Sturmey Archer Sprocket Problem Solved

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 the same thread as standard fixed sprockets so it is possible to fit a fixed sprocket if an original threaded sprocket is not available.

It is possible to use modern Sturmey Archer sprockets (which are easily obtained and easily fitted) on a pre 1951 hub if you are happy to have the driver changed for a modern equivalent.

Changing a driver is a relatively simple task which you could do yourself. Alternatively I will very happily do the work for you.

  1. I’ve got both a TF and a TC hub and I’m looking for 15 and 16 t cogs in the 12-spline pattern; or, better yet, looking to see if the 12-spline drives on these hubs can be replaced with drives that take later 3-spline cogs.

    Is this possible, and can you do it?

    If not, can you supply — or find — 12-splined cogs in a 15 t size?

    Many thanks.
