Übersetzungen

Die üblichen Sturmey-Archer Drei-Gang-Naben haben im mittleren Gang eine direkte Übersetzung (1:1), im höchsten Gang 4/3 der direkten Übersetzung und im unteren Gang 3/4 des mittleren Gangs. Das Prinzip, die das erreicht wird, wird in einem anderen Artikel erläutert. Unter anderen aktuellen Naben ab 2010 ist die S3X Fixed-Gear Nabe abweichend zu dieser allgemeinen Aussage. Sie hat zwei nah unten abgestufte Gänge und eine direkte Übersetzung im höchsten Gang. Zudem gibt es noch eine spezielle Nabe für Brompton, die eine breitere Übersetzung hat und mit zwei Ritzeln und einem Schaltwerk insgesamt sechs Gänge hat.

Nach modernen Maßstäben ist das typische englische Drei-Gang-Fahrrad recht hoch übersetzt. Die meisten haben eine 48/18 Kettenblatt/Ritzel Kombination mit einem Vortriebsverhältnis von 3,83, 5,11 und 6,81 (Entfaltung von 4,00, 5,28 und 7,12 Metern). Hier kann man das Fahren etwas vereinfachen, indem man die Kettenblatt/Ritzel-Kombination anpasst. 20er oder 22er Ritzel sind leicht zu bekommen. Genauso kann man auch kleinere Ritzel erwerben, wenn man ein Geschwindigkeitsfetischist ist oder ein Fahrrad mit kleinen Laufrädern hat. Auch kann man sich ein Shimano Ritzel mit einem Dremel anpassen, wenn man ein noch größeres Ritzel fahren möchte. Das ist nicht besonders schwierig und wird im Artikel Alles über Nabenschaltungen erläutert.

Sturmey-Archer hat viele Modelle der Drei-Gang-Nabe über die letzten Jahrzehnte entwickelt.

Dokumentation aktueller und moderner Sturmey-Archer Drei-Gang-Naben

Sturmey-Archer has the widest surrent selection of three-speed hubs of any manufacturer. Most have aluminum shells, and are relatively light compared with hubs of other brands. The information below is compiled from a review of the Sturmey-Archer Web site, Sturmey-Archer catalogs, and a Web search. Technical information is available for most, but not all, current Sturmey-Archer 3-speed hubs. The newest three-speed coaster-brake hubs have been added to the comparative parts lists in Sutherland's Handbook of Internally Geared and Coaster Brake Hubs, now online on this site.

Rows with yellow backgrounds in the table below are for hubs which are lsted in both the 2010 and 2015 catalogs. Links in the "Model" column will take you to Sturmey-Archer's page about the hub. Rows with green backgrounds are for hubs new since 2010. Rows with white backgrounds are for "ghost" hubs -- no longer sold, not in the 2015 catalog, and parts may no longer be available. On the other hand, many parts lists are available which were not in 2010, listed in the Documentation column.

Old English Almost all English 3-speeds have Sturmey-Archer rear hubs. The classic Sturmey-Archer AW hub is by far the most common model. It is quite easy to overhaul with these instructions. Parts for the classic AW are available from Harris Cyclery, and this hub is so common that parts can often be cannibalized from discarded wheels. (The current No Intermediate Gear version of the hub is not the old AW. It is mostly the same as the S-RF3 hub except for its steel shell.)

There have been several licensed and unlicensed copies of the AW: Brampton, Hercules, Scintilla, Steyr, SunTour, Vibo. Most parts are interchangeable.

The table below covers the more common older hubs and a few others of interest. It omits specialty narrow-ratio hubs and hubs discontinued before 1940. Old Sturmey-Archer three-speeds other than the AW and closely-related models (AG, AB) can be tricky or impossible to repair, due to parts un-availability.

Sturmey-Archer changed its parts numbering system sometime around 1950. Older parts numbers begin with the letter K and newer ones, with H. If the model of the hub is the same, and the description of the part is the same, the part is almost always the same, despite the different numbering. Some of the classic references linked below use the "K" parts numbers. Sutherland's Handbook of Coaster Brake and Internally-Geared Hubs uses the newer part numbers.

Older internal parts with a gray finish are reportedly more durable than newer ones with a black finish, due to a better surface-hardening treatment which had to be discontinued for environmental reasons.

The AW's internals will fit into many Sturmey-Archer hub shells of the same era, making it possible to keep a wheel in service. One exception is that the left ball cup of many if not all four- and five-speed hubs lacks an inner flange to center the planet cage. Sturmey-Archer historian Tony Hadland reports that 1984- and later steel AW shells will not accept S5 internals. Coaster-brake and drum-brake shells will not fit the AW.

Older Sturmey-Archer coaster-brake hubs have safety issues: The brake of the TCW and S3C was actuated through the gear train, so it was weakest in high gear, when the bicyclist was going fastest! The TCW could lose the brake entirely if the cable was misadjusted, due to the neutral-gear position between second and third,. The AW and its near relatives also have a neutral gear, and if the cable is misadjusted, these hubs can drop out of gear. Jobst Brandt has, in addition, described a tendency of these hubs to slip out of high gear into neutral in a hard sprint -- though this problem does not occur under more usual conditions of use. See comments on this topic by Brandt.

The Web sites linked below the table cover many additional older hubs. The Sturmey-Archer Heritage Web site has a wealth of historical and technical information. Tony Hadland's Web site includes an exploded drawing and parts list for nearly every Sturmey-Archer model up through 2001, as well as rebuilding information for many older hubs. Documentation on the older hubs is actually better than on current ones.
