    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 firebird3101@yahoo.co.uk
      If you cannot resolve the problem via Peter, please get back to me.

    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.

    James

    • 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!

    HI my name is giuseppe and i would like to thank you for this very useful resources i have just dissembled and serviced a gh6 dynhub thanks to the info you have provided. :)

    now working well after removing all the rust cleaned and re assemble thank you , now just needs new rim and re spooking but the dynohub as good as the day manufactured.

    just dry battery unit to refurbish and wiring and lights which are in a bad way but not beyond hope , they came off a gents Rudge Whitworth single speed bicycle the frame is in a bad way needs but with a little time and elbow Greece it should look like new when done.

    i was a bike mechanic at watts & Cearns lower brigit in Leeds for some years, and loved the work and some one mentioned about servicing a Sturmey Archer 5 speed well that was my speciality aria as the other guys hated touching them, i still do the odd one now and a gain for people i got my qualification at Raleigh centre Nottingham when the original works was still there, and where i bought my brand new Raleigh Record Sprint the original black and gold one with renolds 501 tubing on completion of my training there as a treat to my self . i still have that same bike in original show room condition

    • Great feedback, Giuseppe – thank you very much. I’m delighted that you found the info useful and that you are keeping these items going. Good stuff!
