Hi does anyone ride a Shimano alfine 8 speed IGH in the winter. I have a new one with 650 miles on it and when it is about 20-25f degrees it has trouble shifting and it will skip between gears. Today it was 12f degreese out and it wouldn't shift at all when it warmed up over 20 it would shift sometimes and skip between gears and other times it wouldn't shift at all. Is there any fix for this or is it just not a good hub to ride below 32 degrease. thanks for the help.

I have the Nexus, which is the earlier generation but still an 8 speed. have not had any shifting problems in the winter, though I did have my LBS give it the "oil bath" some months back and so that may help. good luck!

I've put about 250 miles on my Alfine, in temps ranging from -10F to 40F. It doesn't shift as nicely as my old derailleur/friction shifter combo, and it slips from time to time in the 5th gear. The only time I've had trouble with the shifting was after the temp went from to 10F to 40F overnight, after which I had trouble shifting down from 5th and 6th gear, which went away after I lubed the cable housings (generally the first thing I do when I encounter shifting problems).
I've been meaning to give the internals an oil bath, in the hopes that it'll clearing up the skipping in 5th issue and the shocking amount of drag in the hub when the I ride it below 10F, but I haven't found the time to do it (stupid homework :(). I'd start with running lube through your cable housing, to flush out any moisture that might have collected and could be freezing your cable.

By slipping in the 5th gear do you mean it feels like the chain is skipping? Or do you mean it shift up or down?
Because I'm getting the chain feels like it's skipping effect and I thought it was because my chain is getting rusty and worn (or the cable getting worn).
Other than that I had trouble with the cable seizing up, but I could tell it was the cable as I physically couldn't turn the grip shifter past the third gear. Though I think all the WD-40 I sprayed at the cable housing eventually made it inside as I haven't had that problem recently.
Now that the cable is fine the shifting is ok, except for the skipping in the 5th gear.
I have about 400 miles on mine since November. Though I haven't ridden below about 9-10F (-12/-13C).
