If you got a Specialized Crux 2016 in carbon fibre like me and want a pair of tubular wheels or more for racing. If your dealer can’t get their hands on a pair of Roval CLX40 in time there is a solution by NEXT Cycling.
They are selling a kit with special endcaps and a modified Ultegra cassette to fit on a regular DT 350 hub. Then you will get space between the cassette and derailleur hanger like you don’t have with a regular hub and cassette:
And of course they got wheelsets too, in 30mm or 38mm:

Maybe it will come more solutions in a close future, we are thinking of a few that maybe will be awesome 😀
