From a very early stage the company worked with Raleigh , and was soon acquired by Raleigh , possibly also in Raleigh then used the Sturmey-Archer brand as its brand for components, particularly for its famous range of internally geared hubs. Sturmey-Archer hubs that I have worked in our workshops, many of which are still running to this day include the 3 speed K series first introduced in ! This is not to mention the endless variations of dynohubs. There was a time when so many AW s passed through our workshop that I could disassemble them, service them inevitably replacing the clutch and pinion pins and reassemble them in my sleep. Up until the mid s, Sturmey-Archer hubs were manufactured to the very highest tolerances and specification. These hubs were a joy to work on and genuinely seemed to roll on forever. The s in particular seemed to be a golden age of case hardening. Starting in the late s, the quality went gradually but inexorably downhill. It is a harsh truth, but by the mid s Sturmey-Archer hub gears could only properly be regarded as junk.

ALL Henry Sturmey was also editor of a cycling magazine and so ,from the beginning, Sturmey-Archer always saw the benefit of advertising. Many of the advertisements are no longer politically correct but reflect thinking at that time. Motor cycles were a booming industry in the early part of the 20th century and various types of engines and gearboxes were then produced. There was even a production unit in Germany and later, engines were supplied for lawn-mowers and small tractors.

Here can be found general company information, sales catalogues, prices and bike pictures through the years, newspaper articles, production information and factory views.

Patents for epicyclic hubs date from the mids. The first patent for a Reilly’s hub went into production as the first Sturmey Archer 3-speed. In , Mikael.

Template:Transmission types. Hub gears or internal-gear hubs are a type of gear system used on bicycles. Hub gears are used mostly on utility bikes and various types of small wheeled bicycle, such as folding bikes. Hub gears work by internal planetary or epicyclic gearing , which means that the outer case of the hub gear unit which is attached to the spokes is made to turn at a different speed relative to the rear wheel’s sprocket depending on which gear is selected.

In the United States and United Kingdom , hub gears are less common than derailleur gears which are the dominant gear system on most modern bicycles in these countries. In most of continental Europe, however, hub gear systems are more popular. Unlike derailleur gears, where the gears and mechanism are exposed to the elements, hub gears and lubricants are sealed within the hub of the bicycle’s rear wheel. Gears are changed by a cable which is tightened or loosened by a lever or twist grip on the handlebars.

Prior to using epicyclic gears in hubs of bicycles they were used on various locations of tricycles, there are a number of patents dating from the early s. The first patent for a compact epicyclic hub gear was granted in to the American machinist Seward Thomas Johnson of Noblesville, Indiana, U. This was a 2-speed but was not commercially successful.

This is my oldest-numbered currently useable Special Sports frame, V My guess would be that the frame dates to around , based on some other Speedwell numbers I have seen. I carefully used some very fine steel wool, with oil, on the frame and fork, which removed most of the yellowed varnish and, like a restored old painting, the areas of white became clear again. The process improved the colours, but I was extra careful around the decals on the forks and seat tube.

Also, some paint schemes may look better with the varnish left as is.

Thanks for this post, it is so clearly documented and photographed I’m inspired to start stripping one of my hubs! One question though, as the hub that most needs some attention is a Dynohub, I was wondering if you had any experience you could share relating to the risk of demagnetising the hub? Now how do we turn an AW3 into a 3SX? Having seen both of these hubs up close, it seems almost certain that the innards of the dynamo mechanism are identical, with the AWG also squeezing in a 3 speed gear mechanism too.

The instructions suggest that the dynamo mechanism can be removed as a single piece without demagnetisation being an issue. After that, the rest should be the same as the AW.

It is known in the art to provide three speed epicyclic gear hubs for bicycles by utilising planet gears engaged with a common gear ring and a sun gear fixed to the hub spindle. With this epicyclic system it is only possible to obtain direct drive plus one higher gear ratio and one lower gear ratio. It is also known in the art to provide five and seven speed epicyclic gear hubs for bicycles by utilising compound planet gears engaged with a common gear ring and each cooperable with a respective sun gear selectively engageable therewith in drive transmission mode.

The planet cages of the aforesaid arrangements are connectable with the hub shell, so as to provide a drive transmission from the planet cage to the hub shell according to hub condition, by means of radially or axially movable pawls mounted in the planet cage and cooperable with ratchet teeth provided in a hub end cap. The gear ring is connectable with the hub shell through radial pawls.

It is also known from EP 0 1 13 and EP 0 in the name of the applicants for a sun gear to be axially fixed with respect to the spindle and to provide a gear selector key movable axially of the spindle for selective engagement with a respective one of the sun gears so as to non- rotatably secure that sun gear to the spindle.

From Wikipedia the free encyclopedia. A hub gear , [2] internal-gear hub , [1] , internally geared hub [3] or just gear hub [4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed to the elements.

Changing the gear ratio was traditionally accomplished by a shift lever connected to the hub with a Bowden cable , and twist-grip style shifters have become common. Hub gear systems generally have a long and largely maintenance-free life though some are not suitable for high-stress use in competitions or hilly, off-road conditions. Many commuter or urban cycles such as European city bikes are now commonly fitted with 7-speed gear-hubs and 8-speed systems are becoming increasingly available.

Older or less costly utility bicycles often use 3-speed gear-hubs, such as in bicycle sharing systems. Many folding bicycles use 3-speed gear-hubs.
