The first thing is to enlarge the space available in the cassete. As i started from a mavic one, i already had half work done. Here is the original:

I also had to touch the hub:

and this is the finished hub:

For the cogs, i did a 25 teeth cog in carbon fiber and I combined it with an old dura-ace 7800 little bit tuned and some old 8sp SRP titanium cogs tuned too.

But the 25 carbon cog broke in a demanding ramp, so now i ride with a 105-dura-ace cassete combination that weights near a ton. The idea is to find some dura-ace 9000 12-25 cassette, disassemble the cogs from the aluminium core and mount they again in my own carbon core, with the appropriate measures. Also, with this idea i´ll be able to mount this 11sp cassete (with 10sp spacing between cogs) in any standart 10 sp hub. Anyway, until i have the money to buy a dura-ace cassette, could pass a long, lonnnng time . Here are the 105 11sp:

Well, and now i have to modify the shifter. First thing is to disassemble it:

Here are some weights:

This is the piece i have to modify:

To do this, first i have to make a tool to hold it:

this is with the piece ready to the new slot:

And here the work is done.

I just have to mount it again, and that´s all. I already rode with it and works fine. My only complain is not to have the new dura-ace cassette to be able to make the lightest 11sp mechanical system "all around the world", but when i have it i´ll post the process here.

First - both in this thread and your other threads you obviously have a wide range of machinery available to you. Do you work at a shop? Is this all at home? How did you get so many useful tools? What do you do for a living?
Second - I like how you decided to further modify your already modified mavic wheels (very impressive) - have you considered getting the new 11-spd compatible hubs and relacing them to your tuned rims, and of course just creating new axles again like you did before?

Is that all you have to add on this amazing piece of art?? Hope that the mods will have some pity with that kind of reaction and keepin you on board...
my deepest respect monchito!
