Alfine hub owners
- Thread starter kalex
- Start date
you need to set them up with the 2 yellow markers aligned when you are in a certain gear. There must be plenty of advice on the net of how to set them up. theres 2 sorts of alfine hubs - so find out which model it is first - must be stamped on them somewhere. If you have the shifter the newer model shifter works like other shimano shifters whereas the earlier models work back to front. Onve set up correctly i found that they didn't need adjustment again. try this http://www.elliptigo.com/support-video/ ... hub-on-8c/
Re:
Yes the hubs is set up correctly with the yellow markers and washers.
My problem ( if it is a problem as no experience with these before) is that if I push the bike backwards the crank arms rotate anti clockwise as though it's a fixed set up, should this happen.
I can freewheel and pedal anti clockwise, it's just when I get off the bike and push it backwards that cranks go in reverse.
Also with the chain and gear cable off when then wheel is rotated in a forward movement it's smooth but if I hold the hub cable arm and rotate the wheel anti clockwise is extremely rough through the hub.
Is thus all normal or not.
Keep in mind that I haven't done any service on this but plan to do the oil bath but only if this behaviour is normal

"My problem ( if it is a problem as no experience with these before) is that if I push the bike backwards the crank arms rotate anti clockwise as though it's a fixed set up, should this happen" just checked on mine which is an ebike with alfine . Its done less than 1000km and it does the same.
Re the roughness when rotating backwards whilst holding the gear arm - it obviously thinks you are trying to change gear - its bound to been rough as you are not changing cleanly. If its working ok going forward then i'd stop trying to strip the teeth of the internal gears

Perhaps you need to give the internals an oli bath if you are concerned. Plenty of how to videos on the net. it's supposed to decrease the drag which is a feature of these hubs - hence the backward movement. The hubs in original state are greased lubricated only. the oil dip is to renew the grease but also help with drag.
Re:
When I say hold the cable arm this is only what the actual cable does when fitted ( this was done with both chain and gear cable disconnected), I'm not trying to change gear as I'm not touching the gear levers. I was just trying to find out if it was rough in all the gears or just 1 of them.
All I'm replicating is general usage but on a work stand so I can get my head around things.
If someone came along and said theirs does the same thing ( when pushing the bike backwards etc) I'll be reassured it's working as it should. Then I will take it apart to grease and oil dip it

i think you are over thinking this- you are probably going to die when the unit explodes setting fire to your clothes and you dying in a blazing fireball. remember to get a mate to video it and paste on youtube.If you think it is damaged in some way then take it apart and do the oil dip thing, they are supposed to be pretty tough units. perhaps it just the cup and cones on the axle that need adjusting and re greasing. if it works ok whilst cycling then i think you are looking for problems that don't exist. - how often do you expect to be cycling backwards? Ive already told you mine does the same thing when pushing backwards. not prepared to take the bike apart re the second thing. you dont say whether the unit is new or not. what does the seller say? If you are holding the wheel by the cable arm you are of course putting pressure on the gears. Try holding the gear lever constantly on your car whilst driving for a few thousand miles and get back to me.
Re:
Try reading the very first line in my first post to see if it's new or used.
As for holding it in gear i don't think so as the arm stays fixed when the cable is attached and thats all i was doing.
I'll say it again for you but I've NO experience of these hubs and until it acted like a fixed wheel when I pushed it back in to my garage I thought it was ok. I presumed it would replicate a freewheel cassette.
Thanks for your help though
