i dont know either. i have climbed some steep short grades and never felt any problems with the hub.
i am going to try some climbs with the alfine hub/bike (a commuter bike) that i have near lake tahoe after some configuration. i have a 42/18 setup currently with an ecc. bottom bracket to adjust chain tension. i am thinking a 38 may help but i may have to shorten the chain anyway.

these internal hubs seem like the way to go.

I have yet to see one working so i can only assume how it would work but, how ajustable is the gearing? for instance: I ride in Chch and almost always on the flat,I'd like to put on it either a GT 9er or a jamis dragon 1, i may do a lap on the bays rarely so can i set i up for a bit more speed on the flat?

Is there a local suplier in christchurch?

Are the hubs in the euro style comuter bikes the same thing?

You can only adjust the gearing by changing the gear ratio on your bike. i.e. changing the chainring and rear cog.

Most bike shops should be able to get hold of them. It is a Shimano product.

Some of the euro style commuter bikes will have Alfine hubs.

I'd quite happily ride a belt-drive bike with a geared hub if anyone wants to give me one...

it did for a while - until all the dramas started to add up. Took me a while to work out why he needed to cut a section out of the seat stay, but then I understood that you don't break the "chain"... As if that wasn't enough, the slot out of the chain stay to get accommodate the front ring ruled this out for me...

I see Wiggle have listed the Alfine 11 speed hubs, with zero stock, but stock expected late September.

Adds up to about $800 at current exchange rates... I wonder when/if we will see them in NZ bike shops and what sort of price they will be??

I've been told a tentative date of 6 August, but that was a while ago, so I should find out if that has changed.

Eight hundy would be not so bad.

and that listing says "without fittings". I assume there are some other parts needed to mount the hub on the bike, and you would need to buy cogs etc.

yeh, wheel building + spokes + rim + cables to go on top of that price.

you'd say $1200 all up I reckon. Still half the price of a Rohloff.

half the price for 4/5ths of the overall ratio sounds fair to me too (as long as they handle the mountain biking) :)
