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.

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 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. Not surprising since the Nuvinci, like most CVT, relys on oilshear for transmitting forces thus allowing slippage and more so with higher loads. Assuming that you are German too you can read his article at: fahrradzukunft.de/17/wirkungsgradmessungen-an-nabenschaltungen-2/ Don't get too excited about the comparison between the Alfine-8 and Alfine-11. For me the 8-speed always feels more efficient than the 11-speed, which may be since I used the 8-Speed with 42/24 primary gearing which is more efficient than the 38/21 I had to use on the 11. Yes those 3 teeth between 21 and 24 make a difference. Efficiency in bicycle chaindrive varies with the size of the sprockets. Below 20t every tooth hurts, above 40t the difference of +/- 4t is almost unmeasurable.

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.

Если голубое находится под нагрузкой и щелкнуть на понижение, то синее провернется по часовой стрелке и собачки войдут в зацепление с драйвером звезды. Далее усилием от педалирования собачку, стопорящую солнечную шестерню, выдерет из зацепления с оной. Гениально, чё. Т.о. если бы эта деталь была сломана, все передачи, зависящие от стопорения солнечных шестерен (2,3,4,6,7,8) просто бы прокручивались педали бы не крутились а при переключении передачи на повышенную - крутились бы назад. Дело было видать в слабоватой пружине сцепления, которую я таки растянул, и в обилии смазки на сцеплении. Нажмите на изображение для увеличения Название: сработал механ
