they're expensive but worth every penny--rohloff speed hubs. i put one on a surly karate monkey mtb and after having ridden it all over up and down, i would gladly pay twice the amount if that's what they charged. absolutely the best bicycling experience ever. and i have a custom titanium road bike with campy chorus to compare it to. the rohloff is everything they claim for it and more.
i do not work for rohloff.
