Sturmey Archer 8 speed hub. How it works

bicycles reviews | bicycles videos | bicycles online

1. sooo, as I've understand it, the shifter uses wire to open/close ''teeths'' inside axle. That is what fix some gears and other releases?? What is the closer look inside the axle?
2. 6:46 3 point 2 fuck?
3. How do change the sprocket?
4. Don't grip the axle in the vise without soft jaw inserts!
5. Dan Burkhart, you seem to know an awful lot about Sturmey hubs. I'm a mechanic with some experience and I have an X-RD8 that is acting up. In gears 3 and 5 it feels like something is slipping periodically, perhaps once per revolution of something. If I shift to 7 or 8 something causes the cog to seize up, and I can't pedal. At this point the shifter sticks and won't shift back down below 7. The shifter will un-stick if I touch a few things but I can't see what is un-sticking it. Any thoughts? Thanks in advance.
6. "Fairly simple mechanical device" I wouldn't want to see a complex device! :o
7. i want to put one of these on a drift trike since i don't have many hills around
8. Thx for this! I knew how 3 speed hubs worked, but always wondered how those with more did... this was a great (literal) insight!
9. Where can I get a bike with a Sturmey Archer 8 speed hub?
   What bike manufacturers use this hub in their bikes?
   I never see it in any bikes specs, when I am checking Trek, Cannondale, Specialized, Cube, GT, Jamis, Koga, you name it.
   Why is this?
10. HI .. my curiosity about this system is ... can you shift gears while pedaling ? the reason is i might apply this to an electric moped conversion for more power trough gears :)
11. Informative. Is it committed to the wheel, in that if the wheel needs changing, the hub goes with it too?
12. is this available in the philippines?
13. Bravo. This is awesome.
14. Inner gear teeth seem to be smaller, do they anyway have longer lifespan ten external? What are common problems with with such gears? Does every gear have also ball bearings?
15. well done  very good 
16. Nice video. About torque in internal-gear hubs, please see http://sheldonbrown.com/twist-internal.html.
17. At the rear wheel, where you have the pin and cable entering the speed hub, I don't have it with a little chain going in the hub, but a part I can pull off to get access to the pin and if I look inside the block i've pulled off, I see the cable.  I've put it back on, but can't change gears anymore. I had to take it off to because my chain was too loose and kept derailling. Any video on what's going on in that block and how to pop it back on in the right way? I thought I just had to pop it back on but it isn't that simple apparently. Thy
18. Very good video - thanks for making this. Really well explained.
19. thank you Dan....so nice of you to take the time and lay it out.....
