Don't worry. 7 months of rough rides, and the carbon is still intact on mine.
I would like to say the same about the bearings, but no.
I replaced the CaneCreek bearings with the Neco's, and they fit well too.

@brmeyer135, No no, I didn't try them yet.
Gary from BBInfinite did send them a week or so ago(for free!).

I understand that no seal can stand the bad weather here.
And as normal bearing are rusting, we'll try ceramic ones.
Except a surprise, I won't spend any money for hi grade bearings in the BB and bottom headset anymore.

I installed a Cane Creek 40 headset, as I thought the provided Neco was not good enough.
In the end, it doesn't matter. The bottom bearing is totally rusted after 7 months.
So Neco was probably as good.

From what I remember, the headtube of my 256 looked bare carbon too.
But may be if you scratch a little the surface, you will see some aluminium.

It did put the bearing/cup assembly in the headtube.
And had to press a little, to place the bottom part of the headset.

Sure I'll report any issue.

But after doing it, I'm quite confident to repair any future cracks it they occur.
Cracks is a frequent excuse of the carbon frame haters.
Well... ignoring that carbon snaps all of a sudden instead of bending.

Epoxy and carbon cloth, are finally simple and soft tools compared to what you need to weld aluminium or titanium.
Others on youtube have repaired much more critical parts of their frame.

As you said, I'll probably put a chainstay protector on both sides now.
If you look again at the repair picture there is a serious scratch just on the left side.
I initially though it was a crack after the ride but no.

Andy, I extracted a white sharp debris(not sure what it was), that perforated the frame at the bottom of the hit.

May be the rest of the hit is due to the initial shock.
Or because I didn't see it immediately and finished my bumpy ride.

I will try the DIY option first(because I like to try things, and it is cheaper).
There are plenty of videos explaining how to do it, and it seems definitely doable.
Tomorrow, a package from http://carbonmods.co.uk will arrive home.

And if I mess up things, I'll leave it to a "composite material expert", that will happily do it for... 190€

I did my Wednesday ride, back on a 26" FS (the Rush). What a sad ride it was :-/

After some more research, there is a fair number of single-guy-shops that offer carbon repairs.
And I found shops that sell carbon fiber, resin, etc. in Belgium too.

As CD says, "just" a patch could be enough. As there is no other cracks on the tube except the direct hit.
I'll give this option a try!

I'm afraid I'll have to remove the dust that settled on my old Cannondale Rush, for the Wednesday ride... That will hurt

Arraider, may be you noticed already, but there is a small hole perpendicular to the axle and the nut.
You can put a headless screw there, to stick the nut and avoid loosing it if it gets loose.

Last week, I noticed after a ride my DT Swiss axle was loose. The nut stayed in place because of that screw.
So not only IPlay axle get loose.

brakes from Europe they often come "moto" style

Well... there is only one country in Europe where they drive on the "other side": the UK.
All other countries have the front brake on the left.
