Hello all,

I am planning to build my ultimate randonneur for the next Prais-Brest-Paris.
I definitely want to go disc, that is why I am chosing a disc frame with 135mm rear spacing.
With this specs, the XT disc hubs combined with Ultegra 6800 STIs and Avid BB7 road brake and shimano rotor would be my ideal choice.

However, I couldn't find anywhere wheter I could fit the Ultegra 11 speed cassette on such a XT disc hub.
I am pretty sure I could fit an Ultegra 6703 3x10 drivetrain, but I haven't found any info on the 11 speed.

Thanks for your help
