This page describes Sturmey-Archer hubs from the 1930s onward, and gives links to information about them on this site and others.
Our pages about servicing Sturmey-Archer hubs will guide you to the best information we could find, including information no longer available from Sturmey-Archer, so, let's first list those pages here:

Rows with white backgrounds in the table below are for "ghost" hubs -- no longer sold, not in the 2015 catalog -- though some of these are very common, or mostly the same as current hubs. Rows with yellow backgrounds are for hubs which are in both the 2010 catalog and the 2015 catalog. Rows with green backgrounds are for hubs in the 2015 catalog only. Hyperlinks from the model numbers in the left column will take you to servicing information on individual hubs. For old hubs where there is no hyperlink, look on Tony Hadland's site, the Sturmey-Archer Heritage site or the Veteran-Cycle Club library site (Links at top and bottom of this page). Harris Cyclery, SJS Cycles and Oldbiketrader in the UK maintain stocks of discontinued Sturmey-Archer hubs and parts.

QS-RC3 |
3 + reverse |
Wide | 133.3 100 75 |
Coaster brake, aluminum shell, reverse gear and second sprocket, made for a tricycle. This is a gearbox, not a hub and must be used in an intermediate position on the frame, with input and output chains, because the secondary sprocket attaches where the spokes would. |
RS-RB3 |

SBR |
3 | Wide | 133.3 100 75 |
"Steelite" with 70 mm drum brake.
"Steelite" indicates a hub with a steel shell. |
S3C |
3 | Wide | 133.3 100 75 |
Coaster brake. After Consumer Reports rated the TCW IV "unacceptable" because the brake would fail completely if the shift cable was misadjusted, Sturmey-Archer completely redesigned the Tricoaster, so that the braking was independent of the gear-change. This model is safer than the TCW series, but is still prone to failure. Also see rebuilding instructions in Sutherland's Handbook of Coaster Brake and Internally Geared Hubs. |
S3X |
3 | Mid | 100 75 62.5 |
SunRace/Sturmey-Archer's new-production 3-speed fixed gear, supplanting the rare ASC. A matching front hub, the HBT, is available. |

3 | Wide | 133.3 100 75 |
Aluminum-shell version of the AWC(II), with coaster brake. |
S-RF3 |
3 | Wide | 133.3 100 75 |
New version similar to the AW, with an aluminum shell. Improved pullchain interface; no brake. |
S-RK3 |
3 | Wide | 133.3 100 75 |
New version similar to the AW, with an aluminum shell. Improved pullchain interface; disc brake fitting. |
SW |
3 | Super- wide |
138.4 100 72.23 |
This model was intended to replace the AW in 1957, but was so troublesome that it was withdrawn, and the AW re-introduced in 1958. The SW uses a unique 3-prong driver, and has crescent-shaped pawls that don't use pawl springs. When they work, they're very nice. They are light, nearly silent, and efficient. None of the internal parts are interchangeable with other models. See Brian Hayes's article on this site. |
SX-RB3 |
3 | Wide | 133.3 100 75 |
Wide-body 3-speed (for wide dropout spacing) with threads on left side for band brake drum or sprocket. |

TS-RB3 |
3 + reverse |
Wide | 133.3 100 75 |
Threading at left side for band brake -- could be used for a drive sprocket. High-polish aluminum shell, reverse gear and second sprocket: made for a tricycle. This is a gearbox, not a hub and must be used in an intermediate position on the frame, with input and output chains, because the secondary sprocket attaches where the spokes would. |
TS-RC3 |
3 + reverse |
Wide | 133.3 100 75 |

AB-5 |
5 | Wide | Steel shell, 90 mm drum brake, introduced ca. 1999 | |
AT5 |
5 | Wide | Aluminum shell, 70 mm drum brake, dual cable; introduced in 1985 | |
S5 |
5 | Wide | The earliest 5-speed hub, a modified FW. The original S5 used two cables, a conventional 3-speed type on the right, and a bellcrank/pushrod unit on the left. The right lever/cable has 3 positions, and works as a normal 3-speed hub. The left lever/cable converts the hub from a medium ratio to a wide ratio 3-speed. Since the middle gear is direct drive, the left control has no effect on the middle gear.
Most, if not all Sturmey-Archer 4-speeds can be converted to 5-speeds. The planet cage is the same but the axle and large sun gear must be replaced so they engage in both directions. See additional information. Also see rebuilding instructions in Sutherland's Handbook of Coaster Brake and Internally Geared Hubs. |
|
S5/1 |
5 | Wide | Replaced the S5; used two pullchains rather than having a bell crank on the left side. Unreliable, tended to pop out of low gear. Also see rebuilding instructions in Sutherland's Handbook of Coaster Brake and Internally Geared Hubs. | |
S5-2 |
5 | Wide | Improved, reliable version of the S5/1. The S5-2 has a bit more internal friction than the plain S5. Axle assembly and axle gears are different. Also see rebuilding instructions in Sutherland's Handbook of Coaster Brake and Internally Geared Hubs. | |

Ratios are the same as pullchain-shifting hubs, and installation instructions and specifications are for a hub with a pullchain. Coaster brake, reverse rear and second sprocket. This is a gearbox, not a hub, and must be used in an intermediate position on the frame, with two chains, because there is a bracket that goes across where the spokes would be. |
