Dear All,

The Alfine 11 SG-S700 hub of my commuting bicycle has started to skip when I pedal standing up. Mostly around the middle of the range (5, 6 and 7). I hear a very loud noise and I have to stop pedaling. It does not happen when pedaling seated. When in 6 gear the two small yellow lines are aligned so I guess it is not because of bad adjustment.


I have had this bike for ~5 years but it has only been ridden for ~1000 mi. The oil of the hub has not been changed yet.

Any ideas?


#1 problem is bent/rusted/damaged control cable so check
that first. If the wire is kinked, your initial adjustment
(line up dots) will be off in other gear selections.

If that all looks good and your chain is not obviously
worn/damaged you may have internal wear for which the only
replacement part is complete internal assembly. Quick to
change, not cheap.

If this bike has seen much salt water use, it will look like
this inside:

If on opening there are not obvious rust/crud/broken small
gear bits then, cleaning and oiling makes sense. We grease
ends and bearing assemblies well and fill with 90W gear oil
as we do SA and SRAM gearboxes. The 'permanent' lubrication
so popular now doesn't seem to slow water penetration across
the seals very well. Note King and Parliamentthis is not
recommended by the manufacturer, YMMV.
