen zutreffen:

  • Warum Felgenbremsen?
  • Typen von Felgenbremsen
  • Zentrieren
  • Hebelübersetzung
  • Geräusche/Quietschen
  • Typen von Bremsschuhen
  • Einstellen der Bremsschuhe

Die meisten Probleme mit Felgenbremsen werden durch exzessive Reibung oder schlechte Montage der Züge verursacht. Schlechte Einstellung oder Bremsen geringer Qualität sind zumeist keine Gründe.

Cantilever- und Zangenbremsen

Bicycle rim brakes divide into three basic types. Just to recap:

Cantilever brakes have the brake shoe and cable attachment on the same side of the pivot (cantilevered). All of these brakes require special brazed-on fittings on the frame. These fittings are commonly called "studs" or "bosses."

U-brakes and Roller-cam brakes have the cable and brake shoe attached on opposite sides of the pivots, which are brazed on.

Caliper brakes have arms that reach downward from above the tire, and need to be long enough to get around the tire. The article on caliper brakes describes how to work on these brakes.


Typisierung von Bremsen an Anlötsockeln

This page leads to four separate pages, each dealing with a different sub-type. Click on the heading below to go to the relevant page: Direct Pull, "V-Brakes ®" This is the type most commonly used since the mid 1990s. This is the only style of cantilever brake where the cable comes to the cantilever set from one side, rather than down the middle. Direct Pull V-Brake Center-pull (Traditional) Cantilevers These were used on almost all mountain bikes made before the mid 1990s, and are still popular on touring and cyclocross bicycles. This type of brake should be used with a fender, reflector bracket or other device to prevent the transverse cable from snagging the tire if the main cable parts.

See my separate article on adjusting this type of brake Traditional Centerpull Cantilever U-Brakes These were fashionable for mountain bikes around 1987, typically mounted underneath the chainstays. The pivot for each brake is between the brake shoe and cable attachment, and so these are not cantilever brakes.

U-brakes have had a bit of a revival in the last few years for use on freestyle bicycles

(Functionally, U-brakes are very similar to the center-pull caliper brakes popular on sport bikes of the 1960s and '70s.) U Brake-eye bolts Roller-Cam Brakes The Roller-cam brake was a predecessor of the U-brake, and had a brief vogue in the mid 1980s. The pivot for each brake is between the brake shoe and cable attachment, and so these are not cantilever brakes.

Direct-pull cantilevers require special brake levers. Direct-pull brake levers pull the cable twice as far, half as hard. It is not generally safe to mix and match levers/cables between direct pull and other types for this reason.

  • Conventional brake levers used with direct-pull cantilevers will usually not pull enough cable to stop in wet conditions without bottoming out against the handlebars. In dry conditions, they either won't work, or will grab too suddenly.
  • Direct-pull brake levers used with any other type of brakes will feel nice and solid when you squeeze them, but you'll need to squeeze twice as hard to stop as you should, so unless you are a lightweight rider with gorilla-like paws, this combination isn't safe either.
