I have Nexus gear box hub and it looks pretty similar to alfine. I have disassembled and assembled it and you have right - it is complicated. But not impossible if you have good video tutorial which show how to put parts together. :)
You all prolly dont give a damn but does any of you know a tool to log back into an instagram account..? I stupidly lost my account password. I would love any tips you can offer me!
@Kristopher Lennon thanks so much for your reply. I found the site thru google and Im waiting for the hacking stuff atm. I see it takes a while so I will reply here later with my results.
Have done about 4000 km on mine so far without drama. Seems to leak a bit of oil maybe but smooth and solid. After watching this video I have new respect for both design and manufacture. Wow.
They dont mention that the Alfine 11 is a pig to stop jumping. Having pushed three more gears into the same size hub tolerances as a result are lower. Trying to adjust it to stop jumping is like attempting to stand a pencil on it's point. Perfect adjustment is NOT where the yellow dot's line up. The best you do is reduce it to a minimum by trial and error which in my A11 is about once in every thirty shifts. I have a Nexus 8 speed that has never jumped.
@@fractalofgod6324 The 8-speed is the better choice in every way. If you want that hub for commuting / touring you gain nothing since the three more gears extend the range on the long end which you will almost never use.
I have used and abused the 7- and 8-gear hubs for decades and love them (except the first Inter-7 which had pathetic efficiency) but sorry Shimano the 11-gear Alfine is anything but "..fine" That hub is CRAP! 1.) The internal gearing is much too long, and it's not allowed to compensate with shorter input gearing than 38/21. So the added range compared with the 8-gear hub is wasted. You just get three additional longer gears you will almost never use instead of gears below 2m which would have been useful on uphills with touring-baggage. 2.) Quality issues! I had serious trouble with the hub skipping/slipping gears and occationally letting the pedal fall through more than a quarter turn which once lead to a painful crash with extensive grazings on my left (from upper arm to wrist and knee to ankle). This skipping is a known problem and regulary discussed in bike-forums, but totally ignored by Shimano. 3.) Quality issue, seconds: My Alfine-11 now busted a bearing in addition the the above problems, which not only made the crank drop completey but also left me with a wobbly rear wheel (a few mm play in the rear axle) barely able to keep control to stop the bike without crashing another time. I'm done whith this heap of junk and going back to 8-speed. And before you ask: YES - that hub has been serviced and adjusted correctly to specifications. This did not keep it from and destroying itself in just over 4.500km I'm thinking of personally slamming that busted Alfine-11 on one of the marketing-reps desk at Paul Lange next time I'm in Stuttgart.
Thank you for your comment. My Alfine-11 is total loss, even I expect, with only view kilometers. Maybe 2-4000. (Bought the bike used) But failed to maintain it properly. Reading, if again investing in Alfine-11 makes sense, or if I should switch to Alfine-8. I think, you helped me. Don't know, if these experiences are only very view from very many sales, or if this Problem is more severe to consider.

@@danielbieling Andreas Oehler did some efiiciency-measurements on the most common hubgears, and comes to the conclusion that the NuVinci is not the best choice strong riders.

Very interesting animation! Funnily enough considering the target consumer is the commuter, the content of this video is waaaaay outside their comfort zone. Who's it for??
It actually has a long service life. And even then, Shimano has to sell them after all. If they make everything from hardened, rigid, high quality steel, it would last forever and you'll never buy another one or service/repair this one... That's just how business works
No, there are steel races inside the aluminum hub shell. All the bearings are exclusively steel-on-steel. I have a 1st generation Nexus 8 on a 13-year old bike I bought with a ton of miles; just took it apart to clean and lube and there's almost no wear to be seen. It's far less susceptible to weather than any derailleur setup, and shifts faster too. For a bike you'd rather ride than fiddle with, the 8-speed is dope; reputedly the 11 is more fragile and finicky.
Shimano's stuff is tough & durable, usually. Is Alfine as durable as Rohloff ? Or reduce the requirements, 2-5000 km distance Alfine can have not any problems to happen? I would like to try a internal hub gears system, but Rohloff is too expensive
Of course it isn't as durable as a Rohloff. But, the Alfina doesn't cost $1500. Although, a Rohloff will last you the rest of your life. Cheaper in the long run.
Even the little lower category Nexus i8 of this masterpiece is working fine and reliable since 15000 km in our all seasons used pedelecs. Many people commenting negative have no clue. Of cause it's not made for competive sports and supposed to serve torque up to 60 Nm but for that it's made for it's just excellent when you regulary doing each 5000 km maintenance by a person who knows what to do.
This is the future of bikes. Add Gate's carbon belt and you have a perfect non-maintenance bike. I can't wait to get rid of the dirty drive set. Hope to enjoy this wonder soon.
A hub needing an oil-change once or twice a year is not what I would call "maintainance-free". And BTW: That belt will get dirty like any old chain from the leakage.
thanks, nice video to help understand the ways these paws, clutch, and planetary gears work! I needed that to service my 6 years old Nexus 8 that is si slipping/ missing lately..
Been commuting on an 11 Alfine Genesis for a few months now and in 1000miles I have had 3 minor mid shifts under light load and barely discernible at all. A bit spongy on set off for about 1/8 of a crank and then feels rock solid. Nice and quiet too.
Ich fahre meine Allfine single Speed 11Gang seit 2013 ca. 86000 km ohne Schwierigkeiten anfangs mit regelmäsiger Wartung jetzt bin ich umgezogen in eine andere Stadt muß ich alles selber machen aber da gibt es nichts zu tun ausser nach gefühl alle paar jahre mal einen Ölwechsel, aber ich denke der ist auch überflüssig. Also Ketten,Ritzel, und Tretkettenblätter tauschen kommt öfter vor. Wer sich einmal in diese Schaltung verliebt hat bleibt bei ihr auch mit Daumenschalthebel.
I just had this idea for greatly simplified internal hub gearing: ...../ >< ......\ You just use a a small diameter geared cone on the chainside (left) that can slide up and down a large geared cone on the drive side (wheel, right) using a friction shifter .. ??? Why isn't this the greatest idea ever? 😊
I want one with a belt drive for ultra low maintenance. Seeing as how I would be limited to only one front gear, what Shimano dropbar shifter should I get for the left hand side? One that has the brake only. I want the di2 for the right.
Tiptronic gear shifting for your bike! Not particularly interested in it myself but I can see why it would be perfect for lots of people. I can just imagine the torrent of outrage if a rumour about UCI testing started. Strokes all 'round for the 'purists'. Joking aside this would be a perfect system on a general use or commuter bike. I wonder how much of a debt this system owes to the Sturmey Archer stuff, which apparently is still being produced, somewhere.
how hard is to make this 130 mm, and add a couple of spacers for wider range of use; than having to hack it ?? the Rohloff is way too expensive to just test for fun
Compared to the old beefy 3 speed Schwinn planetary's that were bullet proof, these look kind of frail .By the looks of many comments below they are frail .

How well does it perform over time?
They leak.
Gear hubs leak by design. To relieve pressure. If they were air tight the case would crack when internal pressure increases from heat.
Why there is no new speedhubs? No direct drive like in Rohloff
