I let the machine shop to cut off 1mm of the Ultegra 11s cassette and now it fits perfectly on 10s freehub.

EDIT: it fits to the Novatec hub, but does not fit to the DA7800 hub. DA has 0,8mm less room.

That's a 28T cassette ?

Do note that it will not work with some wheels once you have a 25T to cog. And it will not work with a most wheels if its a 23T. As the rivet flanges might hit your spokes or your RD might do that on the largest cog too.

Be careful when you attempt to do the same with cassettes smaller than 28T.

It´s 12-25 and does not hit the spokes.

Cool... but best to take off more (at least 1.85mm) and use thin spacers to fine tune.

I'm amazed that no one is doing this commercially... yet. The machine shop can probably crank these out in no time.

So the reality is that without changing the hub, you can take the 1.85mm off the back of the cassette or the hub.

One is a do once job, but may ruin the hub, the other is do each cassette change, but worst is that the cassette gets buggered.

Hmmmmmmm

For me, the dilemma is that with the CM MTB Disc hub I am using (HDWR-3), I can get an SRAM XX1 or Shimano 10sp freehub only, but with the road hubs (non disc), they do the 11sp freehubs .

It's hard to get suitable info to see what the difference between the two is.

Will have to have a closer look at the options.

I thought Ultegra 11 carriers were carbon, that looks like alloy?

Ultegras are aluminum. These cassettes can be had for <$70... no carbon in them.

The first cluster (pair of sprockets) is on a carbon carrier (unless the design has been changed).
The last cluster of 3 (biggest) sprockets is on an aluminium carrier.
