Get a rohloff, you'll never want to ride a derailleur geared bike again!!
I find the gear change mushy on Rohloffs and much prefer Alfines in that respect. 14 gears is a nice thing, but I think the Alfine 11 is going to be a better overall buy than the Rohloff. And since I mostly ride fixed, these days, I can't justify the spend on a Rohloff.
If memory serves, my Alfine-11 is costing me around £400, which includes the hub, Rapidfire shifter and various other bits of control gear (cassette joint etc.) - but then I do generally get a good deal from my LBS.
I did consider a Rohloff when I was putting the original spec together towards the middle of last year, but whether it was something to do with the euro exchange rate or whatever, the cheapest disc-compatible SpeedHub I could find was over a grand
It looks like prices have dropped a bit since then but it's still far too expensive for me. However, people I know who have them haven't had anything bad to say about them (other than the price
)
The Alfine-11 is a very nice piece of kit - the shifting is far snappier than my 8-speed, and it's extremely quiet too. Granted, the Alfine doesn't have the range of the Rohloff, and it has three fewer gears, but the gearing on the bike that I test rode felt like it would suit pretty much everything up to and including loaded touring. Once Shimano get the supply side of things sorted out, I reckon they'll shift a lot of them, but I don't think it'll have much effect on the sales of Rohloffs if it has any effect at all.
I did hear whispers that SRAM might be releasing an competitor to the Alfine-11 towards the end of 2011, which could make life interesting indeed but again, I don't think that Rohloff will be losing any sleep over it.
