Dear All,

Thank you for your comments and advice. I investigated a little more and I have isolated the skipping to the 8th gear. It only happens after pedaling for a while so it is hard to replicate on a stand. Now, every time it happens, I change the adjustment a little and experiment with the frequency of the skips.

Also, as you suggested, I need to change the oil. The Shimano or Rohloff oils are ridiculously expensive, so I have found this alternative at a reasonable price:

Liqui Moly 1401 GL4 SAE 80 W Transmission Oil

For about $10 per quart it will allow me to rinse the hub more than once and more change the oil. What do you think?

Many thanks again

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?

Thanks in advance

Dimitris

I would think the gear that is skipping is the one you ride in mostly,
right? If it is the case the chain has stretched and the gear teeth has
also stretched, so when it is under heavy load the instead of the chain
sitting in the chain groove it is slipping up and out.Â* causing the hops
or skips. Start saving up your money to replace both the chain and
cassette. You will be able to get many more miles but you will need to
start avoiding the gear that is slipping. Keep the chain clean and lubed
and the cassette clean to get the most out of it. A new or newish chain
may give you better performance but I would not put a new chain on there
until you switch out everything. Get a decent chain and cassette and
definitely don't go with the lightest one around as they will not last
as long. Good luck and safe riding...
