The Sturmey Archer clutch appeared in 1921 with the introduction of the K series hubs. Earlier Sturmey Archer hub gears did not have a clutch but used a completely different method of engaging the various gears. This article covers all Sturmey Archer clutches from 1921 except N.I.G clutches. Clutches for K Series Hubs K5   […]

Sturmey Archer sprockets can be a real problem on early (pre 1951) hubs. Early 12-spline and threaded sprockets are difficult to obtain and early threaded sprockets are difficult to change. I generally like to keep hubs in their original condition as much as possible, but sometimes a compromise is necessary. Threaded Sturmey Archer sprockets use […]

Sturmey Archer spares are available from many different places but not many sellers or repairers will be able to match the spare part with the date of your hub. Functionally this isn't really a problem as parts from early hubs are in many cases interchangeable with parts from later hubs. However if you want to […]

A rusty dynohub isn't necessarily a dead dynohub. Magnets and armatures can often be freed off and working perfectly again with some WD40 and gentle persuasion. Don't separate them though or they may never work again. Rusted chrome can be rubbed down and painted. Black looks good. This is not for the restoration purist though.

If you are offered a Sturmey Archer Dynohub that turns and you can feel a strong regular pulse, the chances are that it will generate electricity correctly and it will be worth buying if the price is low enough. If the pulse is very weak or non-existent it is unlikely to work.

I have been restoring some older Sturmey Archer Internals. I currently have two historic hub gear internals ready to fit AB or AG hubs. Sturmey Archer Internals Can Be Date Matched Pre 2000 A-series internals are interchangeable. A 1990s internal can fit into 1940s hub shell and will still work perfectly. However, if you are […]

When a bicycle needs repair often a replacement part will be required. A modern bike can be fitted with a modern part which is usually readily available. On an old bicycle it is often possible to get the bike back on the road by fitting a modern part, but in doing so we lose some […]

I've just taken delivery of a very large consignment of used and NOS Sturmey Archer spares and complete hubs. I now have a large stock of Sturmey Archer AG,and GH6 hubs which can be supplied as received or fully serviced. There are a few FG 4-speed hubs which will be reconditioned or stripped for spares, […]

I've been on eBay again, buying a few hubs that will be useful for the Sturmey Archer Course. One of the hubs is a AG 3-speed with dynamo. It is dated November 1959. Apart from the sprocket (which is no better than scrap metal) the hub is in beautiful condition. I love working on hubs […]
