Re: Shimano Alfine 11 - Longer term reliability

OK, thanks JBro I'll let you know how I get on...... Try my 2 years old book... plenty of pictures and (sorry 'bout that...) even more words. I was working on a different problem, but stripping it down to the very bones was just too interesting to not try... THIS is your link to get it. Free to any...

Re: Shimano Alfine 11 - Longer term reliability

quote="zeluzel"] The "second" hub i worked on is now operating for some years i.e. some 8000km and i am basically happy with it. Every once in a while she gets mad at me and slips a pawl. Lets say it does it about once in two weeks . For me sounds absolutely unacceptable, especia...

Re: Shimano Alfine 11 - Longer term reliability

Oops... so i've been too harsh it seems. Yes the premium Inter-8 has roller bearings as same as Alfine, so ETA is similar. But yes, too, the lesser efforts taken on sealing the hub will make it last shorter - or require more maintenance, whatever you prefer. Using twin chainwheels IS an option. I do...

Re: Shimano Alfine 11 - Longer term reliability

Hi, long time no see... Calling just to say: "Second's Out!". My book grew to 52 pages, contains more photographs and - maybe - can start further discussions about the "magic" within pawl engagement profiles... Here is your link for everybody who is curious: https://c.gmx.net/@3...

Re: Shimano Alfine 11 - Longer term reliability

I'll warrant the assist mechanism will be used to some extent on every down change; its duration of activation will be mille seconds because as soon as the pawls are engaged the move will be initiated and the spring will take over thus retracting the assist pawls again. Sorry this is not true. The ...

Re: Shimano Alfine 11 - Longer term reliability

The discussion becomes somewhat theoretical. Reality and expierience are proof enough, i honestly think: i) There ARE hubs out there which have been damaged in a way that excessive forces upon down-shifting degraded their inner circuit. ii) We MAY think that the design should have considered what fo...

Re: Shimano Alfine 11 - Longer term reliability

I was under the impression that the shift assist was an integral part of the design. The selector mechanism on its own is not strong enough in certain circumstances to operate the shifter and will result in it being bent. With the pedals loaded, shifting UP simply wouldn't do, all you get is a loos...

Re: Shimano Alfine 11 - Longer term reliability

Just a short (?) update... i filed 2/3 of the shift assist pawls (forgive me for keeping "my" naming, please...) peaks away, maintaining more or less the previously existing angle, so the outer slope lost material on @3/4 of its length. When retracted, the pawls now appear to face inwards,...

@mjr: that's the thing about cloud services - you never know what they really do... I use firefox 58.0 on XUbuntu currently, that went ok. The german message says it does not like your browser SETTINGS, not the browser itself. GMX is a german provider who really likes to pop-up ads and the like. Per...

Re: Shimano Alfine 11 - Longer term reliability

Thanks, Brucey, for your answer. Very impressive how many details you actually know. I guess it will be a good thing to wait some more discussion and i will finally try and remove most of my faults from the document. Especially regarding the "safe window". I also understand now that findin...

Re: Shimano Alfine 11 - Longer term reliability

Hello to everybody. Please excuse my poor English, i am from Germany. I own two A11 (old version i.e. SG-S700) which are both far from trouble-free. I am not an expert, but i do spend lots of hours on things which don't work as i expect... Thanks to this forum i got ready to strip down the unit(s) a...
