Scroll down to the specs, pricing is at the end, with one tab per model. $1500-1900, depending on gearing. I get the sense they'll be customized on order so the price is fluid.

My commuter bike has the Alfine 11sp hub but with belt drive. I don't think I would opt for it with chain drive, since the never-greasy aspect is lost.

Cheers,
