    A friend In Dorset has a Sturmey archer 5 speed, she has trouble selecting gears and i believe the unit needs a service or repair (it is not just the cable adjustor). Can you advise a competent person who could service the hub?

    • Hi Mike,
      There are a number of people around who could tackle the job. I usually do my own repairs but unfortunately cannot take on extra work. But I have used Peter Read in Milton Keynes (even on a hub that was about 100 years old) and he has been fixing hub gears for many years. His email address is
      If you cannot resolve the problem via Peter, please get back to me.

  2. “How to repair old Sturmey-Archer hubs HADLAND’S BLOG” was a wonderful read and I actually was indeed pretty content to find the blog. Thanks for the post-Maura

    Found an old Dynohub at a recycling centre (on its way to be crunched) and really appreciate the info you provide – i’ve got no excuse to revive it now! I’ll certainly recommend it to other Sturmley Archer fans – Many thanks – Surely this is what the internet was created for!

    Thank you so much for this information. I was having trouble understanding the light set and DBU wiring on my 50s Raleigh 3 speed and now it is well on its way to be fully functional. :)

    Thank you for making these documents available,just rebuilt the BSA 3 speed in my old Sunbeam,running like a Swiss watch now,thanks again

    • That’s good news, Sean. It was a great design and I used to use one myself, back in the 1960s.

    Thanks for the K type instruction. Took a k type apart this morning and have successfully rebuilt it and it now appears to be working fine. Also got a copy of your Raleigh book, like what I have read so far.

    All the best to you for the new year.


    • Thanks very much for your kind words and all the best for 2014. Glad you found the instructions useful – it’s rewarding to be able to keep these old pieces of kit going 80 or 90 years after they were first used!
