Sturmey-Archer Naben
Old English Almost all English 3-speeds have Sturmey-Archer rear hubs, and there have been many different models since the company started in 1902. Sturmey-Archer was a division of Raleigh Industries until autumn, 2000, when the parent company ran into financial difficulties. Sturmey-Archer (U.K.) was rendered homeless by various corporate maneuvers. For a while it appeared that it would disappear entirely into bankruptcy. The land the factory stood on was sold, and Sturmey-Archer was nearly liquidated by a corporate raider. Fortunately, a Taiwanese company called SunRace came to the rescue, and bought the company assets more or less intact. The machinery and stock were moved to Taiwan. SunRace resumed production of Sturmey-Archer hubs -- some pre-existing models, many new ones.
Sturmey-Archer quality had been on a downward slide since the early 1960s, as the company's engineering efforts shifted from trying to make a better product, as they had been through the first half century, to finding ways to make an acceptable product cheaper. Sturmey-Archer's quality peaked probably in the late '50s.
SunRace spent a great deal of money moving the machinery from England to Taiwan, but when it arrived, it turned out that most of the machinery was worn-out junk, no longer capable of manufacturing parts to the degree of precision appropriate to the 21st century.
I heard an interesting anecdote from a Sturmey-Archer veteran employee, now with SunRace/Sturmey-Archer: Back in the day, sometimes a batch of internal parts would be just a bit out of tolerance, maybe a bit too small, or a bit too large, whatever. The production people would take a sample to the engineering department, where a grey-haired engineer would check it out and often say "Well, it is a bit out of spec, but not really enough to cause failure, so let's let it go."
SunRace didn't have those engineers who had grown up with Sturmey-Archer in their blood, so when they found a batch of out-of-spec parts, they would say "That's out of spec! Melt it down, and make new ones, and do it right this time!"
In any case, the quality of Taiwanese production from SunRace/Sturmey-Archer so far has been excellent, generally better than the quality of later English production. Sturmey-Archer's selection of multi-speed hubs is much wider than that of the other manufacturers. Sturmey-Archer hubs tend to be lighter than the competitors'. SunRace has also introduced many new models, including an 8-speed internal-gear hub, a fixed-gear three-speed and an updated version of the Dynohub generator. Many Sturmey-Archer hubs -- even the 8-speed -- can fit the narrow dropout spacings of older bicycles. .
Some folks don't believe that the Taiwanese can make stuff as well as the British did, but there's no factual basis for that belief, and in many cases this attitude may be traced to racism.

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. |

New version similar to the AW, with an aluminum shell. Improved pullchain interface; no brake. |
SW |
3 | Superwide | 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 shape 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. |

AT5 |
5 | Wide | Aluminum shell, 70 mm drum brake, single cable; introduced in 1993 | |
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. | |
