What this chart is intended to be: This chart has been developed as an additional reference guide more so then simply dating off Sturmey-Archer hubs for the positive identification of Raleigh frames and entire bicycles. As proper factory documentation is very limited, the following charts are a constant work in progress; they have been compiled by examining numerous Raleigh frames from each period, component date codes, decal schemes, color availabilities per year; and – occasionally – official papers.

Many of them were staged, e. At a later date several cylindric hub, eg. For this reason it is mostly easier to open Sachs hubs. You will take a special tool for opening Sturmey-Archer hubs or it takes some tricks. Sachs did not use pawls for transmission power to the hub shell but the applied roller ramp clutches in their early days – which was already mentioned in other chapter. It took a while until pawls came into play. Sturmey-Archer’s pawls of the ring gear were mostly pivoted in pins, whereas Sachs turned to use easier and smaller pawls after the model They were pulled out of engagement together with the ring gear which needed a longer toothing therefore.

In the Sachs Elan, however, the ‘Sturmey-Archer principle’ was applied in the joint planet carrier with pressing pawls inwards for deactivating them. Sturmey-Archer built hubs with differential planetary gear trains in a very early time period, whereas Sachs realized this technology only in the Elan hub. The Elan contained two stepped gear trains coupled together, however, achieving a very uniform gear gradation.

Moreover, the principle of cam rods was very innovative from a technical point of view – but the triggering was pretty complicated and built rather large. The technology applied in the famous Duomatic and Automatic hubs is also very well-done. Though Bendix had some hubs in their program which changed gears by pedaling back some years earlier – it were the Sachs hubs applying a mechanism with pawls first.

how do you put a age to a sturmey arches sa hub. it is a 3spd one .sure that there is a way of dating them. Posted 9 years ago. IamSam. Member.

Two speeds currently function. It appears that the cage end cap and spring K45 and K46 are absent. I removed the star washer N from the r-h cone K6 which I probably shouldn’t have because you never mess with the right bearing no? I have tried holding it with a chain whip and hitting the keyways in K7 but that is pretty hard to do with only two hands and I am hoping there is a better way.

Any suggestions? I also tried undoing the RH ball ring K8 as I can get a good run at the keyways with a screw driver thread even with the sprocket installed. It hasn’t shifted yet so I have covered it with penetrating oil. Any other trick to this? Any suggestions of likely sources for K45 and 46? I guess the spring may be substitutable but I guess also that some of the pawl springs or or pinions may be too worn so I will probably need other parts too.

Assuming it’s like any other SA threaded driver, put a steel bar, like a headset spanner, lengthways in a vice.

Sturmey-Archer was one of two major manufacturers of internal-gear hubs in the early and mid 20th century. Shimano has made internal-gear hubs since The Sturmey-Archer AW 3-speed hub, by far the most popular one, was durable and, easy to maintain and rebuild. Quality issues also began to creep in. Sturmey-Archer history is covered in the book The Sturmey-Archer Story and its online update by Tony Hadland ; bits and pieces of the history are in the technical articles on this site.

It is tempting to assign other undated hubs to the second world war, but we would sometimes be mistaken. Some of the undated A series and F series hubs that I have seen are clearly from the period. As a guide:. Why hub are undated remains a mystery. Find out more. Okay, thanks.

The first 110 years….

Last fall I relocated our offices to the Laurelhurst neighborhood in Northeast Portland. I restored both bikes many years ago, but the Peugeot was a more involved process because many of its original parts were missing. The restoration process involved sourcing a vintage b wheelset and fenders, as well as handlebars, stem, brake levers, saddle, dynamo, lamps, and saddle.

My goal was to come as close as possible to the bike featured in this Peugeot catalog, and to err on the higher quality side when possible. I think I achieved this objective and am happy with the way the build came together. The NOS Ducel dynamo lights work well without excessive drag.

My Maclean Featherweight with a Sturmey-Archer FM hub came with an incorrect trigger. I wanted to install a period-correct trigger and so.

Sturmey-Archer is a manufacturing company originally from Nottingham , England. It primarily produces bicycle hub gears , brakes and a great many other sundry bicycle components, most prominently during their heyday as a subsidiary of the Raleigh Bicycle Company. In the past, it also manufactured motorcycle hubs, gearboxes and engines.

All Sturmey-Archer gear hubs use epicyclic planetary geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple planetary geartrains. Depending on the specific hub these may be in series with each other, or with one or the other set being selectable at any given time by locking a particular sun gear to the axle.

In , the K hub was introduced as an updated and improved version of the X, later FX hub following the introduction of fine axle threading – it is the Model X which was manufactured under license by BSA as their 3 speed hub until Most notable was the 6-prong ramped sliding clutch which was mounted between springs, this gave the advantage of lateral movement being possible without shifter movement and allowed gears to be pre-selected while pedalling, the ratio would change when pedal force was relaxed, freeing the mechanism to slide into the new gear and under spring pressure.

The ramped clutch dogs and sprung mount also permitted the K hub to be without a neutral position between the ‘Normal’ direct drive gear, and the ‘High’ overdrive gear, both the SW and AW until the mid s have this neutral position. The gear ring dogs would ratchet around the clutch using the ramps and springs if the hub was trying to engage Normal and High gear at the same time, though allowing this to happen through slow shifting can cause excessive clutch wear and render the hub inoperable.

In Low gear, this isn’t a problem as the low gear pawls can be overrun by a higher gear, while Normal and High gears use the same pawls, requiring an alternative solution. The K hub spawned a Tricoaster version with back pedal brake, designated KC, in and both close ratio KS , and medium ratio KSW variants in and respectively. The KB was joined in by the KT mm tandem drum brake, part of a family of mm drum brakes alongside the BFT and BRT front and rear drum brakes BR type drum brakes are not gear hubs and are instead threaded for fixed sprockets or freewheels.
