Brompton hub gear setup - Sturmey Archer 3 / 6 / 12 speed

Sturmey Archer gears on a Brompton - they work reliably with a minimum of effort

But what if something goes wrong?

This short video explains how to adjust your Brompton hub gears easily for best performance

We also show how the gears are actuated using the lever / cable / gear indicator chain

Just remember - its not some magical dark art, anyone - yes you - can do it!

Brompton should be paying you for explaining how to use their products so well! Thanks, really informative 👍

Your instructional videos are ten times better than Brompton's own videos! Thanks!

I wish my mechanic were so humble, patient and clear

Thank you for this. On Sunday I was riding my Brompton along our local trailway, dropped it into first to tackle a short but vicious slope, got halfway up and the hub gear changed up into third. I just about managed to mash my way up to the top.
Headed home with the hub randomly changing gears. When I got home I noticed that the locknut was halfway down the thread. Had a search and found this video, a really useful and clearly explained guide. Followed the instructions and got it all set up as per your video. Took it out for a test ride yesterday and all is well.

Thanks again for the great service you provide to the Brompton community with these Videos.

This is EXACTLY what I was looking for! Thank you so much for making this video!! Why did no one else make it so simple!?

Really helpful video, straight to the point and detailed enough that I was able to follow the steps. I have just purchased my first Brompton (used) and by the time I got it home I could not change into any of the hub gears. Thought i’d been sold a duff one but your video helped me to identify that the cable anchor had come undone. Now it’s all working fine. Huge thanks. When I need to buy some spares or accessories, I will be coming toBrilliant Bikes!

These films are brillliantly clear and easy to follow. I wish I'd found them sooner.

Can I just say a HUGE thank you for fixing my brand new Brompton (indirectly), saving a lot of time to take it to the shop!!! Love from London 😘

True to your name, this was indeed brilliant and helpful! My local bike shop guys tried to fix my derailleur gear, but I now realize they were messing with the hub gear, which soon became wonky. Now I've got it fixed for real all by myself!

[peterpusey]

Brilliant clear explanation. At the end of a long journey I finally worked out that it wasn’t just that my legs were tired it was that second gear wasn’t engaging. A watch of your video a minor tightening of the cable and second gear was restored. Many thanks.

Really brilliant explanation of how to fix a problem with my Brompton which has dogged me for almost a year! The problem was first caused by my local Brompton 'specialist' who did not reassemble the gear link after a tyre change. Thank you so much!

[ClivesChronicles]

Thank you thank you thank you thank you thank you thank you Thank you thank you thank you thank you thank you thank you!!
Thought I’d broken my 6 speed Brompton as gear 1 wasn’t selecting. Few videos I viewed were useless, then I remembered seeing a video about the hub on your channel. All fixed now! Thank you so much!

I watched this video so long ago when I was first thinking about a Brompton, now I come back because after receiving mine there was a weird noise when I was in the highest gear and pedaling on quiet pavement, even after doing the gear adjustment truth the hole... thank you for taking everything apart and starting from scratch, it was a full two turned loose inside the Hub so there was no way I was going to get it right without disconnecting the chain completely and screwing that rod in. Thank you so much!

[arifini]

Very nice guidelines, you saved my day!! My brompton now is back to normal after following how you adjust and installed it!

[AncientYouth]

really helped me sort out my slipping chain, who'd have thought such a minor adjustment to the gear indicator change would make such a difference

[susiej]

Saved me a trip to the bike shop and I understand how the gears work much better now - thank you!

[Venomator.]

Referred back to this one today as my hub gears stopped working properly on a short ride home! Guess what the problem might have been?
Yarp - the lock nut had worked loose and the adjuster was busy working itself free of the thread! Now sorted, degreased, oiled, wiped off, re-installed and adjusted... ✅ 👏🏻
Thank you much... 👍🏻 💚

[snabelone]

Thanks that helped me understand how it works. The Brompton Manual don't mention the part how to adjust the gear indicator chain at all!
On a 3 or 6 speed gearing, put 2nd gear in and check that 1 mm is showing in the securing wheel nut... Got it!

[thecatsfather]

Thank you for this. Took my two-week old Brompton out this morning and halfway through the trip the hub gear stopped shifting. Checked this video, followed the very clear instructions and it's working again ... well, apart from the missing lock nut which, hopefully, the store still have and wonder where it came from.

Excellent video thank you. Rode by new Brompton last week, got home, chain missing!. Lesson learnt. Ged
