We get a (to me) surprising number of emails questioning whether you can use an 11 speed hub with a 10 speed drivetrain. The answer is yes, I've done it every time I've used my road bike for about a year now. Let me illustrate with a picture I stole from the internet:
The keen-eyed observer will note a thin (1.8mm thick, to be exact) spacer ring on the inboard end of this cassette body. If you are using this 11 speed hub with a 10 speed drivetrain, keep that spacer on when you install your cassette. No re-dishing of the wheel is necessary. No adjustment of the rear derailleur beyond what you might expect when going from hub to hub (i.e. may be a click or three on the barrel adjuster) is necessary.
If you are using an 11 speed drivetrain with this hub, simply remove the washer before you install your cassette.
As G-Love said, yeah, it's that easy.

Do you provide the spacer with your 11spd hubs? I will be in that exact situation once you open up the Rail34 orders…
Yup
Hey Dave,You didn't address a critical point—when running Shimano 10 speed cassettes, do you use the 1.8mm spacer in addition to the stock 1mm spacer, or instead of it?
That spacer is part of the cassette. With a Shimano cassette that comes with a spacer you use the spacer, end of story.
