Anyways, i still think that they are light, stiff and beautiful. My complain is that they are no resistant enough. The first problem was with a chainring thread; it dies and i had to made a bigger hole to put a regular chainring bolt. Anyways, not a big deal.
But some months ago, i feel some play in BB. At first i think that the bearings had some kind of movement in the BB, but when i dismounted it i find that was the aluminium axel that had looseness with the carbon rod. It already was a big deal

And here i show the proces i did to repair it:
The first thing I had to do was a tool to remove the left crank nut...

... and a tool to separate the axel from de crank.

Here are some weights:

I thought in lightening the axis, but finally it seems to me a litle bit dangerous.

then I needed a device to glue the rods perfectly aligned.

before glue the cranks I realized that the left crank nut would not tighten against carbon fiber, so I had to fill it with epoxy putty. This particular case is inexcusable and I think it's because of a poor design. The nut should not have been just a embellisher.

and finally i could glue the cranks:

as glue i used a mix of epoxy and these little pieces of carbon fiber

And here the cranks completed.

I hope to use the cranks for a few years more. May be i´m too naïf, but I think a +1000€ cranks should not have given me any problem, at less, not so soon. Anyways, it still seems a happy ending.
