Pattern Sturmey Archer Indicators from Colwood Wheel Works My engineer is now making pattern Sturmey Archer indicators and toggle chains for K, TF, FW, FG, FM, FC hubs. These hard to find parts are now available. I examined two prototypes which were very good indeed. Just a couple of very minor changes were required which […]

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 […]

I went into the workshop this afternoon with the idea of tidying it up a bit. Seeing the FW axle in the vice I began to clean some more of the parts.  Having started I couldn't stop so the hub is now completely rebuilt, lubricated and polished. The FW is now looking good and running […]

I'm currently servicing 2 FW four-speed hubs for a friend. One of them is in very nice condition and needs nothing more than a good clean and lubrication.   I opened the gear and examined the internals as my friend requested and stripped it down as far as the planet cage.  There was no need to […]
